Color display showing max 450 points providing gapless covering up to the full frequency range. But, I am very tired of comments about technology made in china or people who insinuate things are not good because of chinese production. There are many different fields in business. https://tinysa.org/wiki/pmwiki.php?n=Main.MenuTree. IMSAI Guy did an updated video teardown also. The base specifications on this are remarkably close to the NanoVNA which makes me think that theyre roughly the same thing under the hood. Check for non continuity with a ohm meter! !! /tinySA-user-manual-march2021.pdf. A very simple to build, Spectrum Analyzer, Page last updated on The dropped a stand of drill pipe and it hit a crossmember. Philip G7JUR In-case you missed Kurt's excellent Hamcom article at . Sadly, try as I might I was unable to get TinySASaver running on my Ubuntu machine. First Impressions A caveat: I'm by no means an expert on spectrum analyzers. Prefer to Read a document instead of original NANO board tinysa spectrum analyzer manual pdf is & ;. A built-in calibration signal generator that is used for automatic self test and (low) input calibration. . More info on this build is shown below and will be updated when required: Please note that this is not a project for inexperienced builders, there is no kit nor part by part assembly instructions. I have noticed a couple of other annoying issues. Now I wish I had waited battery + display! ie Control PCB, std SA RF board, then optional TG pcb. However I am not seeing a sweep output ramp and/or a trigger out that would be nice to sync the tracking generator. A second RF board can be stacked on top of the normal RF board and with some slight changes to the control board to enable two additional Chip Select lines to be added to control the Si4432 modules, and of course suitable software to do it, we have a SA with tracking generator. 2023 To get the best measurement performance, it is important to pre-scale the input signal to the level where the detector has its best trade-off of linearity and sensitivity. This happened to me the other day, and like many of you it was one of those times when I puzzled to myself: I wonder what I bought this time?. Hi, is there a similar device, but with a proper BAS output ? Posts from new users require approval from the moderators. This includes: harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing. They are in the top centre of the picture, in case you haven't spotted them. MicroSD card slot for storing measurements, settings and screen captures. There is even a branch that is open source (last I knew) now called the simpleSA that is based off the original tinySA design. Is it asking too much to bump the screen size to 7? . The V1 PCB is the only PCB that has been released and built by several builders so far. Use leaded 1/8W preferably components, as they are smaller and fit nicer. As the sweep width is widened, the sweep speed will slow. 100 MHz vs. 100 kHz is an important difference in capability, while casing is not that dramatic. I took som examples: Xiomi phones, ZTE phones, branded chargers, Radio products like Baofeng, and the list continues. As far as combining the two softwares, the short answer is no, as there is currently no hardware that could provide both the spectrum analyzer and VNA functions. Companies making transformers are close to companies making copper wires Last updated on . It looks awesome for the price, but, the main thing I want an SA for is to look at sources that are emitting noise, and ambient noise. 24th Aug 2020: The V2.0 PCB panels have arrived and I have quickly assembled them and tested OK. Groups.io, tinysa@groups.io Notification . Some modules on eBay will not cover that range, so ensure you buy the 240 - 960MHz modules. When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 0.1MHZ-350MHz, UHF square wave output between 240MHz-960MHz. Some with real branding, some with counterfeit branding, and some they dont even put a brand on because it would cost too much in ink! https://www.arduino.cc/en/main/OldSoftwareReleases You will need to add the ESP32 capability to the IDE. (11th & 24th Aug, see above information) As for the needed software, that's beyond my capabilities. The first thing I noticed was that the fundamenal was off a bit from the where it should be. Thank you -- 73, Bernie, VE3FWF (most typos in this message were generated by highly sophisticated auto-correction software) This is well known. The top has a power switch and a jog control. That cuts way into the usable dynamic range. I bought (something like?) (Comment Policy). As for me, since everything is MADE IN CHINA why should