of
control.
ALC Switch
(Option)
The optional Automatic Leveling Control (ALC) is a feature, which
selects the method for leveling, either internal, external or manual.
Power ON/OFF
The Power On/Off switch is a circuit breaker that is used as an
On/Off switch as well as a circuit protection device. This switch
turns the driver either on or off.
Control Level Adjust Knob The optional Level Adjust control is a ten-turn pot, which allows a
(Option)
minimum of a 30 dB range of gain. Turning the control Counter
Clockwise (CW) produces a minimum gain.
Important Note:
If the amplifier is not equipped with this option, the
display will still indicate a GAIN percentage (refer to Figure 5.0). This
percentage indication is still controlled by Level Adjust Control but the
both the Level Adjust Control and the corresponding GAIN percentage
indication has no effect on the amplifier gain.
FLT/RST
The Reset/Fault (FLT/RST) is a reset switch that resets the fault
indication. If a fault indication is present, the fault indication can
remove the by depressing this switch.
OPR/STB
The Operate/Standby (OPR/STB) switch which when the switch is set
in the Standby mode, the Power Supply is turned off to the amplifier
circuitry. When set in the Operate mode, the Power Supply delivers
voltage to the amplifier circuitry.
BAND 1/BAND 2
The Band 1/Band 2 (B1/B2) switches the frequency bands of operation.
This switch allows frequency band switching without changing the RF
Output connections. The Band 1 frequency range is 10 kHz - 220 MHz
with Band 2 frequency range being 200 MHz - 1000 MHz.
