Portable TinySA Spectrum Analyzer, SEESII Upgraded V0.3.1 Tiny Frequency Analyzer with Antenna SMA Male to UHF Female Cables, 100kHz to 960MHz MF/HF/VHF UHF Input, 2.8'' Touchscreen Signal Generator

Perfect for testing your rig. Do scan the QR code for the operating manual. This is not a toy. It is a true diagnostic tool so you must know a few things about RF Spectrum Analyzers. Also pick up a good -40 to -50dB attenuator along with this Tiny SA or you stand a good to great chance of releasing the magic smoke from within. Google “Am I Testing my Baofeng Radios Wrong” on YouTube for an excellent tutorial on this great piece of test equipment.

Good price. I am still learning how to use this TinySA and have been watching YouTube training videos online. Many of the videos are very good. I plan to connect this to my PC with WinSpectrum for larger images and the option to save, and/or print the screenshot. For my purposes -- this is a great price, and it will do everything that I want to do.

Nice Analyzer, pretty easy to understand and use for simple testing remotely. Had one problem small antenna broke right off the bat when I went to turn it up on the hinge, would like a replacement

The TinySA works just fine! And so far in testing, the accuracy of this device is not to bad. First thing, an ACTUAL instruction manual would have been really nice. There is no documentation at all on how to operate the TinySA. Luckily there are several YouTube vids out there to help you along.. The menu IS a bit confusing.... There is a lot of back and fourth in the menu to set the parameters you desire. Once again, nothing is clearly explained. The “LISTEN” feature seems to be disabled, this allows you to listen in on the frequency being monitored. I don’t even think there is an actual speaker in this unit. This is my MAJOR DISAPPOINTMENT! As this feature would have been very handy from time to time. When doing the SELF TEST of CALIBRATION, the high and low ports must be connected together with the supplied jumper cable!!! If you do not follow this procedure, the unit will fail the test and not calibrate correctly. For the price, it’s definitely a great unit and worth every penny....... Just watch the videos on how to use and setup the TinySA, as I stated..... It is a bit confusing to operate.

For the price you can hardly beat this little gem. It is very handy and is accurate enough for many applications. I also use a Agilent Field Fox so I am accustomed to a high end units accuracy and flexibility but this little unit is really nice to have for interference hunting, signal sweeps and relative signal strength comparisons.

Anuncia más de lo que es.

This item isn't exactly a toy, but it's severely limited and I recommend you buy one of the higher-end models. It's obviously very tiny, with a small screen - but that actually isn't a serious limitation. The screen is sufficiently high resolution to show a lot of useful information. However, it is a resistive touchscreen and the UI elements are very small and mostly stacked at the edge of the screen, which makes pressing them with a finger difficult - a stylus is almost mandatory. You CAN operate it with a fingernail, and there is a 3-way rocker switch (left/right/click) that can emulate the touchscreen functions, but the switch is quite flaky. Overall not physically easy to use. The visual UI is fairly easy to understand and pretty well laid out. This model doesn't have a microSD (TF) slot, nor does it have the capability to save screenshots on-device. Connected to a PC, it appears as a serial port - there is Windows software available to control it, and you could save screenshots from that software. The frequency sweep rate is slow and could easily cause you to miss Tx artifacts. The photo I shared shows a 315MHz Buick keyfob transmitting - I configured the spectrum analyzer to 315MHz center frequency, 1MHz span. This item is useful for things like a quick-look scan to verify that a device is transmitting, but it is not a precision measurement instrument. It also has absolutely no documentation, so you'll have to figure out what all the options do (some of them are far from obvious).

great little spectrum analyzer for the price
