NOTES:
(1) Optional express port will increase input power range by 1 dB. Optional DMux will increase input power range by 1.5 dB.
(2) Typical RF output per 6 MHz QAM. Total load of 6 such SC-QAM for 5-42 MHz load and 33 for 5-204 MHz load. Note 3 applies to all standard receivers and note 4 applies to all high sensitivity receivers. Subtract 68 dB from these powers to convert to dBmV/Hz.
(3) Standard receiver at -12 dBm optical input, 10% OMI on transmitter, 0 dB internal attenuation, 0 dB output plug-in pad. Level will be reduced 2 dB if express ports are present and 3 dB if DMux is present.
(4) High sensitivity receiver at -20 dBm optical input, 30% OMI on transmitter, 0 dB internal attenuation, 0 dB output plug-in pad. Level will be reduced by 2 dB if express ports are present and 3 dB if DMux is present.
(5) Automatic RF attenuation change based on received optical levels (2:1 RF:Opt).
(6) Measured with same optical input level on all four receivers. Measured as delta between intended output channel and an interfering
channel from adjacent receiver.
