Agile Modulator with IF Loop

Description

Features

Part Number : NTX-8700

The Agile Modulator (NTX-8700) is equipped with the latest CATV electronic technology, including crystals simultaneous PLL vibration circuit, triple SAW synthesized IF circuit, trace filter, CPU control.

NTX-8700 is high quality, vestigial sideband equipment synthesized with audio and video carriers.

NTX-8700 uses audio and video baseband signals coming from video recorder, video camera, or similar equipment as signal source.

Its receiving video input level is 0.5Vp-p~1.5Vp-p.

Working parameters and status are displayed by LCD on front panel, such as output channel, output frequency, A/V ratio, video modulation depth, audio deviation, audio carrier, output level, test signal.

The parameters are selectable by pressing the buttons on the panel.

With complete CPU control, it has self-check monitoring function. Agile output frequency (47~866.250MHz), stepping by 0.25MHz. All the parameters are adjustable through man-machine conversation. IF loop interface. Unique 5-grades trace band pass filter. Audio General
