NSN 6625-00-080-7204

Electronic Frequency Converter

NSN: 6625-00-080-7204 | Model: 540B

An electronic device having frequency mixing circuits and an integral oscillator which mixes the incoming frequenc (ies) with the oscillator frequency, the resultant frequency(ies) being a combination of the two sources. Includes equipment that performs these functions at either radio or power line frequencies. Excludes items that change frequency by means of rotating equipment or rectifier and switching or keying circuitry.

Functional Description

Extends frequency measurement range of an/usm-26 & an/usm-207a into microwave range; along w/ an/usm-26 or -207a can measure frequencies up to 12.4 ghz, or w/ an external mixer 1-18 ghz; can be used w/out a frequency counter to measure frequencies below 4 ghz w/in about porm 0.5 pct; frequency is determined by zero-beating the unknown signal w/ a harmonic of an extremely stable signal generated w/in & to measure cm-77a fundamental frequency on a counter; multiplying counter readout by harmonic causing the zero-beat gives input frequency; harmonic no. Is determined from previous knowledge of input frequency or by computation; zer/-beat is displayed on internal oscilloscope
