The Amplifier Research Model 10000LP is a broadband amplifier designed for applications requiring instantaneous bandwidth, high gain, and linear, high power pulse output. It employs the latest design technology in its all-solid-state, low power stages and vacuum tube driver and final amplifiers. A continuously variable input attenuator permits the operator to adjust the output level as desired. Housed in a stylish contemporary enclosure, the model 10000LP is smaller than competitive equipment with similar power levels. The final amplifier stage is operated in a gated mode to improve efficiency. In operation, the amplifier requires a gate input pulse preceding the RF input pulse. A rear panel connector enables remote control of POWER, STANDBY, OPERATE, and PULSE functions. When connected to model CP2001 or CP3000, these functions are respectively controlled by TTL level signals or IEEE-488 bus.
