VSB FIXED MODULATOR MERK PRO-X

KMD 2101

 

Merk : PRO X
Kode Produk : KMD 2101

Pro-X KMD2101 is an adjacent modulator with fixed-frequency output and high performance. Since constant frequency technology of crystal oscillator featured high accuracy and high stability is adopted for the product, it provides stable output frequency with no phase jitter and phase noise. Professional integrated circuit and high-quality SAWF (surface acoustic wave filter) are used for video/audio units: it ensures excellent vestigialo side band response and high out-of-band suppression. High output ability and extremely low distortion are also its advantages. Furthermore, the use of annular transformer makes small EMI (electromagnetic interference). After all, the devices has high performance to cost ratio, and is one of the best choices for CATV stations.

GM - 3000

 

Merk : PRO X
Kode Produk : GM - 3000

The GM-3000 is a professional quality agile modulator, wich can be used as an alternate IF input and specifically designed for use of Head-end system of CATV. this product provides audio and video modulated RF carrier on any channel in the 47 to 870MHz frequency range. many standard audio/video source can be used, such as satellite receivers and video tpe cecorders. This modulator has a wide range of standard and optional feature that make it very suitable for advanced MATV, SMATV or CATV system.

VSB AGILE MODULATOR MERK PACIFIC

PM - 2860

 

Merk :Pacific Satellite
Kode Produk : PM - 2860














This agile TV modulator provide audio and video modulated RF signals on TV channel which is selectable throught frequency range: 45~870MHz. Any standart audio/video source can be used: Satellite receiver, TV Camera, Video tape recorder or TV demodulator.
Three pushbuttons on the front panel operate on a built-in microprocessor which selects the Video Carrier Frequency, the Video/Audio Carrier Level Ratio and Video/Audio Modulation Index. A comprehensive liquid crystal display, whose position on the panel displays the performed selection.The modulation process operates on a local crystal-controlled IF signal, which via SAWF is directed to a double frequency conversion that uses PLL synthesized local oscillators.
SAWF filtering provides true VSB (Vestigial Side Band) response and enables the modulator to be used in adjacent channel systems. An external IF loop permits the internally generated standart IF to be replaced by an alternate composite IF - stereo or dual sound, as well as to apply signal scrambling system.
