8753ES R-Channel Input
Dynamic Accuracy (Typical)
Accuracy of the R-channel power reading relative to the R-channel reference power level.
This table applies when the calibrated power level and the measurement power level are not the
same.
Inputs:
• R-channel
• For Option 075 and 014, for test port powers up to the maximum source power.
