SECTION 3: FACTORY TEST PROCEDURE

Power Setting
Perform the following steps to adjust the transmit power control:
Step 1 Attach a power attenuator to the transmit port of the radio.
Step 2 Using the x=2000,19 command of IPMessage, and while monitoring the transmit power level
on the HP communications test set, check the level of the transmit power. Using IPMessage
set the power setting to txpower=0. The radio should have an output power level of
approximately 1 mW. Record this value on the Test Data Sheet.
Step 3 Using IPMessage send the txpower= command to increase the power level settings until 20
Watts of output power is obtained. Record this value on the Test Data Sheet. Note that
values on the table are to plot the codes vs. power output. The 20-Watt setting can be a
code not on the table. Adjust txpower until the code is found that does not exceed 20.0
Watts. Record this value on the Test Data Sheet.
 Do not to exceed 20 Watts of output power, as this may reduce the life of the amplifier.
Receive Data
Perform the following steps to verify the receive data performance:
Step 1 Using the DOS ping command on the PC connected to the radio, ping the network controller
to generate uplink and downlink data messages. The following command will generate one
Hundred 500 character messages:
>;Ping 192.168.3.3 -n 100 -l 500
Step 2 Observe the data quality readings on the IPMessage window of the PC connected to the
radio using the V (for Verbose) command in the IPMessage program. With the mobile radio's
antenna connected to receiver 1, verify the received data quality readings are consistently
248s. Data quality readings should also be verified at the base station using the V command
on the Hyperterminal window.
Step 3 Verify receiver 2 data quality readings are also consistently 240 to 248s by changing the
antenna from receiver 1 port to receiver 2 port. In this manner both uplink and downlink data
quality can be verified. Record this data on the Test Data Sheet.
Final Test
A final test must
be performed prior to shipping the IPM8 mobile radio to the customer. This final test will
verify that the timing characteristics are correct and that both transmit and receive data quality readings
are consistently high.
Perform the following steps for the final test:
Step 1 Attach the 40dB 100-Watt power attenuator to the transmit port of the radio.
Step 2 Program the radio for full power operation. The tx power level setting can be found in the
radio's Test Data Sheet.
 The setting must not to exceed 20 Watts.
