2.4.2
RF Output
This Type N connector is the RF output of the amplifier.
CAUTION:
Do not connect or disconnect any loads or cables from the amplifier’s RF
Output when the amplifier is in the Operate mode. Dangerous voltages
that could cause serious injury to the user exist at the RF Output when the
amplifier is under power.
2.4.3
IEEE-488, USB, and RS-232 Interfaces
The Model 800A3B’s remote interfaces allow remote control, via a computer, of all amplifier functions
(except for the Keylock Switch position) that can be controlled from the front panel. When the amplifier is in
the Remote mode (as determined by the position of the Keylock Switch), a special Remote display is shown
(see Figure 2-3). Front panel controls are deactivated, except for the Keylock Switch, which can be rotated to
LOCAL or INHIBIT in order to prevent remote control commands from being executed.
Refer to Section 2.6 for information on remote operation of the amplifier.
2.4.4
Safety Interlock Connector
The safety interlock connector interface provides for external safety switch interlocks that will prevent the
amplifier from entering or being placed in the Operate mode unless an external connection is made. A
connection between Pins 1 and 8 must be completed to operate the amplifier. A second interlock circuit
removes primary AC power from the main power supplies when it is not closed. This circuit is found on pins
10 and 14.
