Monitor Spectrum

Displays the frequency-domain spectrum of the receive channel or band
for the selected device (mobile or base station). This allows you to a
quickly check that there is a signal that can be measured.

Error Vector Magnitude (EVM)

Displays the I/Q Measured Polar Vector of the received signal, and lists
both the maximum and the average values for EVM (rms), EVM (peak),
Mag Error (rms), Mag Error (peak), Phase Error (rms), Phase Error
(peak), Frequency Error, I/Q Offset and the Droop Error.
