Please enter the correct analog, QAM channel numbers and delta level based on
the actual application, otherwise the RF input value of the forward driver
amplifier module will be inaccurate. If the digital signal consists of the signal
from the broadcast RF input port and the narrowcast RF input port, the number
of the QAM channel equals to the number of the input signal channel at the
broadcast RF input port plus the number of the input signal channel at the
narrowcast RF input port.
The default settings of channel load are: 59 for analog channel number; 53 for
QAM channel number; and 6. 0 dB for delta level. The cursor stays in the “Analog
Number” field by default.
