5.1.5 Adjacent Channel Power—ACP
Adjacent Channel Power (ACP) is a measure of the power that leaks into adjacent transmit
channels. Depending on the radio standard selected from the Mode Setup menu, this
measurement can run in several different modes in order to measure different types of
signals. For more information see
“Meas Setup (Adjacent Channel Power—ACP)” on page 351.
Turns on the adjacent channel power measurement. The center frequency, reference level,
and channel bandwidth must be set by the user. The span is set according to the frequency
and bandwidth of the offsets that are on, and whether the RRC filter is on. The screen is
split and the lower window displays the absolute power in the main channel in dBm and
the power in each of the adjacent channels in both dBm and dB relative to the main
channel power. Also displayed for each offset are offset frequency and reference bandwidth.
The measurement settings may be configured by pressing
Meas Setup after ACP has been
selected. Pressing Radio Standard after Mode Setup has been selected will access all the
Radio Standards available for which this measurement can be applied. Pressing Meas
Control
allows you to pause or restart your measurement, or toggle between continuous
and single measurement mode.
