Cheap Spectrum Analyzer LT-DZ 35-4400M - YouTube The Keysight N9320B spectrum analyzer is a portable, swept spectrum analyzer with a frequency range of 9 kHz to 3.0 GHz. Your oscilloscope is measuring power, not voltage like a real oscilloscope. But this just throws a dump of all the registers up on the screen and locks the thing up. First Impressions A caveat: I'm by no means an expert on spectrum analyzers.

There is even a branch that is open source (last I knew) now called the simpleSA that is based off the original tinySA design. Those products are cheap and also crappier than more expensive products. 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. With this in mind, one has to be very careful with doing business with companies over there. The Ultra version brings enhancements to the frequency range, signal . It really depends on what you want to use them for. A waterfall display is being looked at also. Erik's (PD0EK) Github page gives more information. . Description: TINYSA USER MANUAL, FOR PRINTER. So, there are more companies in China who will provide bad stuff, simply because there are many more companies there. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. There are several numbers of great companion PC tools from third-party.

and from what i have learned so far watching folks put the tinysa up against lab quality spectrum analyzers, the tinysa is good enough for the girls i run with! This thing is obviously a NanoVNA hardware, the labels are painted a bit differently and its running an entire new software. But, I am very tired of comments about technology made in china or people who insinuate things are not good because of chinese production. . https://tinysa.org/wiki/pmwiki.php?n=Main.MenuTree. Using the Menu's, select the Panadapter mode then set the centre frequency and sweep width. 2. A second option is a PDF version of the wiki, which allows for easier reading for some people, .

By enabling the ultra mode you acknowledge that you understand and agree with the limitations of the ultra mode. incorporated the required changes in a V2.0 version of the "simpleSA" boards in future. Signal Generator with sine wave output between 0.1-800MHz or square wave up to 4.4GHz or rf test signal output up to 5.3GHz when not used as Spectrum Analyzer. A tag already exists with the provided branch name. 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. Briefly, the tracking generator has an oscillator which tracks that of the SA as it sweeps the selected band. July 6 (the upper frequency limit AND Si4342 module issues.). The Ultra version brings enhancements to the frequency range, signal generator range, bandpass filter range as well as an optional 20dB LNA, and a larger 4 inch color display. Shakoor Baba wrote a comment on TAS5825M I2S Audio Amp. Anyone familiar with the NanoVNA, a small but full-featured vector network analyzer that weve featured a few times on these pages, will see a strong family resemblance between it and the tinySA, both in the hardware and the software. This board is mounted directly behind the Control board. Find here links to an article I wrote a month ago for the Danish HAM magazine OZ which I have now translated to English and German language.

There is another application specific to the TinySA here, appropriately named tinySA: http://athome.kaashoek.com/tinySA/Windows/, As noted here: https://tinysa.org/wiki/pmwiki.php?n=Main.PCSW. If new to smd work, some patience may also be required ! There are always companies who trick people. The original software didn't support an in-built display but used a PC to show the scans. Updated for Software V2.9, 12th July Will need to be updated as other features have been added by Dave, M0WID. Hi.. Im having trouble exporting a usable CSV for Shures wireless workbench.. do you have any solutions or links that would explain how to go about this? Satisfied with the insides, I moved on to the First Steps as listed in the video below, to get acquainted with the device. Especially considering the low cost. Below that the unit works great. The ESP32 by the way, can be programmed using the Arduino IDE environment. By: Eduardo Alonso <ea3ghs@.>.

Are you sure you wish to delete this message from the message archives of tinysa@groups.io? The other end of the resistor wires go though JP5 and connect to the Attenuator module on the other side. MicroSD card slot for storing measurements, settings and screen captures. Note the provision for extensive shielding. Posts from new users require approval from the moderators. Will need to be updated as other features have been added by Dave, M0WID. 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. 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. Selectable manual and automatic input attenuation between 0dB and 31dB in 1 dB steps When the steel was check in a lab it wasnt even good enough to be used as rebar. These pages reflect FW version 1.3507 or later.

Are you sure you wish to repost this message?

Mirror suppression is limited to 30dB. Nobody expects a low NF for a spectrum analyzer, so thats not a big deal. No info is available here for that. VNA let you look at the transfer function of a circuit over frequency. (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". (Pictures may not show the mods detailed above). ), On the SA RF board (the one behind the control bd.)

The document contains many screen captures of example measurements. July 8th Schematics and Menu structure updated. A draft copy of the V2 version Schematics are here and here. Guess what? The PE4302 module has 12k pull-downs on my module. 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. Once enabled the ultra mode stay's enabled. I decided to remove the 12k resistors from the back of the PE4302 module (6 in all) Now levels are much better and well in spec at full supply (3v3) which is to be expected with the pull-ups. V2.0 is the only current version that I have actual PCB's for.

Ive got a bunch of li-ion cells in view of me right now labelled things like 5200mAh 9900mAh etc. Please note the assembly of the three PCB's is preliminary at this point, no shielding has been fitted at this stage. Can observe signals up to 12GHz. See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. Cannot retrieve contributors at this time. Erik has done a great job of squeezing an amazing set of features out of simple hardware. Really you need an LNA.

Have you found a solution to import the data into the WWB? Now you are using a spectrum analyzer as a kind of time domain oscilloscope. 12 People liked this. A spectrum analyzer combined with a tracking generator, makes a very useful .

