I-18 Delta, Pulse Delta, and Differential Conductance
Power calculation
With WATTS (power) measurement units selected, power for Differential Conductance is
calculated using Average Voltage (see
rent. Average Current is calculated by the Model 622x as follows:
AvgCurr
Where: AvgCurr is the Average Current corresponding to a given Differential
With Average Voltage and Average Current known (calculated by the Model 622x), power
is then calculated as follows:
