Description
The ACPMETHOD command is used to select the measurement
method for making an adjacent channel power measurement (ACP).
The selections include the analog method, peak method, two bandwidth
method, burst method and gated method.
ANALOG METHOD Continuous power integration versus
PEAK METHOD Peak power integration measurement for
394
frequency measurement Selects the analog method
which measures the power in the main and adjacent
channels assuming a continuous carrier. The rms power
of that carrier is detected using power detection. This is
done by using a video bandwidth that is much wider
than the resolution bandwidth. Then the power, not the
log of the power, of each measurement cell is added.
This method measures analog FM systems.
TDMA This method is similar to the analog
measurement used by the analog method except that
positive peak detection is used, allowing the
measurement of burst carriers. For this method, the
sweep time is set to 600 times the burst period.
