The integration time should only cover the portion of the pulse to be measured.
Factor in trigger delays (both internal and user) when determining integration times. Before
the integration process begins (after pulse detection) the internal trigger delay of 10 µs (for
code execution), in addition to any user-specified trigger delay, must elapse.
AUTO time will account for the internal trigger delay (10 μsec) but not for any
user trigger delay (user trigger delay is set using the DELay command).
SENS:PCUR:SYNC:STAT
Pulse current digitization is also known as pulse current burst mode.
•
ON or 1 - Enables trigger synchronization for pulse current measurements. A pulse current
reading will not trigger until the specified trigger level is detected and the specified trigger
delay (both the internal plus the user delay) period expires.
•
OFF or 0 - Disables trigger synchronization and selects pulse current digitization. See
current digitization
for details on digitizing a current pulse or waveform.

:SYNChronize
The smallest step size for trigger delay is 10 µsec. If you specify a smaller step size, it is
adjusted up to the next 10 µsec step value (e.g., 43 µsec is adjusted up to 50 µsec).
After pulse detection but before the integration process begins, the internal trigger delay of
10 μsec (for code execution) in addition to any user specified trigger delay must elapse.
This command is used to set the user trigger delay.
Make sure this setting works with the
Although AUTO accounts for internal trigger delay, HIGH, LOW, and AVERage do not. Note
