Drake MQM6000L Multiplexing QAM Modulator - Manual (Page 4)

4
Six Inputs: 270 mHz clock rate, 40 mbps maximum tS rate at each input.
Programs: mPtS or SPtS
RS232 CONTROL
Multiplexing and Program Filter: one SPtS may be selected from each input. the selected programs will be multiplexed as long
as the data rate of the resulting mPtS does not exceed the output qAm channel capacity.
Null Packet Processing: fixed output clock mode
