  • LDM***0 is a frequency agile professional grade, microprocessor controlled CATV mini demodulator. The unit accepts any NTSC television signal in the *****6MHz frequency-range converting it to baseband video and audio, while maintaining over *0Db S/N ratio. Its design enables it to be installed in other manufacturers mini-mod chassis. The units phase locked- loop frequency control, envelope signal detection, and superior SAW filtering minimize adjacent channel interference and assure accurate and spurious free performance. IRC or HRC offsets can be activated via push- switches on the front panel. The units PLL circuitry in conjunction with the non-volatile memory contained in the microprocessor ensures easy and reliable channel selection and restoration.

  • LCM**5 a high-performance CATV/CCTV Audio Video Mini-Modulator. This modulator accepts any audio-video baseband television signal and provides a *5dBmV minimum output and a *6dB in-band carrier to noise ratio providing superior picture quality. LCM**5 covers channels 2 to **5 with frequency range from *4 to **6 MHz while accommodating HRC and IRC offset frequencies. It is SAW filtered for superior adjacent channel performance enables drop-in channel expansion. The Single-slot design allows up to *2 or *6 units in universal standard chassis. It is also compatible with most manufacturers mini modulator chassis. The front panel access controls design enables easy setup. It is also available for optional PAL format channels.
