While service option 001 calls are useful for the
veriÞcation of CDMA mobile functionality,
parametric tests cannot be accurately made in
this mode. The TIA IS-98A minimum perfor-
mance standard recommends that testing be
made using service option 002. In service option
002, the mobile under test demodulates the
received signal and then re-transmits this data to
the HP 8924C. This mode allow accurate
receiver performance measurements.
To mak e a service option 00 2 c all:
1.Press the END CALL front panel key to
terminate the service option 001 call.
2.Return to the CDMA Call Control screen.
3.Change the Traffic Data Mode to Service
Option 002.

5.Set Sector A's power to -90 dBm/1.23 MHz
(this value may need some adjustment for
varying cable losses - some phones with their
associate fixtures may require higher levels
due to path losses to make a phone call).
6.Press the HP 8924C's front panel CALL
button.
The HP 8924C's call status indicators should
now indicate that a call is connected. Depending
on the phone being used, either SO2 or Loop-

available is service option 03 (voice EVRC),
along with service option 09 and service option
