Product Description

Description

WDQ-3244 4 in 1 QAM is a new compact (1RU only) chassis and cost-effective QAM modulator, which is designed by Hangzhou Prevail according to the DVB related standards. This device is integrated up to 4 channel QAM modulating carrier outputs, in which each carrier has independent signal channel encoding and direct RF output. Hence, one PCS 4 in 1 QAM modulator can work as 4 standalone QAM modulators, significantly reducing the network operators' head-end cost. WDQ-3244 has 4 ASI input, RF output and RF testing output. The WDQ-3244 has very convenient and friendly management interface, the user can complete all operation via local keyboard and LCD display on device, or access through the Ethernet port on device.
