Control Fields for CDMA Measurements
Meas Order
This field is displayed in the Code Domain Analyzer, IS-2000. The
Measurement Order is the way in which the Walsh channels are shown
on the screen. Select
Measurement Order is the way in which the Walsh channels are shown

Bit Reversed
to show channels grouped
according to their Walsh order. Select

Measurement
This field controls the type of code domain measurement to make. In
IS-95 only mode, this includes power, fast power, timing, or phase. In
IS-2000 mode, this includes power, fast power, power and noise,
complex power, and fast power synchronization.

It also controls the measurement mode (single or continuous):
•
Single
is used when you want to make one measurement. You must
select the
Arm Meas
function of the
Analyzer
field before a
measurement can be made.
•
Cont
is used to continuously make measurements. Measurements
are automatically re-armed after each measurement.

Num Avgs
The number of averages determines how many measurements are
averaged when measuring fast power. Averaging reduces measurement
speed.
