1 10%-100% Expansion of modulation meter scale:
Pos. 10% - Full scale show 10%
Pos. 100% - Full scale show 100%
2 LPF\15KHz ON/OFF Low pass filter selector
3 DOWN Control frequency display. A momentary
pushes causes the digit to go down 10KHz
a time
4 ENTER Enters the frequency on the display into
microprocessor and memory. Once entered,
the frequency is stored until a new
frequency is entered on the front panel
even if the power is turned off for
several days
5 UP Control the display frequency in the
same way as the "DOWN" button, except
that the frequency goes up in 10KHz
steps
6 METER SWITCH Pushing the switch each time will light
on led at a time in upward direction
7 LEDS Light indicator indicated which
parameter of the exciter is being
displayed on the analog meter
8 SWR ALARM If this indicator lights, it means that
the exciter shut down to a high VSWR
condition on the output
9 REMOTE This indicator shows if the exciter is
controlled by a remote computer
10 UNLOCK This indicator will light when the VCO
is not locked to the reference
frequency. Power output will also
decrease to zero in this condition
11 METER Analog meter used to monitor the
parameters the exciter such as:
15V
+12V
+5V
