Erik, Igor is correct.? If you accidently select the measure menu there is no way to back out of it without losing your settings.? There should either be a 'back' button (intuitive) or selecting the

This is with 0dB internal attenuation. If you increase attenuation these numbers can go up with the attenuation but do not fry the internal attenuator. With 30dB attenuation the tinySA will survive a

thanks for the reply i found on the main site that minus 30 dbm is reasonable is preferrably below ..but it does say for a short period of time 20 dbm will be ok useing the low band of the sa..once

An "official" reseller is expected to start on amazon, ebay and others, but I have no info yet which store name they will use

Hi All, These have been listed on Amazon UK.

Bernie, A lot of tinySA users have prior familiarity with the NanoVNA which uses the same DFU upgrade procedure.? The DFU mode can only be used for upgrading.? To use the tinySA from a serial

Scott, you can find the specification of the TinySA here: https://tinysa.org/wiki/pmwiki.php?n=Main.Specification It lists the maximum input power as 10dBm - anything more and you will likely fry it.

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
