National Stock Number:
5985-01-273-9822

Federal Supply Class:
5985

National Item Identification Number:
012739822

Description:
ATTENUATOR,VARIABLE

Detail:
A device for reducing the strength of an alternating current signal either continuously or in steps, without causing appreciable signal distortion, by maintaining substantially constant output and/or input impedance match. Continuously variable resistive devices must consist of at least two sections or one section with at least two rotating contacts. The item must have an overall attenuation rating. Includes tandem mounted variable resistors designed to function as an attenuator but whose terminals are not connected. See also RESISTOR, VAIABLE (as modified).
