Key Features

• RF input leveling circuit protects against overdrive by limiting input to approximately 0 dBm


• Over-temperature protection removes DC voltage from RF stages upon cooling blockage or fan failure


• Front-panel gain control for convenient output adjustment


• Digital display indicates operational status and fault conditions


• Switching power supplies with built-in AC circuit breaker


• Both local (front-panel) and remote control via IEEE-488 (GPIB) and RS-232

Typical Applications

• Driver amplifier for wireless and communication component testing


• EMC testing where undistorted modulation envelopes are critical


• Bench-top RF measurements requiring instantaneous wideband coverage

Compatibility & Integration Remote control and monitoring via IEEE-488 (GPIB) or RS-232 interfaces enable integration into automated test systems. Benchtop cabinet and rack-mountable configurations support flexible laboratory and production test setups.
