Control Fields for CDMA Measurements
# of Frames
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.
