Dear Erik, There have been a lot of postings on the various nanovna groups, saa2 in particular, about static discharge damage, and adding an esd diode diodes across each input. The

For those who are using the TinySA as a bandscope and/or panadapter: how are you connecting it to your antenna without having to constantly plug and re-plug when you want to transmit or receive? Are

I have used a small rock with great success, better than my finger anyway. John VE7KKQ

Things I have used are either end (retracted) of an ink pen, my fingernail, an orange wood stick, either end of a pencil, the tip of a key, the guitar pick stylus that came with the unit, the handle

One would hope, buy you have to remember the old saying: "Nothing can be made foolproof because fools are so ingenious". 73 -Jim NU0C "Erik Kaashoek" <erik@...> wrote:

Good for you!? Spectrum analyzers are wonderful toys to have.? I have a Siglent SSA3021X spectrum analyzer here, which I really like. I also have a Siglent SDS1104X-E oscilloscope that will do FFTs

I use a variety of items as styluses, depending upon what's closest to me, but it's usually one of those shown below.? On the left is a stylus I bought at Dollar Tree for, you guessed it, a dollar.?

Not on the TinySA. But if you want a low cost solution use an SDRplay RSP1A and the free Spectrum Analyzer program that was written for it.? A little over $100 USD Roger

Thanks Jim. I believe you are correct. 2.7KHz is the lowest I have been able get. I have a DSA705 on the way. Walt Cates, WD0GOF https://wd0gof.com/Hallicrafters A majority of acceptance is not

I see in your photo that you have a cable attached to both ports and assume you are connecting the two ports together for the self test. ? Have you checked the cable to make sure that it is OK? If

No. Resolution bandwidth is determined in the main chip, and it only has a certain number of RBWs available.? The filters are implemented in firmware internal to the chip.? I think 2.7 kHz, or 3

Hello, I do not believe I have a clone, I opened the SA up, and it had the version of 3.0,not 4.0,OK. Here is what I have, during the calibration, my SA will not make it past the 4th configuration I

Wow!? What a response!? Now, it's "decisions, decisions"? lol Thanks everyone! Rick Hendricks KE0GB

I'm not aware of any way to go that far down in RBW (but I would be delighted to be proven wrong!), not to mention the waveform on the display will have a flat top that makes finding the exact peak a

Sharing some results I obtained using a GPS-disciplined oscillator (GPSDO; 1 ppb accuracy) to measure the output frequency accuracy for the TinySA. I used the heterodyne method: i.e. set the GPSDO to

Is there any way to get the RBW down to 200Hz with a center freq of 3.9MHz and a scan width of 8KHz? Keep it simple please. My TinySA is authentic and has passed all self-tests etc. Walt Cates,

not on mine

I use a piece of 1/4 inch wood dowel that I sanded down to a dull point. I also went the extra step of using some wood stain to make it pretty, but that is a personal choice. Dave

Yes full colored ARE NOT OK as I wrote on top of picture. These are not OK. 73
