It is possible to directly control RF Inhibit and Transmitter On/Off
via the small checkboxes under the "Transmit Control" section.
The desired attenuation level may be set by clicking in the box
next to "dB" and typing the desired level. Alternatively, the up
and down arrows to the right of the box may be adjusted.
The Constant Power mode may be selected by clicking the small
check box under the "Constant Pwr" section. If it is selected, the
amplifier will change the attenuator setting to maintain the power
level indicated in the "Lvl:" control box if the input drive to the
amplifier changes.
The "Summary Status" section indicates the current condition of
the Amplifier, whether it is in Standby, Transmitting, or if there is a
Summary Fault Condition. It also indicates whether the amplifier
is in local or remote control mode.
If the amplifier is showing a summary fault, the condition causing
the fault is indicated in the "Fault Status" window.
The "RF Power Alarms" window contains settings for Forward
Power Over, Forward Power Under, and Reverse Power Over
conditions. Each of these conditions may be selected to fault,
alarm, or be disregarded by the amplifier. Alarms do not affect
the operation of the amplifier, but when the limits are exceeded
