Revision 1
External Interlock
The External Interlock (Pin 13) must be shorted to the External
Interlock Return (Pin 11) for the amplifier to operate. Removing
the short causes an External Interlock fault and turns High
Voltage OFF.
RF Inhibit Control
RF is inhibited when RF Inhibit (Pin 12) is connected to Ground
(Pin 9 or optionally, pin 10). The amplifier inhibits RF by
removing the bias voltage to the SSA, thereby eliminating the
RF drive to the TWT.
Note
For amplifiers without SSA’s the RF inhibit function
will turn off high voltage eliminating the RF
amplification of the input signal.
The amplifier can be configured via the set-up menu on the front
panel to inhibit RF when the connection to ground is removed.
Figure 3, Front View of 15-Pin Connector (Female), shows the
pin layout and Table 1, Auxiliary Connector Pinouts lists the pin
definitions, functions, and comments for the Auxiliary Interface
Connector.
