Erik. I have the frequency set to start 0 and stop 200Mhz. If I select "measure" incorrectly, any of the available options will not allow me to return without disturbing the setup. Even the "off"

Thanks Herb. ?A bit confusing for the first time user. I just learned that you can use a serial terminal to connect with TinySA. ?Not sure if you need to be in regular mode ?or ?DFU mode to do

with an external ittenuator what is the maximum input the spectrum annalyzer would handle 1dbm or 2 dbm or even lower any chance could u give me a accurate reading ..also did u design this spectrum

The noise measurement page is updated https://tinysa.org/wiki/pmwiki.php?n=Main.NoiseFactor

The input power of the fundamental should be as low as possible to avoid the tinySA generating internal harmonics. But the fundamental should also be so strong the harmonics do not disappear into the

hi purchased one of thease. spectrum annalyzers are new to me still learning. what would be the maximum input power for checking harmonics ?on the tinysa? if anyone could reply that be great thanks

I will adapt the page to use two amplifiers, just like in the Keysight instructions. With one amplifier I did not see the noise increase (unless I added the input resistive termination) so the

Hi Erik, For this method of NF measurement it is important that the noise contribution of the DUT is dominant over the noise of the S.A. itself. One can easily check this in your example by powering

Bernie, v0.3 is the production hardware revision.? The beta hardware revision was v0.2. - Herb

Erik: On the TinySA flash page, when it boots, it says in bold letters “tinySA v0.3” I assume this is the version of the boot loader? -- 73, Bernie, VE3FWF (most typos in this message were

Thanks. I'm confused about terminating the input with a resistor. This increases the noise considerably. The rest seems ok

Ah, Unplug the tinySA, wait for the beep, plug in again, wait for the beep and try again. tinySA.exe may hang in a hidden state waiting in deadlock

Is terrible, my neighbours are using them. I had to put chockes over all the mains electricity cables where they enter my home, including the ground cable. Remember you can do DISPLAY/STORAGE/STORE

Try going into the Device Manager window and under View, select "show hidden devices" Then, have a look for any old STM USB or DFU devices and delete them. Now, connect the SA and let Windows detect

I have just found it works fine on my other Windows 10 PC. Same TinySA, same TinySA.exe. Odd.

Have you tried accessing the SA via a terminal, like TeraTerm? Does it work?

Thanks for clarifying the build number. It happens to me too! I don't think it's that, I have left it for over 15 minutes and nothing happens. By the way, I don't mean the port selection box isn't

Hi All, I thought you may be interested to see the Tiny SA in action when trying to trace some RF interference from a Data over Power line adaptor. The Yellow trace shows the peak hold trace with

Thank you Erik. You have a truly remarkable product. ?TinySA is a game changer. Every high school Science ?Department should purchase a TinySA. ?The product maturity is there now, What a great
