Transmisor de Televisión Línea Profesional.
The PCAV/ series (transmitter) are synthesized and compact equipment
designed to operate in the bands UHF and VHF with TV signal and rated output power of 2, 5
or 10 W.
The apparatus is completely produced with Solid state technology with broadband circuit.
It contains the video group delay precorrector, the linearity precorrector and the Output
Notch filter.
The cabinet allows 19"-3U rackmounting. The modular design ensures great flexibility
and easy access for the maintenance.
- Line offset possibility (option 02)
- External frequency reference
- Synch regenerator (option 04)
- White limiter (option 04)
- Video synch measurement
- Automatic power depletion -3dB when video synch is
not present
- External adjustment frequency reference
- External adjustment sound carrier amplitude
The apparatus can be powered by usual electrical network or external battery of 36VDC.
It can be provided with any of the following:
- input/output channel in the bands I/III/IV/V.
- PAL or NTSC
standard.
