Switching Analysis Measurements panel (optional).
Measurement Description
Switching Loss The mean instantaneous power and energy in the turn-on, turn-off, and conduction
regions of a switching device. Provides the SWL trajectory plot.
dv/dt The rate of change (slew rate) of the voltage, as it rises from the Base reference
level (R
B
) to the Top reference level (R
T
), and as it falls from the Top reference level
(R
T
) to the Base reference level (R
B
).
di/dt
The rate of change (slew rate) of the current, as it rises from the Base reference level
(R
B
) to the Top reference level (R
T
), and as it falls from the Top reference level (R
T
)
to the Base reference level (R
B
).
SOA An X-Y plot of switching device voltage and current. The SOA mask testing provides
pass/fail testing to component specifications.
R
DS(on)
The resistance (the slope of the V-I curve) when the switching device is conducting.
Magnetic Analysis Measurements panel (optional).
Measurement Description
Inductance
The integral of the voltage divided by the current of a magnetic component during
circuit operation.
Magnetic Property The BH curve for a magnetic component during circuit operation.
Magnetic Loss The average value of the product of the voltage and current through the inductor.
This represents the total loss of the magnetic device and consists of resistive and
eddy current losses during circuit operation.
I vs. ∫V The integral of voltage against current.
Output Analysis Measurements panel (optional).
Measurement Description
Line Ripple The RMS and peak-to-peak values of the line frequency portion of the AC signal.
Switching Ripple The RMS and peak-to-peak values of the input signal.
Efficiency The ratio of output power to input power for a power conversion circuit.
Turn On Time Measures the time from when the input voltage is applied to the DUT to the time
when the output voltage reaches a steady level.
Turn Off Time
Measures the time from when the input voltage is removed from the DUT to the time
when the output voltage reaches a zero level.
NOTE. You should take the Turn On Time and Turn Off Time measurements on their own (ignoring the results of other
measurements in the
Results bar).Turn On Time and Turn Off Time measurements use the Power seq setup function to
optimize the settings and trigger to measure the DUT power-on signal, which may result in inaccurate measurements for other
measurement types.
NOTE. if you save a session file that includes power measurements, make sure to recall (load) the session file into an instrument
with the same number of channels that was used to create the session file.
