Its strange, my V2 and modded V2 to V2plus work fine. Last time i check impedance measure in 2-30Mhz range vs Agilent Impedance Analyzer E4990A (use H4 and V2Plus and V2Plus4) Measure laboratory

Remove them! :-))

Just one more graph, as an addition: A 100nF 100V, 1206-size SMD multilayer ceramic cap. Above 20MHz the performance of the 100nF ceramic and the 15?F tantalum are very much the same, while below

Dave, it's a lot of fun to reply to you! You challenge me, and move me to measuring more things! So now I have to dissect your answer; WHY? I accept such generalized statements only when they are

they have some other attenuators that might be more suitable (and cheaper) - you might look at the single T attenuator or at the dummy load. (I worry about a switched attenuator - if you accidentally

This is on H4 not SAA. There is no such thing as "cloned firmware" so not sure what you are refering to.

Hello, Has your presentation been "YouTubed"? Thanks, larry

Hello Klaus, how about the ojisan firmware. I have added a patch (2.8 inch LCD only) to make a screenshot with a Python program, see: https://www.rudiswiki.de/wiki9/nanoVNA-V2-ojisanFirmware 73, Rudi

You made calibration, and after you measure calibration load on this device and get 50 Om? Or you measure calibration load on different device?

Hi, which firmware have you used? I found out that the newest cloned firmwares for the SAA2 has a worse quality than older. The firmwares until Sept. 2020 are OK. Later versions are not usable. I

load measured 50.1 on my VOM as soon as I say DONE it starts is there a repair facility anywhere? Silly thing, I really liked using it for antenna analysis. sigh..

Yes. 5W is +37 dBm. This attenuator can handle 5W continuously, and its 41 dB attenuation will reduce the transmitter signal to -4 dBm. The TinySA max input power is +10 dBm with its internal

So, in theory an attenuator like this connected between a 5W transmitter and TinySA would work? http://www.qrpkits.com/attenuator.html

Need check calibration kit/RF connectors/cable If before calibration all look good, i think problem in 50 Om calibration, check it

This is what it does immediately after I save the cal data to 0 slot. Wow

ok it accepted config and all data cleared... yea So far so good.. 73 Paul

HI Roger got it into terminal mode and ran Clearconfig but its not happy w the "1234" Then what ???
