Chapter 4, Description of Fields

Fields

Active (annunciator)

 

 

When lit, the Active annunciator indicates the control channel of the Test Set is

 

 

turned on.

 

 

If this annunciator is lit, the base station is transmitting system parameter

 

 

overhead messages on the assigned control channel. If the annunciator is not lit,

 

 

the base station is not active.

 

 

 

NOTE:

The Test Set may still be outputting a modulated RF carrier but the Test Set’s firmware is not

 

active and no communication can occur between a mobile station and the Test Set.

 

 

The Active annunciator is not programmable.

ACP Meas

This field selects the format for displaying upper and lower adjacent channel power levels.

Ratio displays the power levels relative to the power around the center frequency (Tune Freq). Levels can be displayed in dB or as a percentage (%).

Level displays the absolute power levels in mW, W, dBm, V, mV, and dBmV.

Operating Considerations

TX Power and ACP Level can only be measured through the RF IN/OUT port. Four dashes are displayed for these measurements when the Input Port is set to Ant (ANTENNA IN).

ACP Ratio can be measured on either the ANTENNA IN or RF IN/OUT port.

For more information, refer to "How the Test Set Measures Adjacent Channel

Power (ACP)" on page 83.
