2 Press [Next]. The Calibration parameters screen for the Monitor
Diode appears, as displayed in Figure 106. This screen shows
current value for the following quantities:
– [Para], the parasitic power value measured by the Return Loss
module's monitor diode in dBm. This value is determined by the
termination calibration, or you can use the default setting held in
the factory calibration.
– [Ref], the power measured by the Return Loss module's monitor
diode during the reflectance calibration in dBm
