Function Details

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.
