About Source Power Cal

Description

This command, along with MaximumIterationsPerPoint Property deal with ADUSTMENTS made to the source power.

Sets the maximum desired deviation from the sum of the test port power and the offset value.  Power readings will continue to be made, and source power adjusted, until a reading is within this tolerance value or the max number of readings has been met. The last value to be read is the valid reading for that data point.

The following two commands allow for settling of power READINGS.
