1. GENERAL INFORMATION
1.1 GENERAL DESCRIPTION
The Model 350AH1A is a self-contained, air-cooled, broadband, solid–state, extended range audio amplifier
designed for applications where instantaneous bandwidth and high gain are required. The Model 350AH1A,
when used with a RF sweep generator, will provide up to 350 watts of swept power covering the frequency
range from 10kHz to 1MHz. The Model 350AH1A is housed in a single stylish contemporary equipment
cabinet.
Special features incorporated into the Model 350AH1A 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 voltage and current output levels.
•
Output level protection
•
An internal voltage and current detector
•
Output phase control, 0° or 180° shift
•
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
• USB Communication port for remote control
• Ethernet Communications port for remote control
•
Protection is provided by DC current limiting, over-temperature shut down and output current limiting.
•
Housed in a stylish contemporary equipment cabinet , the Model 350AH1A provides readily available
RF power for typical applications such as RF susceptibility testing and magnetic field generation.
