PN Offset Pwr Gain
PN Offset
Use this field to enter the PN sequence offset index for your base
station. Each whole offset is equal to 64 chips (= 52.08
µs). Fractional
values are rounded off, and can be entered, in increments of 0.015625
(1 chip). Once entered, this value is shared by all CDMA screens.
This value is used by the analyzer when the Even Sec In field on the
CDMA GENERATOR screen is set to Enable
.
NOTE When the Even Sec In field is set to Not, changes to the
PN Offset field have no effect on the analyzer.

Pwr Gain
This field is used to set the level into the CDMA analyzer when making
average power measurements. Levels are set in 6 dB increments. The
IF signal level is displayed as ADC FS when average power is
measured, and should be between −1.0 and −5 dB for best measurement
results.
• Auto
automatically sets the gain for an ADC FS value in the range
of −1 to −5 dB. This is the recommended mode of operation.
• Hold
lets you override the automatic setting to manually set the
gain.
This field is only displayed when an average power measurement is
selected.
