Table A-5: Procedure to Test MCC–DO Packet Error Rate

Step Action

14 Enter the command to receive the PER measurements results:

rl_test 1 60 dflt dflt dflt dflt dflt dflt dflt dflt dflt dflt dflt dflt dflt dflt

this will set the MCC–DO to measure the PER with following parameters:

S Perform PER Test at 9.6 KBPS

S Duration 60 seconds

S DataOffsetNominal dflt=0dB

S DataOffset9k6 dflt=0dB

S DataOffset19k2 dflt=0dB

S DataOffset38k4 dflt=0dB

S DataOffset76k8 dflt=0dB

S DataOffset153k6 dflt=0dB

S MacIndex dflt=5

S FrameOffset dflt=0

S DRCGating dflt=0 Continuous transmission

S DRCLength dflt = 0

S DRCCover dflt = 1

S UATI dflt = 0x1234ABCD

S AckChannelGain dflt=0dB

S DRCChannelGain dflt=3dB

15 Read the results (after 1 minute) and calculate the PER value from the MCC–DO mmi result screen:

Compute PER using the outcome of the rl_test

PER = (expect–total+invalid) /expect

Example output:

Reverse Link Test has completed

Reverse Link Test OK MODEM#1

pattern = 1 (9.6 kbps)

expect = xxx

total = xxx

invalid = xxx

16 Receiver sensitivity is below –121.2 dBm at a signal rate of 9.6 kbps.

Read the value of the PER. PER is less than 0.01 (1%)