Obviously, $200. One of the best parts of the NanoVNA is that its released under GPL v3. The minimum RBW of the tinySA is 2.6 KHz, so its not much use for looking at the spectrum of a transmitter or oscillator near its main frequency, or the response of a narrowband filter. connector JP1, we can easily add a second RF board for the tracking function. Prefer to Read a document instead of original NANO board tinysa spectrum analyzer manual pdf is & ;. The top has a power switch and a jog control. The tinySA has features that my big SA doesnt have, although some of them can be added for a price. More info as it progresses. Virtually no wiring is required, just the DC input if it's not being run from a USB port. There is an awful lot of good companies in China. If not comfortable with this, use leaded 1/8W preferably components. 1 and 2. I didnt get it working (my aversion to Windows based software). Transfer fuction in laymans term is output vs input and is usually in S domain. I suspect many buyers just want a visual presentation of the spectrum. NEW Oct 11th 2020 BOM has been updated to better reflect the Schematics & correct SAW filter number.. Also mods for the Tracking Gen option. Dave, M0WID has also done much work on the software, using the ESP32. enthusiast. I worked with a company that purchased 6 very large drilling rigs from a Chinese supplier. The same menu offers a self-test function too, which cycles through a series of ten tests that take about 15 seconds to complete. There is a picture just below here though show how this can be done. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. NOTE:- To use the V2.0 boards in a tracking generator setup, a second "RF" board is needed from a second panel. These pictures of the V1.0 PCB give an idea of how the "simpleSA" is built.

(Comment Policy). The RTL-SDR is a receiver; there are ways to turn it into a spectrum analyzer, albeit with limited dynamic range and slow frequency scanning. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts. The RTL-SDR, along with appropriate external attenuators (and a noise source for the case of filter analysis), serves those purposes well. $7.50, 2 x Si4432 "RF" module (eBay) (2 for $5.00). We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are . Is it worth it?

The tinySA hardware has components that the NanoVNA doesnt have, and the NanoVNA has components that the tinySA doesnt have.

!! Id rather use an old b/w TV set or green monitor. They are pull-ups on the I2C bus. 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. Or you can set a specific sweep time to monitor slower changes. Thats for good reason the code behind tinySA is a fork off the NanoVNA codebase, and the main developer of NanoVNA, edy555, is a contributor to the tinySA project, which is owned by Erik Kaashoek. I think this message isn't appropriate for our group. or tinySA Ultra for any spectrum analyzer product, without written permission.

Andreas Spiess did a review of that SA. Or use a single strand from hook up wire. 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. The IMSAI Guy series is useful, but the more knowledgeable have noticed that he sometimes gives wrong information, so dont take everything there as gospel. (shown at right center of the picture below.). A very simple to build, Spectrum Analyzer, Page last updated on Are you sure you wish to repost this message? Is it asking too much to bump the screen size to 7? 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. A few weeks ago the tinySA Ultra was released. The minimum level is ~0.7 * 3v3 = 2.31v so there is a margin but not a lot. Currently, the software by the above is at Version 2.9 (July 2020) For the latest version though, see Github for M0WID. The PCB appears to use lead free solder and its easier to remove the sockets if some standard solder is first used to pre-tin the connectors. The tinySA arrived in a surprisingly nice presentation quality box with a gold-stamped logo on the top. Then a wave using cable converters for the front end. The firmware has features that require spending big bucks to add to my expensive spectrum analyzer. AUTO is the normal spectrum analyzer scanning mode, triggering is not active. is more than $50. 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. There have been plenty of spectrum analyzer projects in about 45 years.

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. Use as a Panadaptor. Kurt Poulsen.

They want to sell cheap shit, they do sell cheap shit, theyre very happy selling cheap shit. 2023 Ask Hackaday: Whats Your Tactical Tool Threshold? You can build almost arbitrarily complex virtual receivers the GNU Radio software and an RTL-SDR. The tinySA was developed in conjunction with Erik Kaashoek a respected member of the electronics community and an outstanding . 2023 Very nice to have a nice manual. Stop being triggered, it is the market position theyre trying to occupy. The Nano VNA is a great teaching tool which I have used in my Communication Systems lectures, and it can also be used effectively by radio Amateurs for antenna tuning, etc. Previously the standard tinySA was released back in 2020. I've started things off with the odd change just to get it basically working with the TinySA, it's given Erik the starter bits to continue with it. Of course it depends on the use. The dark side lies on how they treat their employees.

Welcome to the tinySAtm wiki! While there are similarities, the tinySA is NOT NanoVNA hardware. I prefer to read the PDF files on my tablet or computers. hell i could never afford an hp or other lab quality spectrum analyzers, but i can surely afford a tinysa! There is also a groups.io Group which covers this device too. Apples to oranges.

Connected to a PC via USB it becomes a PC controlled Spectrum Analyzer, Rechargeable battery allowing a minimum of at least 2 hours portable use. Learn how your comment data is processed. With the basics out of the way, I took a look at the tinySAs built-in signal generator. 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. 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.

Its a $60 piece of equipment. Are you sure you want to create this branch? This has allowed it to grow much beyond its initial limitations over time. Id submit that if these designer built these units in the US, Germany or Japan and sold them for 2x the China price, they would have a lot more happy customers who would actually could rely on the products they bought. In fact, this is the first time I've ever handled one, unless you count using the FFT functions in my digital. This is well known. A good compromise of sweep speed and band width is to be determined. 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. Sadly, try as I might I was unable to get TinySASaver running on my Ubuntu machine. But still, I thought Id give it a whirl. I recommend doing this. But its the few bad ones who give a bad reputation to all the rest.
