• Combined vision and dual/stereo sound modulator with RF output in the VHF range and the UHF range.
• Dual/stereo sound in conformity with the German system.
• Pre-corrected group delay and rudimentary sideband characteristics.
• Ideal for low - power, dual sound/stereo transmitters in CATV networks as well as central transmitter
in TV factories.
The PM5672 D DS TV modulator is a complete television modulator (transmitter) with inputs for video and two audio channels and output for VHF or UHF radio frequencies.
Extreme accuracy and stability are obtained with new technology, such as synthesised carrier generation and a surface-acoustic wave filter (SAW) for the amplitude response shaping. Although the PM5672 is economically priced it features the following broadcast characteristics only found in more expensive modulators:
• Rudimentary side-band characteristics
• Group delay pre-correction
• Low distortion
• Channel output with very low spurious and harmonic content
• Precision meters, front mounted, for modulation control
• Stereo or two-channel sound
The PM5672 is ideal for television distribution systems such as those used in TV and video cassette recorder factories, closed circuit and cable TV networks. The SAW filter ensures adjacent channel operation without interference. The PM 5672 is ideal as a cost effective exciter in low power TV transmitters.
The PM5672 is supplied fully adjusted to a specific TV channel & vision/sound frequencies as well as TV systems.
When the instrument is delivered it is set-up for the version ordered. Changing the instrument from one version to another requires jumpers position changes and altering a few components change (see: service manual - programming plugs).
