Rev A
2.3.1
RF GAIN Control
The RF GAIN control is used to adjust the input attenuator of the preamplifier-leveler module. This control
simply adjusts the output power level for a fixed input power level.
To adjust the RF Gain, press the Select button from the Main Menu and then press the RF Gain button in the
subsequent menu. Adjust the value using the adjust knob. Please note that the display panel is limited in
resolution compared to the control signals, which are generated and sent to the leveler electronics module.
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 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 500W1000C’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.
