VTAM-520

Mini Agile Modulator Chassis

The ViewTEQ VTAM-520 is a professional grade microprocessor-controlled agile audio/video mini-modulator. This modulator accepts any audio-video baseband television signal and provides a 45dBmV minimum output on CATV channels 2 to 135 (54-860 MHz). Channel selection is easily accomplished via channel up/down buttons located on the front.  Up to 10 VTAM-520 mini-modulators units can be installed in the VTAMC-520 chassis. The unit’s PLL circuitry, in conjunction with the non-volatile memory contained in the microprocessor, ensures easy and reliable channel selection and restoration. The VTAM-520 modulator is shipped with all internal adjustments preset.
