However, there are small handheld scopes available for quite reasonable prices, including some kits. The same menu offers a self-test function too, which cycles through a series of ten tests that take about 15 seconds to complete. If not shure about quality dont buy but stop Regards. The output side of the TinySA can also be used as a signal generator. To AVOID SHORTS TO THE GROUND AREA , place a small piece of insulating tape under the parts. Just link across each component in the SAW filter path. The following files have been uploaded to The other signals shown with Markers "2" & "3" are harmonics of the Cal signal. 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. An appeal to manufacturers: I understand that 2-3 screens are among the cheapest around, but please dont forget about people with less than perfect eyesight. Spectrum Analyzer Features. Download the software to put the firmware on the tinySA from here. Is it worth it? Are you sure you wish to delete this message from the message archives of tinysa@groups.io? Ask Hackaday: Whats Your Tactical Tool Threshold? There is also a groups.io Group which covers this device too. A spectrum analyzer combined with a tracking generator, makes a very useful instrument to also allow sweeping of filters and such things. 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. Below: The "RF module". For those that prefer to read a document instead of browsing a wiki, there are two options. Thank you -- 73, Bernie, VE3FWF (most typos in this message were generated by highly sophisticated auto-correction software) Other than the occasional misinformation, its overall a pretty decent set of videos. NOTE: this allows the logic levels into the PE4302 to be approx. But this just throws a dump of all the registers up on the screen and locks the thing up. You can even build your own, although a fairly complex project, if you look on the web for Scotty's web pages. [see also links below for later versions] (NOTE R15 has been removed from the original Schematic links above) Right now I have NOT released Gerber files for this V2.0 version nor the software. Color display showing max 290 scan points providing gapless covering up to the full low or high frequency range. The original used an Arduino NANO board but it was decided, in conjunction with WA2FZW & G3ZQC, to use an ESP32 board as it is much more powerful and has more memory plus in-built WiFi which is used to connect to the PC if required. A tag already exists with the provided branch name. 3 This is what the TinySA-App control screen looks like on a Windows PC. A few examples: https://www.jameco.com/z/109990013-Seeed-Studios-DSO-Nano-v3-Pocket-Size-32bit-Digital-Storage-Oscilloscope_2217393.html, https://www.banggood.com/Original-JYETech-15801K-DIY-WAVE2-DSO150-Touch-Screen-Dual-Channel-Digital-Storage-Oscilloscope-Kit-p-1417054.html, https://www.banggood.com/NEW-JYETech-13805K-DSO138-Mini-200KHz-Digital-Oscilloscope-SMD-Soldered-Version-DC3_5V-6V-With-Housing-p-1627586.html, https://www.ebay.com/itm/363543463635?LH_ItemCondition=3, https://www.banggood.com/MUSTOOL-MT8208-Intelligent-Graphical-Digital-Oscilloscope-Multimeter-2-in-1-With-2_4-Inches-Color-Screen-1MHz-Bandwidth-2_5Msps-Sampling-Rate-for-DIY-and-Electronic-Test-Upgraded-from-MT8206-p-1707883.html. Then a wave using cable converters for the front end. While I am in no w. This resolution filter is swept across the desired frequency range. 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. Description: Groups.io, tinysa@groups.io Notification . local time. ie Control PCB, std SA RF board, then optional TG pcb. Their nation therefore rightfully gets credit for having an industrial policy of selling cheap, mislabeled shit. A waterfall display is being looked at also. The code is already available on github. 100. Switchable resolution bandpass filters from 200Hz to 850kHz. the RF section. Check for non continuity with a ohm meter! The generator function can not be used as a tracking generator as you can not use the spectrum analyzer and generator functions at the same time. 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. worth of product direct from CN. Im not sure that alone would keep the pirates at bay, but its at least an attempt and its a nice touch to boot. 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 thing is obviously a NanoVNA hardware, the labels are painted a bit differently and its running an entire new software. 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. The result is that you end up being waaay out of spec again but at the Low power setting. But still, the tinySA is a nice way to take a look at what youre actually putting out into the ether, and to at least get a rough idea how clean youre operating. A good compromise of sweep speed and band width is to be determined. /tinySA-user-manual-march2021.pdf. (11th & 24th Aug, see above information) As for the needed software, that's beyond my capabilities. If new to smd work, some patience may also be required ! tinySA/Build instructions for the Tiny Spectrum Analyzer.pdf. Right tool for the right job and all that. Page last modified on March 07, 2023, at 08:00 AM, Spectrum Analyzer with two inputs, high quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz or. Please be kind and respectful to help make the comments section excellent. I worked with a company that purchased 6 very large drilling rigs from a Chinese supplier. Here are the plots comparing a bench HPF I had on hand with the Rigole and simpleSA. The RTL-SDR, along with appropriate external attenuators (and a noise source for the case of filter analysis), serves those purposes well. 