ACP Cal
This field calibrates the ACP measurement for the current RF analyzer
frequency at the selected frequency offset (ACP Offset) and filter
bandwidth (ACP Fltr BW).
This field is displayed only when the ACP measurement is selected.
NOTE
You must always remove power at the ANT IN or RF IN/OUT connector
before calibrating adjacent channel power to ensure accurate
calibration.
Operating Considerations
The Test Set can memorize approximately 16 sets of ACP calibration
data. If calibration data does not exist for a given channel and offset
setting, the following message will be displayed:
ACP UNCAL: No Freq or ACP Offset cal. Start ACP Cal.
To clear this message, select the ACP Cal field to start the calibration.
When the calibration is finished, the message will be gone.

ACP Fltr BW
This field designates the filter bandwidth around the adjacent channels
at which the measurements are made. Valid values are 10 kHz to 1.23
MHz with 100 Hz resolution.
This field is displayed only when the ACP measurement is selected.
Operating Considerations
Power is only measured with bandwidths up to 100 kHz. If a wider
bandwidth is specified, the power in the first 100 kHz is measured and
used to calculate the power in the total specified bandwidth.