I buy it in the US unless it isnt available from CN or I need it tomorrow? NOTE: this allows the logic levels into the PE4302 to be approx. I "might" alter the PCB at some time to V2.1 to correct that, but right now it's not on my to do list. Underneath lay the expected RF wizardry, including the expected Silicon Labs chips. Note the provision for extensive shielding. The tinySA FW is based on the NanoVNA FW created by edy555. Color display showing 290 scan points covering up to the full low or high-frequency range. A built-in calibration signal generator that is used for automatic self-test and low input calibration. The main issue is quality control, there are many US companies that manufacture things in China and the only way to insure you are getting what you specified is to have your own QA/QC people on site. Best way is with two soldering irons, simply heat both ends of each resistor at same time and the part will come off easily. The parts removed are small, 0402 sized, so keep this in mind if you decide to do this modification. V2.0 PCB mods to use the tracking generator (TG) function. By: Eduardo Alonso <ea3ghs@.>. There are several numbers of great companion PC tools from third-party. Pretty good though. Download the software to put the firmware on the tinySA from here. The more space available could be turned into circuitry to obtain more functionalities (SDR, SA, function generator, multimeter, etc), not to mention bigger longer lasting batteries etc. Of course it depends on the use. 2021.3.15 2021.3.15 SDR . R29, R30 & C9 need to be fitted if the CAL output is required. Then a wave using cable converters for the front end. A spectrum analyzer combined with a tracking generator, makes a very useful instrument to also allow sweeping of filters and such things. The tell-tale indications for internally generated spurs is that they move faster or slower than the expected rates for harmonics, or even moving in the opposite direction, or moving at the wrong rate as the center frequency is changed, i.e., if you change the CF by 1 MHz, any signal that does not move 1 MHz is a spur. So theres probably plenty of room for operator error and misconceptions about what a spectrum analyzer can do in the tests that I ran, but I still think this is valuable as an example of what a tool like this can do in the hands of an enthusiastic newbie. (it's for DRAFT V2 PCB, NOT the v2 in Sch's above, so some parts are not required for the V1 PCB, refer to the Sch..). 2. Page created by vk3pe (see QRZ.COM for contact details) April 2020. Im facing the same problem. The firmware has features that require spending big bucks to add to my expensive spectrum analyzer. NOTE:- To use the V2.0 boards in a tracking generator setup, a second "RF" board is needed from a second panel. You get spurs with input above -30dbm. Too bad the tinySAs frequency range stops at 960MHz, thats right around where the output of a consumer satellite low-noise block downconverter (LNB) output starts. (Software is not released at this time) You can see the results of the test below when compared to my Rigole SA-TG which obviously costs a lot more than the "simpleSA". That 28.8 MHz means theres plenty of aliasing for low band stuff, and the 8 bits limits the dynamic range. The attenuator helps. He says that the fact that the signals other than the main one moving faster than the main one indicates these being mixer artifacts. You can always use the help command to get a list . There are also other Spectrum Analyzer factors such as resolution bandwidth, IF bandwidth and type of detector (peak/average/log/minimum) that are not as important considerations to a vector network analyzer that is generating its own controlled stimulus signal. Much thanks in advance! R23, 24, 11, 18, 19 & 20 need to be fitted as either smd or axial parts. hell i could never afford an hp or other lab quality spectrum analyzers, but i can surely afford a tinysa! I think only the 240 - 960MHz version is suitable. i suspect in the next 10 years there will be more coming from china that will change a lot of minds, even those that are reticent of change will have to admit they have passed us up that is unless we take the challenge seriously now! I suspect many buyers just want a visual presentation of the spectrum. The result is that you end up being waaay out of spec again but at the Low power setting. Erik is pretty clear that the code is still rough, and Im far from a Python guru so I might be having library problems that would be easy to fix for someone with more experience. NOTE: It's not a full blown SA but very useful nonetheless. On the other hand, the RTL-SDR gives you real time I and Q samples at 2 megasample/sec or more over USB, making it a very flexible receiver when used with a computer. PE4302 attenuator module (eBay) ( ?? ) Be patient, it is possible to fit parts like this. The industrial field is not the same as consumer I think this message isn't appropriate for our group. The new topic will begin with this message. 