Previously the standard tinySA was released back in 2020. The following files have been uploaded to the Files area of the tinysa@groups.io group. . I tried playing with the modulation function, and it worked pretty much as I expected. Try these sites: Theres a wiki here: https://www.tinysa.org/wiki/, And the groups.io group here: https://groups.io/g/tinysa/topics. If new to smd work, some patience may also be required ! Due to the low cost and very small form factor there are certain relevant, See left navigation bar for more subjects. SEE BELOW: Building V1 and V2.0 PCB's. Pretty good though. (On the V2.0 PCB, these parts will be part of the PCB.) A built-in calibration signal generator that is used for automatic self-test and low input calibration. 1.3 MB.
The TinySA doesnt have a front end tracking filter, so strong out of band signals can cause problems. Prefer to Read a document instead of original NANO board tinysa spectrum analyzer manual pdf is & ;. A spectrum analyzer combined with a tracking generator, makes a very useful . Is it worth it? . Find the code here: I stand corrected. local time.
*Reference ONLY the draft copy of the Bill of Material (BOM), an Excel file. 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.
A spectrum analyzer is a tool that allows users to visualize signals on the radio spectrum. Hi all. For 50 bucks, this thing is sweet! I have 3 tinySAs, and might get another to keep in the car. Don't apply too much heat to these pads ! It's a good idea to have this. 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! AN-62 TinySA.doc (12/8/2021, kh6htv) p. 2 of 9 Fig. NOTE: I think only the 240 - 960MHz version is suitable. If a signal has harmonics, they WILL move faster than the fundamental. The PE4302 module has 12k pull-downs on my module. Of course it depends on the use. The results were not pretty. With the basics out of the way, I took a look at the tinySAs built-in signal generator. This is NOT to say that these are the only, nor even the best deals on small scopes, I just went to where I knew I could find some. Go to file. In fairness, I would think that you should add the followup link. You could probably modify the firmware to get some functionality, but I would guess the frontend would not be sensitive enough to be useful. Really isnt the same as the NanoVNA design at all. $7.50, 2 x Si4432 "RF" module (eBay) (2 for $5.00). 2023
Tracking Generator? The Ultra version brings enhancements to the frequency range, signal . If not shure about quality dont buy but stop why do people always want Ferrari performance from a Volkswagon beetle? Spectrum Analyzer with two inputs, high-quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz. The latest firmware has added optimizations for these signals, The latest firmware adds an optimization for observing AM modulated signals. You signed in with another tab or window. The input/output specification of the tinySA is split over the 4 modes Low input mode spec: Input frequency range from 100kHz to 350MHz (with some limitations down to 10kHz) Input impedance 50 ohm when input attenuation set to 10dB or more. Mine isnt that bad, but the NanoVNA to me without magnifying glasses is next to unreadable, and this one wouldnt change much, although Ill probably order one anyway just to support the project. The V2.0 PCB panel has arrived (Aug 19th, 2020). A Spectrum Analyzer (SA) is a handy piece of gear to have in the Amateur Radio shack. The tinySA is a spectrum analyzer. Nobody else is allowed to use the name tinySA To AVOID SHORTS TO THE GROUND AREA , place a small piece of insulating tape under the parts. 2.5v. His videos focus a lot on observing AM modulated signals. Made in CN. There is even a branch that is open source (last I knew) now called the simpleSA that is based off the original tinySA design. There is an awful lot of good companies in China. aaaaaa wrote a comment on CH32V003 Mini Game Console. The menus/UI are remarkably close to the NanoVNA as well which makes me think that theres a lot of shared code under the hood. 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. Otherwise, using the built-in sweep trigger and span width adjust might suffice as a messy work-around. I do have a Nano VNA, the model with a few improvements over the original bare circuit board. The dropped a stand of drill pipe and it hit a crossmember. I have a nanoVNA and a large desktop spectrum analyzer. When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between .1MHZ-350MHz, UHF square wave output between 240MHz-960MHz. A few weeks ago the tinySA Ultra was released. Add option use or not string lib for fatFS, tinySA3 touch repaired and HAM_BANDS added, env: replace git submodule url as http to prevent failure to fetch wi, Multi band level triggering when not in ALTERN mode, Restore trace table, display center and band freq display, Reduce differences and remove unneeded parts, Repaired USB cfg and help commands: added, Allow more better define waterfall_palette size and use, Select menu Config->DFU (needs recent firmware). Unfortunately, the tinySA PC software only runs on Windows, which I do not use. @Dan Maloney: If your Baofeng was barely in-spec with at the 2nd order product, you are very likely to be waaay out of spec at the 3rd order frequency. Spectrum analyzer let you look at a signal and figure out its frequency components. 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. On Wed, Sep 30, 2020 at 10:46 PM, Philip wrote: Are you sure you wish to delete this message from the message archives of tinysa@groups.io? The following files have been uploaded to Introduction: The emergence of a number of Vector Network Analyzer with the name NanoVNA has led to Hugen, who is responsible for the production and delivery of NanoVNA-H and NanoVNA-H4 as well as NanoVNA-V2_2 where the latter is with either SMA or N connectors, together with Erik Kaashoek has developed a Spectrum Analyzer, named . The other end of the resistor wires go though JP5 and connect to the Attenuator module on the other side. A standard USB cable is plugged into the ESP32 for programming. Im facing the same problem.
Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. [IMSAI Guy] shows a few oddities that he didnt like, but overall, it seemed like a good value. Description of TinySA a real Spectrum Analyzer for little money. One end soldered to the connector pins, the other end linked across the 3v3 supply rail. TinySA is a Spectrum Analyzer Measures the magnitude of an input signal versus frequency Good for analyzing component signals in a spectrum Measuring harmonics and 3 order modulation products Evaluating transmitter purity Spectrum Analyzer Uses Measure Harmonics Evaluate Mixers Measure Spectral Purity of Transmitter FCC Part 97 For those that prefer to read a document instead of browsing a wiki, there are two options. There is an update to the review by IMSA Guy that explains that the tests he performed were overloading the mixer front end. transportation costs. Episode 1325New $120 spectrum analyzer 4" screen100kHz to 800MHz frequency range and up to 6GHz in ULTRA mode200Hz min. I'm unsure if Dave keeps this upto date though. Spectrum Analyzer Features. IMSAI Guy did an updated video teardown also. 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. Please, dont buy from CHINA, you may get an allergy.
The PCBs can be very poor quality, lacking impedance control and proper shielding of RF sections. Youre just triggered and making false accusations. June 29th, 2020: It has been reported that some Si4342 modules have low output in the "Tx" or local oscillator position even for the 150MHz input range due to the on board filters they use.. (The LO runs on the high side of the 434MHz IF, so the LO needs to sweep from ~434 to 584MHz.)
The TinySA also has a more open design (the RTL-SDR is mostly implemented in a proprietary chip from Realtek) and has various useful SA features (attenuators, etc.). A flux pen can be handy also. aaaaaa wrote a comment on CH552 USB Knob. It's easier to fit if the 'thin' side of the bead is uppermost. LO and mixer to downconvert the selected frequency range to a low IF at 870kHz. *For reference only, these are the old draft Schematics. as this relates to the tinysa? For only about an additional $10 US, you get a stand-alone instrument with the TinySA. This low input impedance may load down (and possibly damage) the circuit you are trying to measure. While there are similarities, the tinySA is NOT NanoVNA hardware.

Im curious then, would I be better off with this or with a nano VNA as a first purchase? NOTE: this allows the logic levels into the PE4302 to be approx. About. That cuts way into the usable dynamic range. I did have bad experiences with some companies in China. When the tinySA ultra is not used as a spectrum analyser, it can be also used as a signal generator to output sine or square waves. The TG board is mounted on top of it. All you need for smd parts is a soldering iron with about a 0.5 to 1mm tip, tweezers,a magnifying lamp or similar and solder wick to remove excess solder. A tag already exists with the provided branch name. https://github.com/erik_kaashoek/tinySA Possibly invalid now, see tinySA.org. This project aim to provide an useful instrument for the RF enthusiast. Itll never substitute for a larger, full-featured instrument, but if your only need for a spectrum analyzer is to design the occasional filter or check signal quality, the tinySA is a pretty good deal.
