Transmit Power Control
Perform the following steps to adjust the transmit power control:
Step 1 Using the x=2000,n 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 Mobile Radio Performance Test Data
Sheet.
Step 2 Using IPMessage send the txpower= command to increase the power level settings until 16
Watts of output power is obtained. Record this value on the Mobile Radio Performance
Test Data Sheet. Note that values on the table are to plot the codes vs. power output. The
16-Watt setting can be a code not on the table. Adjust txpower until the code is found that
does not exceed 16.0 Watts. Record this value on the Mobile Radio Performance Test
Data Sheet.
Do not to exceed 16 Watts of output power, as this will reduce the life of the amplifier.
Receive Data
Perform the following steps to adjust the receive data:
Step 1 Attach a power attenuator to the TX port on the radio.
Step 2 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 3 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 Mobile Radio Performance Test Data
Sheet.
