General.
This Audio/Video modulator is the basic element for the realization
of Compact TV Transmitters, where the CVM/IF is plug-in together
with IF-channel converter on a 3U (132 mm) height single rack unit.
The Audio/Video are the same of classic VAM01/DV modulator.
° Digital-quality.
The CVM/IF uses a back-porch clamping circuit, combined with a full
band linearity corrector it's possible to obtain a perfect video
quality with negligible distortions and intermodulations. All this
means a superior video quality with only a slight difference
compared with digital TV.
°
Compatible with all
standard composite video and
audio signals (PAL, NTSC, SECAM).Available for B,G,M,N,I,D,K,K1 and
L systems. CVM/IF professional multistandard modulator is designed
to produce sound and vision modulated signals at any standard
intermediate frequency.
°
Vestigial sideband SAW
filter. For a perfect vestigial
sideband modulation an high quality SAW filter is used complying all
international standards. This filters outstand for their excellent
linear phase and flat pass-band and group-delay characteristics.
°
Group delay precorrection.
TV receiver group delay precorrection is provided for all standards.
°
White clipper.
The white clipper is factory set to guarantee the best modulation
quality.
°
PLL sound carrier.
Sound and video intercarrier is synchronized by PLL to video line
frequency for maximum stability and negligible intermodulations.
°
Stereo and dual sound.
Available with dual sound facility (optional) for stereo
transmissions.
