Setup and Programming, (cont) / Operation QAM MODE: This menu allows the user to set the modulation type for the output. Choices range from QAM-16A through QAM-1024B. 'A' suffixes indicate DVB compliant FEC and the B suffixes indicate DigiCipher II FEC encoding. Note that the output QAM mode usually must be QAM-256. For CATV systems using DigiCipher II, select the QAM-256B mode. For DISH Network QAM distribution or other DVB systems using DVB set tops, choose the QAM-256A mode.
Additional Information ADDITIONAL INFORMATION SET TOP BOX MAPPING The output stream of the MQM6000L will contain programs xx - 1 thru 6 where xx is the RF output channel and 1 thru 6 are the MPEG program numbers assigned that correspond to the ASI inputs1 thru 6. STANDBY MODE The MQM6000L has a standby output mode which turns off the RF output. This can be used when it is desirable to temporarily disable the output without unplugging the AC line cord. Select STANDBY in the OUTPUT FORMAT menu.
