Hi,
Like the others have written, its the measured phase of the S21
measurement, and as nothing is connected between ch0 and ch1 you only see
the noise in the ch1 receiver.
It also looks like you don't have a good calibration. If there is nothing
connected to ch0 in the picture, you need to redo it.
Remember to always press reset before you start the calibration...

Hi, i just purchased a nano vna and can't seem to get it working
properly. When i ruen the unit on i get only what i can describe as noise
on the screen. When i calibrate the unit, the screen does not go blank but

not help. Am i doing something wrongbor di I have a defective unit ? See
