NOTES:
(1) Ships with MN0PAD. See page 6.
(2) Ships with 0 dB QAE EQ. See page 6.
(3) A maximum of five forward high gain amplifiers can be used in one active chassis, if it is powered with MNAC-110, MNAC-220, or MNDC power supplies.
(4) Tested with 150x QAM 256 channels up to 1002 MHz at specified output power, as well as 4 CWs @ +6 dB output relative to QAMs to simulate pilot channels.
(5) See chart for other maximum output ratings for the number of QAM channels.
(6) If any analog channels present then they should be ≥ 10 dBmV to avoid CNR impacts.
This means min. QAM level would be -6 dB relative. If all QAM channels, then QAMs may be as low as -2 dBmV/ QAM 256.
(7) Pre-FEC BER. Results show no detectable bit errors if operated within recommended range.