2 A peek inside of the TinySA, Spectrum Analyzer Fig. aaaaaa wrote a comment on CH552 USB Knob. Overall, for $50, its a pretty handy device. After connecting the tinySA to a PC using the a USB cable a serial interface will become available on the PC. This is a spectrum analyzer capable of operating between 0.1 - 800 MHz, or 0.1 MHz - 6 GHz with the 'Ultra' mode enabled. The instructions, however, appear to be written for use with a NanoVNA, not a spectrum analyzer and unfortunately most of the tinySA settings are not available in tinySA-Saver, at least that I could see in the version tested in early January. Cannot retrieve contributors at this time. You signed in with another tab or window. Manual (0.2, 1, 3, 10, 30, 100, 300, 600 and 850 kHz), or automatic: Signal generator: . I grabbed my Baofeng UV-5RA, a homebrew 40 dB attenuator I built a while back, and an unwieldy collection of adapters to connect everything together. I also noticed a small forest of spurs starting at 500 MHz and extending all the way up past 800 MHz. For 50 bucks, this thing is sweet! Dave, M0WID has also done much work on the software, using the ESP32. These reviews mainly deal with classical sine wave performance, with modulations such as AM, Really neat what could be done with the cheap SI4432 modules, the variety of cheap MCUs and now to see a marketed product I even own. Donations can be done via credit card or PayPal. At fifty bucks it is hard to say, no. If anything, it would be nice to have a, disposable, piece of test gear for situations where a lab grade instrument with NIST traceable calibration is not required. Below: The "RF module". Episode 1325aI try the ultra mode to allow frequencies up to 6GHz. and took us a long time to catch up again. Gerber's will be available soon. Caution, not all Si4432 modules maybe the same layout as this ! I have 3 tinySAs, and might get another to keep in the car. Ill update as soon as I get a chance! A higher performance SDR such as the ones made by Airspy and SDRPlay are even better for that but are more costly. Otherwise, using the built-in sweep trigger and span width adjust might suffice as a messy work-around. Using a PC is not mandatory, "simpleSA" can be used on it's own, using for example, a Li-Po battery bank as power source. Its a $60 piece of equipment. The 'simpleSA' PCB by vk3pe, shown on this page. This drawing gives an idea how the "simpleSA" is built. Unfortunately, the tinySA PC software only runs on Windows, which I do not use. This low input impedance may load down (and possibly damage) the circuit you are trying to measure. China sells cheaper products. The TG board is mounted on top of it. Since the attenuator module comes with two of these which must be removed,you can re-use one of them for the RF input. But if you want to do EMC pre-compliance probing and stuff like that, Id take the tinySA over nanoVNA for that job. ), On the SA RF board (the one behind the control bd.) Be careful as there are signal output on the TinySA input port.Be a Patron: https://www.pa. This repository contains source of tinySA firmware. Gregor said: Is there a chance this could be used as a oscilloscope (with modified SW)?. The latest firmware has added optimizations for these signals, The latest firmware adds an optimization for observing AM modulated signals. One reason for this is their superior quality compared to western products, and this for only a fraction of the price. Commercial ones are available and range from high end instruments either new or second hand, to relatively low cost units like the Rigole and Siglent instruments. The tinySA are a small spectrum analyzers and signal generators with some nice capabilities: A short 7 minute video introducing the main features of the tinySA can be found here.A short introduction video to the tinySA Ultra can be found here.Many more videos in my YouTube channel. Here's how I fitted them, using smd parts. These pictures of the V1.0 PCB give an idea of how the "simpleSA" is built. BUT it is all MADE IN CHINA. (V2.0 is almost identical, the parts that need to be added on V1 are present on V2.0) I will add this specific info soon for V2.0 As of 24th Aug though, nobody but myself has V2.0 panels. Is it possible to combine the two softwares into one on a single device? (I do need to wear