OPERATORADJUSTMENTS
The operator adjustments are accessible through a slot in the cover of the RF enclosure.
These are 10-turn potentiometers VR1 through VR5 and switch SW1. Their functions are as
follows:
Ref. Des.
FunctionI Adjustment
VR1
Determines the threshold for a valid input RF power level.
VR2
Low RF power output threshold set to determine the alarm level for the LPA
signal at the Remote Monitor connector.
VR3
Sets the Forward Power Monitor (VFM) voltage at the Remote Monitor connector.
VR4
SWR threshold set to determine the alarm level for the SWR signal at the
Remote Monitor connector.
VR5
Sets the RF output power level.
SW1
Determines the method of RF output power control. The TEST position provides
regulated DC control. The OPER position provides RF feedback leveling control.
A basic understanding of RF principals is necessary before making any adjustments to the
unit. This includes the knowledge of the relationship of forward and reflected power relative to
SWR, etc. Adjustment also requires the familiarity and use of test equipment. If in doubt,
consult your distributor, dealer or the manufacturer about changes.

OPERATORADJUSTMENTS
Switch SW2, located inside the RF enclosure, is set according to the particular configuration of
each amplifier. This switch is factory set at the time of manufacture and should not be
changed. Never turn on more than one switch at any time!

The necessary adjustment procedure to change the RF power level must be done in the
sequence shown as follows:
,I
Provide a proper low-VSWR RF termination for the amplifier.
1. Place SW1 into the RUN position.
2. Apply the minimum RF drive level and adjust VR5 for nominal output power.
3. With nominal RF output, measure the voltage on pin 7 of the monitor connector (VFM)
and adjust VR3 to obtain 5 volts
4. Reduce input drive by 3 dB and adjust VR1 so the RFON signal at pin 6 of the monitor
connector goes low
5. Restore minimum drive and set the output power down 3 dB from nominal with VR5.
Adjust VR2 just until the LPWR signal at pin 9 of the monitor connector goes low.
Increase the output power to nominal with VR5 while watching for the LPWR signal to
go high.
6. With the RF drive off, disconnect the 50 U load and connect a 3:1 VSWR termination.
Turn on drive power and set to the nominal level. Adjust VR4 just until the SWR signal
at pin 8 of the monitor connector goes low.
