1. GENERAL INFORMATION
1.1 GENERAL DESCRIPTION
The Model 800A3B is a self-contained, air-cooled, broadband, completely solid state Radio Frequency (RF)
amplifier designed for applications where instantaneous bandwidth and high gain are required. Push-pull
circuitry is utilized in all high-power stages to minimize distortion and improve stability. The Model
800A3B, when used with a RF sweep generator, will provide a minimum of 800 watts of swept power
covering the frequency range from .01 to 3MHz. The Model 800A3B is housed in a single stylish
contemporary equipment cabinet.
Special features incorporated into the Model 800A3B include the following:
• A Digital Control Panel (DCP) that allows both local and remote (via a computer interface) control of
the amplifier (including adjustment of the amplifier’s RF Gain) and provides graphical displays of the
amplifier’s Forward and Reflected power levels.
•
RF output level protection.
•
An internal RF detector , which provides an output for use in self-testing or operational modes.
•
A General Purpose Interface Bus (GPIB)/IEEE-488.2 interface for remote control of the amplifier’s
operating functions.
•
RS232 serial communications for remote control.
•
Fiber Optic Communications port
for remote control.
• USB Communication port for remote control.
• Ethernet Communications port for remote control.
•
Protection is provided by DC current limiting, over-current, under-current, and over-temperature shut
down and RF power limiting.
•
Housed in a stylish contemporary equipment cabinet , the Model 800A3B provides readily available
RF power for typical applications such as RF susceptibility testing, particle accelerators, plasma
generation, transducer testing, and use as a driver for higher power amplifiers.
