Informationen:
                                    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 .
