DPC Scaling Function
Figure C-1 DPC Scaling Function
Figure C-1 illustrates the scaling function, based on the ratio of power level to
data rate, of the DPC system. Once this ratio is mapped out for the system, the
DPC scaling function will automatically determine the appropriate power level
for any given data rate. Three parameters are essential for this scaling function:
•Calibrated Data Rate
•Calibrated Nominal Power Level
•Maximum Power Level
As determined during initial system turn-up, the Calibrated Data Rate and the
Calibrated Nominal Power Level values for the CDM are entered into the VMS
Home State menu. The Maximum Power Level (the point at which the signal
reaches saturation) for the Calibrated Data Rate is then determined, and entered
into the VMS DPC menu (or the CLI Dynamic Power Control Configuration
menu). If these home state parameters have not been entered, DPC will not be
