TEST_04 CP Speech Quality
TEST_04 CP Speech Quality
Description This test allows you to listen to the mobile station’s speech quality. The
HP/Agilent 8922 demodulates your voice from the mobile station and
routes the data through a channel decoder. After a one second delay, the
data is routed through a channel coder, and transmitted using 0.3
GMSK modulation on an RF carrier to the mobile station.
This is a qualitative test on the speech quality. After listening to the
speech quality, you are prompted to pass or fail the speech quality test.
The decision is displayed both on the screen and the printout.
