FM-AM Signal Generators include Type 202H for testing and calibrating FM receiving systems in broadcast FM, VHF-TV, and mobile communications, and Type 2025, specifically designed for coverage of the vhf telemetering band. 207H Accessory Univerter, pro- vides IF coverage when used with either the 202H or 2025. Others are the Type 2254, a high-stability, general purpose model and the Type 240A, a sweep sig- nal generator for visual alignment of broad-band circuits and its accessory Univerter. Type 203B, extending the lower limit of basic frequency coverage. 219A FM Stereo Modulator provides a multi- plex output signal for the recently ap- proved FM stereo broadcast system in accordance with FCC Docket 13506. The output of the 219A may be used directly for the test and alignment of base-band circuits or may be used to modulate the 202H Signal Generator providing a complete stereo signal at rf. 230A Signal Generator Power Amplifier, when driven with a conventional signal gen- erator, provides high level rf power for use in receiver testing, voltmeter and wattmeter calibration, attenuation measurements, and antenna, filter, and component testing. Because of its excel- lent noise figure, the 230A is also well suited to low-level applications includ- ing receiver pre-selection, tuned selec- tive filtering, harmonic amplification, and pre-amplification for electronic fre- quency counters. 245C,D Signal Generator Calibrators provide a rapid and convenient means for check- ing and calibrating the rf output and amplitude modulation of signal gen- erators. They also provide calibrated rf levels in the microvolt range for the precision measurement of receiver sensitivity. 8900A Peak Power Calibrator provides a con- venient means of directly reading the peak RF power of pulses. The power level, indicated directly on the panel meter, is completely independent of duty cycle. The instrument consists of a precision terminated input circuit, di- ode detector, dc reference supply,and a chopped video output system. May be readily standardized against external bolometer or calorimeter. Aircraft VOR/ILS/DME/ATC Beacon Test Equip- ment includes specialized signal gen- erators for the testing and calibration of aircraft systems. Crystal Monitored Signal Generator, Type 211A provides coverage for VOR and ILS localizer, as well as VHF communications; Glide Slope Signal Generator, Type 2324, provides coverage for ILS glide slope; Navigation Aids Test Set, Type 235A provides complete facilities for DME and the ATC Beacon.
