Programmable Rotary Vane Attenuators

The attenuators small compact size incorporates both the electronic controller and the microwave components. The unit operates from a single +24 Volt DC source or with an optional adapter. Attenuation range is from 0 to 70 dB in .01 dB steps from 0 to 70 dB.

A digital readout is provided on the front panel to display attenuation settings. USB & GPIB interface available. Tested to over 1 million cycles. New company proprietary internal absorbing material that will handle high power levels and yield low insertion loss and mode free operation to 70 dB attenuation levels
