Comments

A complete measurement system for accurately characterizing signals in the 150kHz to 1300MHz frequency range. Operating level from 12mV RMS to 7V RMS (1W peak); 50 Ohm nominal impedance. Measures: carrier frequencies; RF peak power; and modulation, and can recover the modulating signal; also: measure a signal’s frequency, frequency drift, peak power level, AM, FM, phase modulation, and AM and FM noise components. Extremely precise modulation (depth & deviation) measurements. Fully automatic, all major measurements can be made by pushing a single key. Large digital display shows measurement results with excellent resolution. All operations can also be controlled and/or transferred via HPIB. Option 003: External local oscillator connections. Option 004: input power can be from 48 to 440Hz. Includes power cord.

Comments

Low noise, 1000 Hz tuned amplifier and voltmeter with dual scales readable in dB and SWR. Works with square law detectors. Can be used as a tuned amplifier for driving X-Y recorders with 1VDC rear output. Internal precision 60dB attenuator allows it to operate over a 70dB range in 2 or 10dB steps. Sensitivity is 0.15uV RMS for full scale deflection at maximum bandwidth (1 uV RMS on high impedance crystal input). Bandwidth continuously adjustable from 15Hz for maximum sensitivity to 130Hz. With bail stand.
