5.22.3.5 Total Pwr Ref or PSD Ref
Displays the type of power measurement reference selected using the
Meas Type key (see
“Meas Type” on page 458).
Total Pwr Ref is the power in the carrier that is used as the reference in computing the
relative power values for the offsets. When Man is selected, this can be set by the user.
When Auto is selected, this is the measured power in the reference carrier.
PSD Ref is the mean power spectral density in the carrier that is used as the reference in
computing the relative power spectral density values for the offsets. When Man is selected,
this can be set by the user, when Auto is selected, this is the measured mean power spectral
density in the reference carrier.
