Part No. 001-7240-001
ments that are performed are shown on the eight
buttons on the left side. To perform just one adjust-
ment or perform the adjustments individually, click the
applicable button for that adjustment. Alternatively, to
have the program automatically step through all
adjustments, click the “Tune Entire Radio” button on
the top.
Power Adjust Screen
A typical adjustment screen is shown above. The
general function of the buttons in this screen are as
follows:
•
The Down, Down Fast, Up, and Up Fast buttons
change the setting.
•
The Next Data Point button selects the next
frequency or test point and the Prev Data Point
button selects the previous frequency or data point.
•
The Save Data button is clicked if the new tuning
values will be used.
•
The Exit button exits the tuning step. If the Save
Data button has not been pressed, another window is
then displayed to select if the data should be saved.
If “No” is selected, the new tune values are ignored
and the old values continue to be used.
5.4 ALIGNMENT PROCEDURE
5.4.1 TEST SETUP
Connect the test setup shown in Figure 5-1. Addi-
tional information follows on equipment in this setup.
Antenna Jack Adapter - The transceiver antenna jack
is an SMA female type. Therefore, some sort of
adapter may be required to connect test equipment to
this jack. An SMA male to BNC female adapter is
available by ordering Part No. 515-3102-060.
Test Cable - An extension test cable (see Table 1-1) is
required to operate the transceiver when it is opened.
This cable reconnects the keypad/display board to the
audio/logic board.
RF Signal Generator - When connecting the gener-
ator to the antenna jack, use at least a 6 dB pad
between the generator and transceiver. This protects
the generator if the transmitter is accidentally keyed
and also ensures that a 50-ohm load exists. The input
levels listed in the PCTune screens are at the antenna
jack, so increase the generator output accordingly.
Power Source - If a battery is used to provide trans-
ceiver power during alignment, make sure it is in good
condition and fully charged. Power output levels are
with 7.5 volts applied to the transceiver. Typical
current when transmitting at high power is 2.0 A.
Wattmeter/Load - The wattmeter and dummy load
must measure and dissipate approximately 4 watts.
Audio Generator - The audio generator is connected
to the larger (1/8”) mono phone jack of the RPI shown
in the following illustration.
Speaker Load - The speaker load is connected to the
smaller (3/32”) mono phone jack of the RPI as shown
above. This is a low level audio output that requires a
load of approximately 680 ohms.
Computer and RPI - The RPI is connected to the
computer and transceiver as described in Section 3.1.
Note that RPI, Part No. 023-9800-000 must be used.
Other RPI’s do not have the jacks required to inject
mic audio and monitor speaker audio with a computer
