Now that you have a service option 002 call
connected, you are ready to make parametric
receiver and transmitter measurements. To
perform receiver measurements:
1.Go to the RX Test screen
2.Notice that the RX Test screen also has call
status indicators that show if the call is still
connected and if the call is a service option
002 call.
3.The parameter used to evaluate CDMA
receiver quality is frame-error-rate. To setup a
FER measurement with the HP 8924C, you
need to enter three parameters: Max Frames,
Confidence, and FER Spec.
4.Enter 10,000 into the Max frames field. This
sets an upper bound to the time limit of the
test.

•Place the cursor at the "Cont" feld
under Meas Cntl
•Push the Knob
5.Enter 95% into the Confidence field. This
field sets the desired confidence limit for the
test. If confidence limit testing is not desired,
you can turn this field off. In that case, the
FET test will run until the number of frames
tested reaches the value entered into the Max
Frames field.
6.Enter 0.5% into the FER spec field. This field
sets the desired FER specification to test to.
7.Make sure that the Display Interim Results
field is set to yes.
8.Use the knob to place the cursor in front of the
Arm field. Press the knob to start the measure-
ment.