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. There is no designated place on the V1 pcb. Wide tuning range, but varying circuitry afterwards. These reviews mainly deal with classical sine wave performance, with modulations such as AM, 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. To call these copies precision instruments is quite laughable. . Now you are using a spectrum analyzer as a kind of time domain oscilloscope. the RF section and the Control section. NEW March 3rd 2021 I'm unsure if Dave keeps this upto date though. PRESET loads or saves configurations. I keep many of my files in triplicate on Dropbox, Google Drive and OneDrive. You could probably modify the firmware to get some functionality, but I would guess the frontend would not be sensitive enough to be useful. Ill update as soon as I get a chance! I never noticed him talking about Chinese product quality. R25, 26, 27 are NOT on V1 pcb overlay and are currently not required. 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 . The hard work of course, is done in Erik's choice of easily available modules and of course, the software ! But I think it was around $60, and at that price Id say adding a tinySA to your toolkit is a no-brainer. Works well below -30dB so consider using with attenuation or signals of interest. The tinySA arrived in a surprisingly nice presentation quality box with a gold-stamped logo on the top. The top has a power switch and a jog control. Nice to see proof that the Baofengs arent as bad as crudgedly old HAMS want to believe. There is no designated place on the V1 pcb. Are you sure you wish to repost this message? That cuts way into the usable dynamic range. The original tinySA uses several eBay modules which can be just connected up with co-ax cables and wires and connected to the PC. This is a great time saver as your most common setup will be available whenever you cycle the power. 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 spectrum analyzer is a tool that allows users to visualize signals on the radio spectrum. Manual (0.2, 1, 3, 10, 30, 100, 300, 600 and 850 kHz), or automatic: Signal generator: . Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz. 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. A caveat: Im by no means an expert on spectrum analyzers. DISPLAY controls various aspects of how the signals are being displayed. WiFi is used to send the screen dump to a PC. 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. Well it doesnt work as a spectrum analyzer, so if thats what you need youd be out of luck. Buyer beware. I love that the tinySA is portable and runs on batteries I can take it anywhere with me! View All 7 Messages In Topic. Its actually more of a function generator, since it can not only output a nice clean sine wave on the low output between 100 kHz and 350 MHz, but it can also modulate the signal (AM, narrow FM, and wide FM) and do sweeps both across a frequency range and over amplitude. I have been buying parts from China for 20 years. @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. Building the PCB. Even on eBay, you can expect to pay between $500 and $1000 for one of these. On the TG RF board, R35 is a 0 ohm or very low value. Fit this module onto the "simpleSA" board using very short spacers (eg nuts or washers) so that the 7 connections can be made without any shorts. You can see the Menu structure below. https://tinysa.org/wiki/pmwiki.php?n=Main.MenuTree. Dave, M0WID has also done much work on the software, using the ESP32. Anyone who has used a NanoVNA will feel at home in the tinySA interface. Or use a single strand from hook up wire. Yesterday there was an auto attenuate firmware upgrade.

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. Updated for Software V2.9, 12th July Will need to be updated as other features have been added by Dave, M0WID. Get real people. I would definitely throw over 150 to an instrument like that. and the Control Section. The schematic is in two parts, Oct 12th 2020 NEW Schematics (errors etc corrected.) Minimum RBW is ~2.6KHz and input bandwidth for example. July 8th Schematics and Menu structure updated. 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. The tinySA has features that my big SA doesnt have, although some of them can be added for a price. Switching the waveform to a square wave at the same frequency did what I thought it would a big peak at the fundamental and a bunch of spurs at the odd fundamentals. What does a Spectrum Analyzer do? When the steel was check in a lab it wasnt even good enough to be used as rebar. This is what I saw with a Baofeng UV-82 radio on an HP8591E spectrum analyzer. It is always best to talk to other people who have purchased the product for their reviews. By enabling the ultra mode you acknowledge that you understand and agree with the limitations of the ultra mode. 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. It is fairly straight forward, but is not as user friendly as touch screen operation. No info is available here for that. Connected to a PC via USB it becomes a PC controlled Spectrum Analyzer Or you can set a specific sweep time to monitor slower changes. However, I would happily pay 20-30 more bucks just to have a 7 screen. There is provision in Dave's code to use the simpleSA as a Panadaptor. Its a $60 piece of equipment. Shop around, find one that meets your needs. IMSAI Guy did an updated video teardown also. Menu structure is here.
