|Description||Communications Service Monitor|
The Model 30008 is a compact, lightweight Service Monitor for testing FM and AM transceivers . Its low (25 lb) weight permits use in the field, powered by a vehicle battery. The frequency range is 400 kHz to 1000 MHz in 100 Hz steps. An audio synthesizer permits generation of subaudible 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 pVRMS to 316 mVRMS. An internal CRT display shows modulation waveform and relative signal strength . A meter reads modulation, SINAD (using the internal 1 kHz tone source), audio input voltage, or RF power from 1 to 100 W. The internal load eliminates the possibility of damage from accidental keying . The meter and CRT both display the same information, including SINAD, noise and distortion ; however, only the meter indicates power, and only the CRT indicates relative signal strength .
