AQM (Agile QAM Modulator) accepts one MPEG-2 digital transport stream encapsulated in an ASI (Asynchronous
Serial Interface) format, and delivers one output in QAM format in the 5.75-864 MHz range.

Features

• Input standard supported is ASI with data stream not to exceed 270 Mbps

• Output standards supported are ITU-T J.83 Annex A and Annex B (QAM 16, 32,64, 128, 256, 512, and 1024)

• Optional IF output (Intermediate Frequency) and LVDS input (Low-Voltage Differential Signal) is available

• Compact design allows for deployment of six modules in 2RU rack space
