SECTION 4: FACTORY TEST PROCEDURE
M64450G25-FCCRpt.doc Page 31
Step 3 Adjust Receiver 2, as follows:
- Connect an RF cable from the Service Monitor’s “RF Out” port to the antenna
port of Receiver 2
- Observe the Service Monitor while adjusting CV1 for minimum distortion –
Distortion must read 3.0% or less
- Record the distortion on the Tune and Align Data Sheet
Data Quality and Message Success Rate
Perform the following steps to adjust receiver data quality and Message Success Rate (MSR):
Step 1 Connect the base station to an IPNC via SLIP cable (an Ethernet connection will be
used during Message Success Rate Testing).
Step 2 Connect a mobile radio with known good transmitter data quality in the test set up.
Allow the mobile radio to connect to the base station.
Step 3 Run IPLinkView or ping the mobile radio from the IPNC.
Step 4 Set the uplink RSSI at -93 +/- 3dBm.
Step 5 Connect the mobile test setup receive cable to each of the two (2) receivers in turn.
Step 6 On each receiver, run a minimum of 50 packets in IPLinkView or 50 pings.

The Data Quality of each receiver must average at least 220 over 50
contiguous samples.
Step 7 For Receiver 1, if necessary adjust CV8 slightly to improve Data Quality.
Step 8 For Receiver 2, if necessary adjust CV7 slightly to improve Data Quality.
Step 9 Calculate the Message Success Rate (MSR) over the 50 consecutive packets on
each of the receivers.

The MSR shall be greater than 94%. If MSR does not meet 94% proceed
with Hardware Time Verification for trouble shooting.
Step 10 Record the Data Quality and the MSR on the Tune and Align Data Sheet.
