A. Set the voltage reference, i.e. the switch level at the edge
of the input switch. This value is a percentage of the
maximum switching voltage. Adjusting the value to ignore
background noise. This value is used to determine the
threshold hysteresis of the switch edge
B. Set the current reference, i.e. the switch level at the
beginning of the input switch edge. This value is the
percentage of the maximum switching current. This value
can be adjusted to ignore background noise or invalid
offset that is difficult to eliminate in the current probe. This
value is used to determine the threshold hysteresis of the
switch edge
C. Set the conduction type (Waveform, Rds(on) or Vce(sat))
D. Set Rds(on) resistance
E. Set Vce voltage
F. Return to the previous menu
Conduction Type
Waveform -- The power waveform uses the original data, and the calculation formula is P = V * I，E
= P * T.
Rds (on) -- In the on area (where the voltage level is lower than the voltage reference (adjustable)),
the power calculation formula is P = I
2
* Rds (on). In the off area (where the current level is lower than
the current reference (adjustable)), the power calculation formula is P = 0 watt.
Vce (sat) -- In the on area (where the voltage level is lower than the voltage reference (adjustable)),
the power calculation formula is P = Vce (sat) * I. In the off area (where the current level is lower than
the current reference (adjustable)), the power calculation formula is P = 0 watt.
