MEASURE
Accesses menu keys that allow you to make Monitor Spectrum and EVM
measurements.
Monitor
Display the frequency-domain spectrum of the transmit or receive channel for the
Spectrum
selected device (mobile or base station). The channel presets are standard specific.
EVM
Error Vector Magnitude (EVM) displays the I/Q Measured Polar Vector trace of
your current signal, and also displays numeric results for the following
measurements:
