The SAE Mark VIB is
the ulmost in versatility, reliability and the faithful reproduction of FM
signals. Many new developments are unique to the Mark VIB. Foolproof tuning
accuracy is achieved through the use of these exclusive SEA features. Digital
Readout Frequency Display, the display of tuning and audio signals on a 3"
rectangular oscilloscope, and the automatic selection of this oscilloscope
display by a touch
sensitive tuning
knob.
The Mark VIB is the
industry's first FM tuner which features a direct numerical readout of the
assigned frequency in MHz of the FM station tuned, SAE's Digital readout
measures directly the tuner's own oscillator frequency with an accuracy equal
to that required by the FCC for FM broadcast stations. In addition, the Mark
VIB incorporates ultra-low distortion, outstanding separation and exceptional
quieting and selectivity. It exhibits its superiority in weak signal areas of
congested urban locations where critical tuning is necessary.
Digital readout
Frequency Display
Four long-life Nixie
readout tubes identify the precise station frequency for any of the 100
channels available across the FM band. The readout count is updated 60 times
per second to permit fast tuning across the band. Anti-hunt circuity is
incorporated to prevent inter digital flickering.
Oscilloscope
A high-intensity
3" rectangular oscilloscope accurately displays the presence of multi-path
distortion, center-of-channel tuning, relative signal strength and Lissajous
displays of all stereo and mono signals with provisions for external inputs.
Should a signal be absent, the oscilloscope trace intensity is automatically
diminished.
