Two basic types of Programmable Rotary Vane Attenuators, Series 620 and 621, are available. The Series 620 has been extended to include models down to 3.22 GHz. The new Series 621 models offer an additional high resolution helical readout scale offering manual control.

High Speed Operation:

Programmable Rotary Vane Attenuators are fitted with a high speed drive motor capable of re positioning the attenuator from 0 dB to 60 dB (see note 1) in less than 1.1 seconds when driven by our dedicated Control Processors.