my glasses to use it, but thats true of the NanoVNA, too. Of course it was only then that I looked in the box and noticed the wrist strap with the attached guitar pick-like stylus a thoughtful accessory indeed. . This means that a signal on the exact same frequency that the SA is currently at, is generated and displayed, forming a plot of the response. Along with the tinySA, which is about the size of a deck of playing cards, the box contains a pair of SMA jumper cables, a small telescoping whip antenna, a female-to-female SMA adapter, a wrist strap, and a USB-C cable. I tried playing with the modulation function, and it worked pretty much as I expected. Really you need an LNA. However, I would happily pay 20-30 more bucks just to have a 7 screen. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are . Signal Generator with two output, sine wave output for 0.1MHz - 350MHz and square wave output for 240MHz-960MHz when not used as Spectrum Analyzer. The tinySA is a mini portable spectrum analyzer, for the MF/HF/VHF bands from 100 KHz to 350 MHz and the UHF band from 240 MHz to 960 MHz in degraded mode. this earlier this year, https://www.banggood.com/Geekcreit-Spectrum-Analyzer-USB-LTDZ-35-4400M-Signal-Source-with-Tracking-Source-Module-RF-Frequency-Domain-Analysis-Tool-With-Aluminum-Shell-p-1494125.html?rmmds=search&cur_warehouse=CN. I will probably buy a TinySA. The minimum level is ~0.7 * 3v3 = 2.31v so there is a margin but not a lot. I talked about this a bit in one of my $50 Ham articles, and weve seen comprehensive analyses of spurious emissions from these radios that are far more in-depth than anything I could come up with using the tinySA. The strongest spur was about 43 dBm down from the fundamental. project aim to provide an useful instrument for the RF Im not entirely sure what I paid for the tinySA like I said, I tend to order these things and then just forget about them. If tinySA covered 950 MHz through 1525 MHz, anyone on Earth wanting to point a free-to-air (FTA) satellite TV dish would seriously be thinking about buying a tinySA. Id like to hear what others have to say in regards to this assertion, or why I might be incorrect. The Group moderators are responsible for maintaining their community and can address these issues. A small problem was found though, 2 track cuts have to be made on one PCB. I recommend doing this. A suitable IF tap buffer and some amplification will be required before feeding into the simpleSA in this mode. I noticed that the firmware on your unit is pretty old. (50 x 100mm and approx. (Comment Policy). Maybe you have not noticed, but there isnt much made in CN. Thank you for the link. I do also carry a NanoVNA because of its LCR metering and time domain reflectometry for cable faults, but I might give this one a pass since Im not a serious RF expert. I found two Si4432 ISM transceiver chips, presumably one each for the high and low range of the tinySA. I figured Id have to bust out the Hakko to take the tins off, but luckily theyre all spring-clipped to the ground plane, so removing them just took a small screwdriver. About. You can put a spectrum analyzer into zero span mode with the power detector in linear mode (not logarithmic mode) and then adjust the trigger, sweep time, vertical position, and video bandwidth until you get a stable and meaningful time domain display. Heres the teardown video link: Ultra mode is disabled by default but can be enabled using the command CONFIG/MORE/ENABLE ULTRA using 4321 as the unlock code. A spectrum analyzer is a tool that allows users to visualize signals on the radio spectrum. local time. . Now you are using a spectrum analyzer as a kind of time domain oscilloscope. Ive got a bunch of li-ion cells in view of me right now labelled things like 5200mAh 9900mAh etc. DISPLAY controls various aspects of how the signals are being displayed. Watch [IMSAI Guy]s video after the break for his opinion. This resolution filter is swept across the desired frequency range. The Group moderators are responsible for maintaining their community and can address these issues. It *injects* its own signals as part of the measurement process. standalone with lcd display, portable device with battery. The original tinySA uses several eBay modules which can be just connected up with co-ax cables and wires and connected to the PC. On the V1.0 PCB, to use the "reference output" (~-30dBm), the components shown in the Schematic for GPIO2 output, need to be mounted on the rear of the RF PCB and a thin cox cable (eg RG174) bought out to the housing chosen for the project. Those products are cheap and also crappier than more expensive products. You can even build your own, although a fairly complex project, if you look on the web for Scotty's web pages. Last year, there were 25 million more companies in China than there were in the US. