The Model 250W1000B is a portable, selfcontained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Push-pull circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability.
The Model 250W1000B, when used with a sweep generator, will provide a minimum of 250 watts of RF power.
The Model 250W1000B is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier.
