SmartStep® Subsystems IEEE-488 Gain Adjustable Amplifier RS232\RS422 Up to 4 independent channels Features o o o o o o 3.4 to 4.2 GHz operation Up to 4 independent channels 50 Ohm operation 0-15 dB, 0.5 dB step programmable attenuation Output compression +15 dBm minimum Designed to interface with industry standard communication interfaces: - GPIB/IEEE-488 (HS-488 ready) - RS-232, RS-422 0-15.5 dB / 0.5 Steps 0-15.5 dB / 0.5 Steps Description This versatile subsystem contains up to 4 parallel gain controllable channels. The attenuators being used are relay based, 0-15 dB, 0.5 dB step programmable attenuators. All of the attenuators are independently controllable through the RS-422/232 or IEEE-488 control bus. 0-15.5 dB / 0.5 Steps 0-15.5 dB / 0.5 Steps Using a Rack Mounting Kit allows the unit to be easily mounted into any rack or cabinet that is designed per EIA RS-310 or MIL-STD-189.
