OPERATION
FRONT PANEL
STANDBY/OPERATE SWITCH
Push button toggles between standby and operate modes
POWER INDICATOR
Green:
Flashing green indicates standby mode.
Continuous green indicates operate mode
INTERLOCK INDICATOR
Yellow:
Illuminated if the external interlock (rear panel) has been activated. Amplifier will be in non operating
mode.
FAULT INDICATOR
Red:
Should the amplifier be subject to a failure in the cooling system (either by a fan failure, inadequate
air supply or excess ambient temperature) this indicator will illuminate and the amplifier gain stages
will all be turned off. This action is non-latching, so the gain stages will come on again when the
amplifier has cooled down.
LOCAL LOCKOUT INDICATOR
Yellow:
Illuminated if local lockout has been implemented by external software, Standby/operate button is
disabled.
This indicator is only present on models with the optional USB control interface
RF INPUT (depending on model)
The RF input will accept a signal from an RF generator. This input must be within the operating
frequency range of freq. An amplitude of up to 0dBm will be sufficient to saturate the amplifier.
Operation outside the specified frequency range should not be attempted, and may subject the
amplifier to undue internal stress.
RF OUTPUT (depending on model)
This connector must be suitably terminated at all times during operation. Ensure that the cable and
load are all capable of handling the power available. On no account operate the amplifier without a
proper termination or defective cables or connectors. The centre conductor of the RF output
represents a severe burn hazard to personnel.
AIR INLET
The amplifier depends upon a free air supply for cooling. Ensure that the front air inlet is not
restricted.
