Special Features:

insertion loss 5.5db; switching tiem 5 microseconds; inptu power plus 15v DC at 150 milliamps, minus 15v DC at 75 milliamps; max input ttl low level voltage 0.8v, sunk current 1.6 milliamps; min input ttl high level voltage 2.0v, sourced current 40 microamps

Properties:

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).
