Waveform Discrete Readings - Keithley 4200A-SCS User Manual

Section 4: Pulse card concepts Model 4200A-SCS Pulse Card (PGU and PMU) User's Manual
A waveform measurement can include pre-data and post-data. Pre-data is extra data taken before
the rise time of the pulse; post-data is extra data taken after the fall time (see figure below). See
Waveform measurement timing (on page 4-28) for details on measurement timing for pre-data and
post-data.

Waveform discrete readings

Enabled voltage and/or current readings and time stamps for every sample of the waveform are
returned in a single data set. The following figure shows how waveform discrete readings are returned
as a data set for two pulse periods with voltage, current, and timestamp readings enabled.
