CETUSMK II PAL D/K (B/G)
Frequency Agile Television Modulator
Description
The CETUSMK II Frequency Agile Television Modulator is a
high-quality, microprocessor controlled modulator used in large-
sized broadband networks. It is used to convert audio and video
signals into RF output signals. High performance plus agility
makes it suitable for systems requiring backup modulators.
Features
All agile channels from 47 MHz to 870 MHz
Front panel LCD and buttons for user-friendly control
Independent oscillation in IF 38 (38.9) MHz - SAW for IF and high SNR
Low differential gain and differential phase
PLL frequency composite in video carrier frequency and audio carrier frequency
Unique diode dual balance design with good linearity and low noise
Video AGC function with modulation depth of 87.5%
IF video and audio interfaces for scrambling; clamping switch for video scrambling
Automatic RF amplitude stabilizer
Local or remote status monitoring and control via RS-485
Support ROSA/ TNCS element management
19-inch (1 RU) chassis with independent power supply
