Neurotronix - Agile Modulator without IF Loop

Agile Modulator without IF Loop

Description

Features

Part Number : NTX-AG5500

NTX-AG5500 is equipped with the latest CATV electronic technology, including crystals simultaneous PLL vibration circuit, SAW filter, trace filter, CPU control. NTX-AG5500 is high quality, vestigial sideband equipment synthesized with audio and video carriers. NTX-5500 uses audio and video base band signals coming from satellite receiver . Its receiving video input level is 0.5Vp-p~1.5Vp-p. The channel number is displayed by Seven Segment on front panel.

Double digital PLL, CPU control. Output RF modulation frequency is adjustable in the range of 48~550MHz. Preset standard channels enable to select any channel at discretion. Audio carrier 4.5/5.5/6.0/6.5MHz is selectable on panel. Every channel carrier can be trimmed by 0.25MHz. Automatic storage, memory after power off.
