ALIGNMENT AND PERFORMANCE TESTS
4-2
Revised January 2001
Part No. 001-9800-501
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 -
Typical current when transmitting is 7
amperes with 15-watt models, and 11 amperes with
30-watt models. Therefore, a power supply capable of
producing that current at 13.6 volts is required.
Wattmeter/Load -
The wattmeter and dummy load
must measure and dissipate up to approximately 30
watts. For accurate power output measurement at 800
MHz, use a minimum number of connectors with a
Teflon or better dielectric. If coaxial cable is used, it
should be a minimum length of a low-loss type.
Speaker Load -
The speaker load is connected to the
1/8” phone jack on the back of the transceiver.
Computer and RPI -
The RPI is connected to the
computer and transceiver as described in Section
3.1.4. RPI, Part No. 023-9800-000 or other RPIs
(except 023-5300-000) can be used as described in the
preceding section.
4.1.3 TUNE SOFTWARE
General
The PCTune software is a Windows
®
-based
program. Minimum software and hardware require-
ments are as follows:
•
Windows
®
95 or 3.1
•
386SX or faster microprocessor
•
4 megabytes of RAM
•
3 megabytes free space available on hard drive
•
An available serial port
Software Installation
Proceed as follows to install this software:
1. Close all applications that are currently running
(other than Windows).
2. Insert the disk containing the PCTune software in
drive A: (or B:).
3. From the Windows 95 taskbar, choose RUN and
open SETUP.EXE on drive A: (or B:). Alternatively,
use File Explorer and double click SETUP.EXE.
From the Windows 3.1 Program Manager, choose
FILE > RUN and select the SETUP.EXE file on
drive A: (or B:).
4. Follow the instructions on the screen. The program
is automatically loaded on the hard drive and start-
up shortcuts or groups are created.
Starting PCTune
From Windows 95 -
Select Start in the taskbar, then
Programs > PCTune > PCTune.
From Windows 3.1 -
From the Program Manager,
open the PCTune group and then double click the
PCTune icon.
Exiting PCTune
Select File > Exit or click the “X” button on the
right end of the title bar.
4.1.4 PRELIMINARY SETUP
1. With transceiver power turned off, connect the RPI
to an unused serial port of the computer. Then
connect the RPI to the microphone jack of the trans-
ceiver (see Section 3.1.4).
2. Start the PCTune program as described in the
preceding section. If required, select the serial port
being used by selecting Options > Set Comm Port.
3. Turn transceiver power on and the green indicator
on the RPI should light. Move the selector switch on
the RPI to the other position if this indicator is
amber.
4. Follow the instructions on the screen to display the
main screen shown in Figure 4-2. Select Tuning >
Complete Tuning to automatically step through a
complete alignment or Tuning > Partial Tuning to
manually select each adjustment.
