Amplifier Research SC1000M1

The Amplifier Research SC1000M1 is a self-contained RF system test controller designed for broadband signal routing and amplifier management in laboratory environments. Operating from 80 MHz to 1000 MHz, this forced-air-cooled instrument delivers 1000 Watts CW output power with 50 dB minimum gain. The SC1000M1 facilitates concurrent operation of up to three signal generators, four power amplifiers, and four RF loads, eliminating frequent cable reconfiguration across frequency-limited equipment.

It integrates forward and reverse power measurement with emissions feedback capability.
