I am getting an "ERROR during sweep" message when using NanoVNA Saver version 0.3.9.
The message states "failed reading data 1 10 times, Data outside expected valid ranges, or in an unexpected format. You can disable validation on the device settings screen".
I am using the NanoVNa to evaluate an RF amplifier sweeping the 1 MHz to 30 MHz range. The amplifier has 25 dB of gain so I am using a 30 dB attenuator between the output of the amplifier and the input to CH 1. When I run a sweep with the amplifier powered down the results get displayed with no errors, but when I power the amplifier up and run a sweep I get the error.
Any ideas?
