Function Details
I/V-t Sampling Measurement
I/V-t Sampling Measurement
For the I/V-t sampling measurements, source channels (SMU) force constant current
or voltage, and monitor channels (SMU) measure current or voltage changes at a
device under test (DUT) with a specified sampling interval.
Available Measurement Resources
SMUs and SPGUs can be used. SMU can be constant voltage source or constant
current source and perform voltage measurement or current measurement. SPGU
can be pulse voltage source. See
“SPGU Module” on page 4-27 for using the SPGU.
NOTE To use the SPGU, the sampling interval must be 2 ms.
Operation Summary
I/V-t sampling measurement is executed as explained below. See Figure 4-9. In this
example, the Output Sequence is set to SEQUENTIAL. And the bias hold function
sets the bias to the Base value.
Figure 4-9 Operation Summary
In this figure, a and b in the formula of Time indicate the time from the start of one
point measurement to the start of integration by the A/D converter.
