The 3000B Communications Service Monitor is a compact, lightweight (25lbs) service monitor or testing FM and AM transceivers. Frequency range is 400KHz to 1000MHz in 100Hz steps. Has an audio synthesizer which permits generation of sub-audible tones and timed tone bursts. In receive mode, an internal counter displays frequency error, modulation frequency or received sub-audible tone frequency. RF voltage level is continuously variable from 0.03 ?V RMS to 316 mVRMS. An internal CRT display shows modulation waveform and relative signal strength. An analog meter reads modulation and SINAD. Has an internal load to protect it from accidental keying.
