4-channel DVB-C Modulator CRT1041M-C

CRT1041M-C is a compact 4-channel DVB-C modulator. The transport stream from four independent multiplexers is received at the DVB-ASI inputs of each of the four modulators. A QAM modulated signal is output to two RF outputs in pairs. The central frequency of the first of the modulators in a pair is tuned in the range of 48-850 MHz, the second is shifted upward by 8 MHz.

The device supports QAM16, 32, 64, 128 and 256 and a fixed symbol rate of 7,000 Msps. The device is intended for use in cable, MMDS and SMATV digital television networks.

Features

• 4 DVB-ASI inputs. EN 50083-9 compatible inputs for receiving data in the form of a DVB transport stream.
• 4 QAM modulators. Four multiplexed streams are modulated independently using one of the modulation types in accordance with EN 300429.
• RF outputs. DVB-C modulated signals are shifted in pairs to the frequency band required by the broadcaster in the range of 48-850 MHz.
• Control. To set and control the parameters of modulators, the device is equipped with a push-button keyboard and a symbolic liquid crystal display.
• AC 220V power supply. 220V power supply is used to ensure the normal operation of the device.
• Compact dimensions. Due to its compact size (19 ”1U), the device can be easily integrated into digital TV broadcast headends.
• Application. CATV, MMDS, SMATV.
