Will your input channel back to the developer would you consider doing a short "How to update Firmware" piece for the Nano and Tiny? I've seen quite a bit of confusion in some of the threads elsewhere and frankly I'm not 100% sure of the process. Anyway, just a thought...have a great holiday weekend!

If you find the sweep slow you can try the DISPLAY/SWEEP SETTINGS/FAST. It reduces the level of frequency detail a bit in exchange for faster sweeping.

-109dBm is pretty darn good for resolution of power. Older analyzers have problem resolving below -100dBm. The Motorola R2001 D/HS does not resolve below -110dBm on mine. My 9824 goes down to -125dBm before it fails. The IFR 1200/S fails at - 105dBm.

Great videos! Will you be doing one on the ‘Waterfall’ function? Would really like to use the ‘tinySA’, somehow, with an external preamp to see activity on ‘Ham Band’ segments. Thank you on your efforts!

For actual power, I input my signal directly into the HIGH port, at a predetermined level (-50dBm), and then select that , and it has shown positive results doing it that way, then the long method. I set reference level to -10, and 10dB/div. RBW is auto, and shows 336 kHz, scan speed is 105mS. I am changing the reference level, as the noise floor is too high for my liking. I get good dynamic range down to -102dBm. Lowering my reference level to -20, my dynamic range goes up, slightly, but detection sensitivity increases just enough, but also raises the noise floor by 10dB, which is no big deal, especially when the dynamic range goes up. I decided to save this setup as my startup.

I measure the TinySA noise figure as 24dB at 110MHz.

Again with the blurry back to the camera...

His last couple of videos have been like this, and you miss seeing a lot of what he is talking about, making it useless to watch!

[@sv_gravity]

Don’t block camera please, so painful to watch.
