NOTE
Transmit only for as long as needed to take the measurement, then immediately disable the
transmission.
9.
Compare the wattmeter reading with the target RF output power range of
11.8 – 20.0 watts.
10.
Record the wattmeter reading for RF output power into the dummy load, or take remedial action and
measure the output again:
•
If the wattmeter reading is within the range,
record the measured value in the appropriate
space on the data collection form near the end of this manual.
•
If the wattmeter reading is outside the range,
verify the radio’s power supply voltage (i.e.,
battery voltage) is within the specified range, recheck all connections and measure the RF output
power again. If this fails to produce a reading within the range, replace it and repeat this
procedure.
16.4 TESTING WITH THE ANTENNA
The radio must be set to OTP mode (see Section 16.1) to perform the following tests. It is recommended
that a test channel be allocated for this testing; otherwise, interference with network users tuned to the
channel on which the radio is transmitting may occur.
Also, observe the safety information presented
in Section 1 (page 5) of this manual!
1.
Connect the radio’s antenna connector to the wattmeter and antenna as shown in Figure 16-1.
2.
If necessary, apply power to the radio, turn it on, and set it to OTP mode.
3.
Set the radio to a test channel, if available.
4.
Position the wattmeter’s slug to measure forward RF output power. Rotate it if necessary. The arrow
on the face of the slug must point away from the radio and towards the antenna for forward power
measurements.
5.
Using the Full-Data I/O Option Cable 1000022242-0001 and Serial Programming Cable
MAMROS0055 (or equivalent), connect the radio’s serial port to the Personal Computer’s COM1
serial port. The Serial Programming Cable is a standard modem-type serial interface cable.
6.
At the computer, start the terminal application (e.g., HyperTerminal) and verify its configuration as
listed in Table 16-1.
7.
Measure the radio’s forward RF output power into the antenna by typing these commands. Send the
commands in the order presented.
^8
— puts the radio into 100% duty cycle test mode
^W
— causes the radio to transmit
^X
— causes the radio to terminate transmissions
atz9
— causes the radio to reboot
NOTE
Transmit only for as long as needed to take the measurement, then immediately disable the
transmission.
8.
Compare the wattmeter reading with the target RF output power range of
11.8 – 20.0 watts.
