CDMA Measurements - Screens and Control Fields
Control Fields for CDMA Measurements
Controls
Code domain analyzer settings are arranged into several menus that
are accessed using the Controls field. The control groups are:
• Main accesses the RF In/Ant, Tune Freq (or RF Channel),
Measurement, and Analyzer fields.
• Marker controls the marker to look at the level of individual Walsh
channels.
• Trigger accesses the trigger controls: Qual Event and Trig Event.
• Aux accesses the Threshold and Meas Intvl fields. In IS-2000
mode, Aux also accesses Meas Order .
• Gain lets you alter the gain Gain into the CDMA analyzer while
reading the ADCfs value. The attenuation can also be changed Input
Atten
• PN Setup accesses the PN Offset, PN Incrment, and Find PN fields.
• Reference, only in IS-2000 mode, accesses the CD pwr unit and
Chn Pwr Cal fields. CD pwr unit allows you to specify either
absolute or relative values for power measurements.
• FP Setup accesses the offset transfer and number of averages fields
used to make fast power measurements.
• CD Setup, in IS-95 only, accesses the CD pwr unit, Chn Pwr Cal,
and ChPwr fields. CD pwr unit allows you to choose either relative or
absolute power measurements.
Many of these controls are duplicates of those found on the CDMA
ANALYZER and CDMA GENERATOR screens.
