Ripple
The Ripple measurement result is displayed in either Watts or Volts. The amplitude units selected on
the Setup > Analysis > Units tab determine whether the measurement is presented in Watts or Volts.
Volts are shown for linear units (for example, volts or amps); Watts are shown for non-linear units (for
example, watts or dBm).
The Ripple measurement, in Watts, is calculated as follows:
Where:
DelPos = Delta Positive in Volts
RefPos = Reference Positive in Volts
DelNeg = Delta Negative in Volts (this is a positive value)
RefNeg = Reference Negative in Volts
The Ripple measurement, in Volts, is calculated as follows:
Where:
RatioPosV = DelPos/RefPos
RatioNegV = DelNeg/RefNeg