A, [see also links below for later versions]. I do not own a TinySA so I can not say if it has the modes necessary to allow it to be used as a zero span time domain analyzer. There are two pads on the PCB for the "FREQ OUT" and labeled on the PCB rear. This includes: harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing. Luckily, I was able to scrounge up a decrepit Windows laptop and get a compiled version of another program running, so I didnt have to resort to cell phone pictures for my screenshots. eBay prices shown in US$), ESP32 WROVER version (eBay) [NOTE: PCB shows V1.7, 1.8 OK also.] Donations can be done via credit card or PayPal. The picture above shows the output from the "simpleSA"'s internal Cal output signal. Sadly, try as I might I was unable to get TinySASaver running on my Ubuntu machine. 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. 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. (the upper frequency limit AND Si4342 module issues. Switchable resolution bandpass filters from 200Hz to 850kHz.
With Spektrum or GRC, from what Ive done, you can get a slow sweep so to have a wider bandwidth at the cost of sampling rate with the RTL-SDRs. When you were measuring the Baofeng spurs did you have the transmit power in High or Low power mode? The Python program, TinySASaver, is geared mostly toward saving scans from the tinySA, but also provides additional capability, like doing frequency sweeps in segments and exporting data for further analysis. You can build almost arbitrarily complex virtual receivers the GNU Radio software and an RTL-SDR. Googling "TinySA", you will find a lot of reviews of it's performance by hams. This is a great time saver as your most common setup will be available whenever you cycle the power. I searched here: https://tinysa.org/wiki/pmwiki.php?n=Main.MenuTree. The FCC rules on spurious emissions dont seem to cover this band, but they do say that between 30 and 225 MHz, spurs need to be at least 40 dBm below the fundamental. No warranty is given or implied that others may get the same results or that all parts may still be available. Documents for V2.0 are in preparation. It is always best to talk to other people who have purchased the product for their reviews. Probably something like the Siglent SVA1015X or Rigol RSA3015N would be a better choice if you need both a VNA and spectrum analyzer, although the price point is a lot higher. 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?. A caveat: Im by no means an expert on spectrum analyzers. Their picture can be seen much better from the shelve in the shack.
The tinySA was developed in conjunction with Erik Kaashoek a respected member of the electronics community and an outstanding . If not comfortable with this, use leaded 1/8W preferably components. One reason for this is their superior quality compared to western products, and this for only a fraction of the price. Instead of fitting these two beads on the PCB, one is fitted across pads from FB6 and FB7 as you can just see in the picture. But there are two big differences: 1. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. I recommend doing this. The code is already available on github. For more information consider joining the HBTE Group as per link above. Again, this was only a rough test, with a test setup leaving much to be desired. 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. Updated for Software V2.9, 12th July Will need to be updated as other features have been added by Dave, M0WID. does the tinysa have the ability to compete with a 10k dollar (or more) spectrum analyzer? Note the provision for extensive shielding. On the other hand, there is a reason an Anritsu Site Master costs thousands of Dollars.
This cannot be undone. I bought (something like?) Note just how small and self-contained the "simpleSA" actually is ! If you are aware of the tinySAs limitations (which Erik has kindly posted on the wiki), it works surprisingly well. This is just a taste of the "simpleSA" build. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. As mentioned above, the signal generator is used for calibration, but its a pretty capable tool all on its own. Main Menu. As for materials, Chinese steel DOES NOT have effective quality controls. Best way is with two soldering irons, simply heat both ends of each resistor at same time and the part will come off easily. Chinese disregard of IP laws and their blatant lowest cost production standards cause poor quality copies that tarnish these brands and I urge everyone to make sure you only buy the genuine articles, both to be sure you get what you pay for, but also to support the original designers of the real products. . You can see the Menu structure below. Manual. Industries that need specific alloys often get a bait-and-switch when they buy Chinese steel. I have extensive experience with China, both as a project manager on petrochemical projects and equipment supply. Those 3 displays are ridiculously limited wrt resolution and hard to read for us poor old greybeards. Dave, M0WID has also done much work on the software, using the ESP32.
