Functional Description

Portable instrument capable of measuring any frequency within the range of 100 to 500 mhz w/accuracy of porm 0.001 pct. Uses heterodyne principle for determining frequency of an unknown signal; measurement is accomplished by heterdyning a known signal from the test instrument against the unknown signal. Check points are used to calibrate the instrument throughout its operating range. Used to test the following avionics systems: an/akt-18; an/ara-31; an/arc-54; an/arc-60; an/arc-73; an/arn-3 (); an/crd-4; an/trc-68; an/urr-35c; r-508/arc; r-509/arc, and t-366() /arc

Description

Meter,electrical Frequency

CAGE

80058

An instrument which measures the rate of regularly recurring variations in an electric current or voltage and is usually calibrated in hertz (cycles per second or cps). The value may be expressed by means of a pointer and calibrated dial vibrating reed or a digital read out display. For instruments which measure radio frequencies, see calibrator, frequency; and wavementer. excludes: counter electronic digital.
