Fields

Notch Coupl

This field selects if the Notch Freq setting of the AF ANALYZER screen is coupled to the AF Gen1 Freq setting. When set to None, the notch filter and AF Generator 1 do not interact. When set to AFGen1 (coupled), the settings track each other unless the AF Generator’s frequency is set outside the 300 Hz to 10 kHz limits of the notch filter

GPIB Example

“DISP CGP;CDMA:GPOWer:NAVG 100”

displays the CDMA Gated Power screen and sets the Averages field to 100 aver- ages.

When a mobile station is operating in variable (eighth-rate) data rate transmission mode, the RF power is gated on during randomized 1.25 ms periods. During a CDMA Gated Power measurement the Test Set analyzes an ensemble of gated-on periods, referred to as power control groups. The number of power control groups used to calculate an ensemble average is set in the Averages field.

Num of Bits

This field lists the total number of bits displayed. This number is dependent on Data Rate of the signal being decoded, the Gate Time of the decoder, and the size of the decoder’s data buffer.

1584 bits for decoding Reverse Voice Channel (RVC) data streams.

1583 bits for decoding Reverse Control Channel (RECC) data streams.

This measurement is not available for NAMPS-NTACS RVC decoding.

Operating Considerations

The buffer has a maximum capacity of:
