摘要： 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.

摘要： A test and measurement instrument has a user interface, one or more probes to allow the instrument 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 one or more user inputs through the user interface, at least one of the user inputs to identify at least one analysis to be performed on the DUT, receive waveform data from the DUT when the DUT is activated by application of power from a power supply, and application of one of a first and second pulse or multiple pulses from a source instrument, perform the at least one analysis on the waveform data, and display the waveform data and analysis on the user interface. A method of automatically performing a double pulse test and analysis on a device under test (DUT) includes receiving a user input through a user interface on a test and measurement instrument, the user input to identify at least one analysis to be performed on waveform data received from the DUT, receiving the waveform data from the DUT when the DUT is activated by application of power from a power supply, and application of one of a first and a second pulse or multiple pulses from a source instrument, performing the analysis on the waveform data, and displaying the waveform data and analysis on the user interface.
