2.4 INPUTS AND OUTPUTS
The input and output connectors described in the following sections are located on the unit’s front or rear panels;
refer to the Front and Rear Panel Features drawings (Figure 2-1, Figure 2-2).
2.4.1 RF Input
This Type N connector is the RF input to the amplifier. It should be connected to a RF signal generator or
sweep generator.
2.4.2 RF Output
This Type 1-5/8 EIA male 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 5000A225C’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
Located on the left side of the rear panel, as viewed from the rear, are the remote interface connectors and safety
interlock connectors. The 15-pin D-sub miniature female safety interlock connector provides two separate
interlock loops. Pins 1 and 8 are used for situations where the amplifier can be left on, but forced into
STANDBY mode. This interlock is called Inhibit Interlock. Pins 10 and 14 are used for situations that demand
the safest possible condition, with the AC power to all main circuits disconnected. This interlock is called AC
Interlock. Both loops must be closed, or jumpered, for normal operation.
