Fairchild EMC25 The EMC25 Interference Analyzer is

The EMC25 Interference Analyzer is not only an RFI receiver; it's also a programmable selective RF Voltmeter compatible with a wide variety of peripheral equipment. Additionally, the EMC25 may be used as an RFI/EMC meter, a field strength meter, and a frequency selective 2- terminal voltmeter. With a total dynamic range of 150 dB and narrow band sensitivity at a maximum 0.06 ľV, this makes an excellent receiver for any application. Covers the frequency range of 14kHz to 1GHz in 15 bands and contains a built-in impulse generator for in-the-field accurate calibration and measurement. Meter functions are carrier, quasi-peak, peak and slide back. Outputs are post-IF, pre-IF, video, audio, recorder and X-Y plotting. Can operate from 120 VAC, internal battery supply or from an external DC supply.