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. . The tinySA is a handheld 0.1 - 960 MHz spectrum analyser that is designed, developed and now sold from Eindhoven, The Netherlands. For more information consider joining the HBTE Group as per link above. There is a picture just below here though show how this can be done. Presented here is a minimal cost, "tinySA(tm)", an instrument which can be home built quickly and easily, from low cost modules available on eBay for example. This cannot be undone. It can be varied to a number of different frequencies. Am I missing something? At about 8 inches, or roughly the size of a paperback novel, it was much easier to read than the screens on these little things. . Is there a printable manual, like in a PDF. aaaaaa wrote a comment on CH32V003 Mini Game Console. Try these sites: Theres a wiki here: https://www.tinysa.org/wiki/, And the groups.io group here: https://groups.io/g/tinysa/topics. The conclusion that IMSA Guy reaches about the spurious indications was incorrect. The latest firmware is 1.1-24 and is located here: http://athome.kaashoek.com/tinySA/DFU/ there are a lot of new features regarding am demodulation and other things. Baofeng and get $100. A second option is a PDF version of the wiki, which allows for easier reading for some people, . Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. ie for the 4 inductors, fit a 0 ohm resistor (in place of L8, 9, 10, 11) and fit a link across the SAW filters. To AVOID SHORTS TO THE GROUND AREA , place a small piece of insulating tape under the parts. Regards. I have incorporated the required changes in a V2.0 version of the "simpleSA" boards in future. (Pictures may not show the mods detailed above). The names tinySA and tinySA Ultra along with the tinySA logo are registered trademarks owned by us. The . The Ultra version brings enhancements to the frequency range, signal . Nobody else is allowed to use the name tinySA It may not be the latest version there. Load both RF boards with all components, except for the variations below (R35/R36). Using this docker image and without installing arm toolchain, you can build the firmware. 10th August 2020: I have now ordered a small batch of the V2 panels for testing the Tracking Generator concept being worked on by Dave's software. A few weeks ago the tinySA Ultra was released. From the tinySA.org website: A lot of cheap scopes and PC-based scopes can do spectrum analysis, too, of course, so this isnt as exotic as a VNA. Nobody is taking you wrong, youre taking honest words from people with free speech as if they are some sort of political statement that were crafted based on who is being talked about. This hardly makes a fully usable and portable instrument so I decided to make a PCB for the "simpleSA" project and it is shown below. Id like to have a very basic spectrum analyer, but with a real screen. Significantly better bandwidth and a lower noise floor ~100dB for the frequency range spec. What does a Spectrum Analyzer do? I suppose most of us have had the experience of going to the mailbox and seeing that telltale package in the white plastic bag, the sign that something has just arrived from China. The schematic is in two parts, Oct 12th 2020 NEW Schematics (errors etc corrected.) Wide tuning range, but varying circuitry afterwards. FREQ sets everything related to the frequency range to scan. The signal was much cleaner here, with only a few spurs, the big one being at around 270 MHz. Twice as fast for the 2nd harmonic, three times as fast for the third, and so on. It's easier to fit if the 'thin' side of the bead is uppermost. The other signals shown with Markers "2" & "3" are harmonics of the Cal signal. If new to smd work, some patience may also be required ! The ESP32 by the way, can be programmed using the Arduino IDE environment. For those of us who prefer a real manual, Kurt Poulsen, a ham from Denmark, has written up a comprehensive how-to document that might be of help. With all the pleasantries dispensed, I turned to the one task pretty much every ham will want to turn a spectrum analyzer on: finding out just how bad the signal from a cheap handy talkie is. Beyond any doubt in my mind, you are radiating (and possibly reflecting) significant energy with that pictured attenuator which could affect measurements in a myriad of ways. I never noticed him talking about Chinese product quality. Other than the occasional misinformation, its overall a pretty decent set of videos.
