6 Advanced Source, Measurement, and Control
the number of parameters that are being measured, the model that is doing the measuring, and the
time interval resolution.
5.12 microseconds: 1 parameter (models N678xA SMU only
10.24 microseconds: 1 or 2 parameters (all models)
20.48 microseconds: 3 or 4 parameters (all models, with 20 µs resolution
20.48 microseconds: Up to 8 parameters (all models, with 40 µs resolution
Time interval values from 10.24 up to 20.48 microseconds are rounded to the nearest 10.24-
microsecond increment. Values above 20.48 microseconds are rounded to the nearest 20.48-
microsecond increment when the resolution is set to RES20. Values above 20.48 microseconds are
rounded to the nearest 40.96-microsecond increment when the resolution is set to RES40.
You can change the time interval resolution as follows:
SENS:SWE:TINT:RES RES20
SENS:SWE:TINT:RES RES40
Capture Pre-Trigger Data (optional)
The measurement system lets you capture data before, after, or at the trigger signal. As shown in the
following figure, you can move the block of data being read into the acquisition buffer with reference to
the trigger. This allows pre- or post-trigger data sampling.
The following command offsets the beginning of the acquisition buffer relative to the trigger by 100
points on channel 1:
SENS:SWE:OFFS:POIN 100,(@1)
When the value is 0, all measurement samples are taken after the trigger. Positive values represent
the delay after the trigger occurs but before the samples are acquired. This can be used to exclude
measurement samples that occur during the delay time. (Delay time = offset x sample period).
