Abstract:
A test and measurement instrument has a user interface, one or more probes to connect to a device under test (DUT), and one or more processors configured to execute code to cause the one or more processors to: receive waveform data from the DUT after activation of the DUT by application of power from a power supply, and application of at least a first and second pulse from a source instrument, locate one or more reverse recovery regions in the waveform data, determine a reverse recovery time for the DUT from the reverse recovery region, and display a reverse recovery plot of the one or more reverse recovery regions on the user interface, the reverse recovery plot being automatically configured to display one or more of the reverse recovery regions, and including at least one characteristic for the one or more reverser recovery regions annotated on the reverse recovery plot. A method of providing reverse recovery measurements for a device under test (DUT) includes receiving waveform data through the probes from the DUT after activation of the DUT by application of power from a power supply, and application of a first and second pulse from a source instrument, locating one or more reverse recovery regions in the waveform data, determining a reverse recovery time for the DUT for the one or more reverse recovery regions, and displaying a reverse recovery plot of the one or more reverse recovery regions on the user interface, the reverse recovery plot being automatically configured to display the one or more reverse recovery regions, and including at least one characteristic of the one or more reverse recovery regions annotated on the reverse recovery plot.
