Step 3

 Using 

IP

Message send the 

txpower=

 command to increase the power level settings until 30 

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 30-Watt setting can be a 
code not on the table. Adjust 

txpower

 until the code is found that does not exceed 30.0 

Watts.  Record this value on the 

Test Data Sheet

.   

 

 

 

Do not to exceed 30 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 

IP

Message window of the PC connected to the 

radio using the 

V

 (for Verbose) command in the 

IP

Message 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 M64700G25 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 40 Watts. 

 

 

Step 3

 

Attach a digital scope to the base station as described in section the next section, 

Uplink 

Hardware Timing Verification

.  Using the 

x=1400,19

 command (which will cause the radio 

to transmit 19, 1400 character messages), verify the following: 

 
 

Transmit frequency of radio is adjusted for minimum frequency error of +/- 100 Hz.
