CDMA Measurements - Screens and Control Fields
Control Fields for CDMA Measurements
ACP Offset
This field designates the frequency offset from the center frequency at
which the ACP measurement is made in the adjacent channels. Valid
values are 100 kHz to 3 MHz.
This field is displayed only when the ACP measurement is selected.
Screens on which this field is present
CDMA ANALYZER
ADCfs or ADC FS
ADCfs indicates how close the measured power level is to the maximum
allowed input level for the analyzer’s Analog-to-Digital Converter
(ADC). This level is affected by the Gain setting on the CODE DOM
screen, the Input Atten, Gain, and, Pwr Gain settings on the CDMA
ANALYZER screen, and the RF level of the signal connected to the Test
Set.
For best measurement performance, ADCfs should be between -1.0 and
-10 dB. The measurement will be aborted if ADCfs goes above 0.5 dB.
Measurement accuracy may be degraded if ADCfs goes below -10 dB.

CODE DOM (Code Domain Analyze screen: gain controls menu)
CDMA ANALYZER (ADC FS)
CDMA GENERATOR (ADC FS)
Amplitude
This field sets the output level of the RF generator to the RF IN/OUT or
DUPLEX OUT port. Use the DUPLEX OUT port for signal levels
greater than -26 dBm.
