Making the Adjacent Channel Power (ACP) Measurement

Bar Graph (Total Pwr Ref) - A histogram of powers referenced to the total power

Bar Graph (PSD Ref) - A histogram of powers referenced to the mean power spectral density of the carrier in dBm/Hz

Spectrum - In the factory default condition, the frequency spectrum with the FFT sweep type is displayed with the bandwidth marker lines in the graph window. The corresponding measured data in the text window is the total integration power levels, in dBc and dBm, within the defined bandwidth as shown in the figure below.

Depending on the Meas Type setting, one of the two following displays is obtained:

Spectrum (Total Pwr Ref) - A spectrum display referenced to the total power

Spectrum (PSD Ref) - A spectrum display referenced to the mean power spectral density of the carrier in dBm/Hz

You can improve the update speed of the displayed data values by turning off the spectrum trace in Meas Setup.