Also, there are PC-based USB scopes. I used some wire wrap wire to do it, it's easier and neater. Here is the current copy of the V2.0 Schematic. TinySA can also be used as a signal generator so with two tinySAs you can make a tracking generator. Thats not necessarily a good thing, but I like surprises as much as the next person, so I was happy to learn that I was now the owner of a tinySA spectrum analyzer. The calibration then proceeds automatically. The left side has two SMA jacks, labeled HIGH and LOW. Thats not the case. You can view the tinySA output on your PC if you use tinySA-saver, which is hacked from NanoVNA-saver, and display the results as big as you can afford a monitor. The V1 PCB is the only PCB that has been released and built by several builders so far. Using this docker image and without installing arm toolchain, you can build the firmware. The newer FW also solves the crash you have seen. china can deliver a product for any market, you want cheap? If you have a modern scope it may already do this function, or you might be able to do a software solution. This Very tiny cool little product fell into my lap right when I needed a way to find the frequency for a pair of radios I was working on. enthusiast. NOTE:- To use the V2.0 boards in a tracking generator setup, a second "RF" board is needed from a second panel. Learn how your comment data is processed. Kurt Poulsen. Badly. The tinySA is a small spectrum analyzer, primarily intended for 0.1MHz to 350MHz input but it has some nice other capabilities: Note I may not always refer . Its a whole lot better than the RTL-SDR for lower frequencies The RTL-SDL (with the front end bypass for low frequencies) has a fixed internal sample rate 28.8 MSPS at 8 bits/sample, then decimated to a lower rate (1-2 MSPS) for the host. Still, as I mentioned, their quality is higher and higher. The conclusion that IMSA Guy reaches about the spurious indications was incorrect.

Major components used:- (Approx. Be careful as there are signal output on the TinySA input port.Be a Patron: https://www.pa. The built in signal generator function is handy, too, and the output level is high enough that you can use it as the LO for common double balanced mixers. Other than the occasional misinformation, its overall a pretty decent set of videos. This is well known. I say this because Ive made similar looking devices. This resolution filter is swept across the desired frequency range. Install the programming software, STM32 Cube Programmer. Learn how your comment data is processed. Details are in the Groups.io HBTE group, search for post #846. oh yes they can deliver with the best. tinySA v 0.3.' Dummy load tinySA commonly used configuration. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. I gave the signal generator a go and took a look at its output with my Keysight DSOX1102G. Right tool for the right job and all that. I would definitely throw over 150 to an instrument like that. What's in the Box - The TinySA Spectrum Analyzer - SMA-M Antenna 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. ), On the SA RF board (the one behind the control bd.) To: tinysa@groups.io. PE4302 attenuator module (eBay) ( ?? ) The . Then, flash firmware using dfu-util via USB. Satisfied with the insides, I moved on to the First Steps as listed in the video below, to get acquainted with the device. Menu structure is here. the Files area of the tinysa@groups.io group. Well worth the watch if you want to know about the device, see it compared to some heavy iron on the bench, see how and why it is used, and get a fel for the good, the bad, and the ugly. (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". Cut the track on top, leading to pin SIX of connector JP1. Significantly better bandwidth and a lower noise floor ~100dB for the frequency range spec. You can support the continued development of the tinySA by donating. worth of made in CN. Tap DISPLAY, CALC, MAX HOLD, or DISPLAY, CALC, MIN HOLD to use these functions. R23, 24, 11, 18, 19 & 20 need to be fitted as either smd or axial parts. 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. Below: The "RF module". But all the real spectrum analyzers Ive used are designed to allow time domain measurements. The new topic will begin with this message.
The document contains many screen captures of example measurements. .
June 23rd, 2020: NOTE:- Erik's tinySA original design is for an approximate upper limit of 150MHz and the input Low Pass Filter (LPF) was designed for that range. Install cross tools and firmware updating tool. I dont think Erik is a Chinese name :) If you dont want it made in China offer him a better deal. That 28.8 MHz means theres plenty of aliasing for low band stuff, and the 8 bits limits the dynamic range. Some were serious, within the dynamic range and frequency range. But after learning how to establish if a company can be trusted or not, I now have excellent parts for a very low price. The output side of the TinySA can also be used as a signal generator. July 8th Schematics and Menu structure updated. These parts are best fitted using smd components on the rear of the pcb. Groups.io, tinysa@groups.io Notification
