Pulsed power may disrupt the operation of standard I-V probes.
Current, voltage and power are now a function of time.
Synchronization of the I-V measurements to the pulse period will be required.
Time resolution much better than the pulse period.
Accounting for the inherent “time delay” between the I-V probes is necessary for power calculations.
Wattmeters can still provide a reasonably accurate average forward and reverse power. (Provided the pulse period is << the response time of the meter.)
