Sampling (Time Domain) Measurement Characteristics
Displays the time sampled voltage/current data versus time. The source unit is
SMU, VSU, or PGU.
Sampling points Maximum 10,001 (Linear)
Sampling mode linear, log, and thinned-out
Sampling interval For linear scale (auto mode):
•60 μs to 480 μs range, 20 μs resolution
• 480 μs to 1 s range, 80 μs resolution
• 1 s to 65.535 s range, 2 ms resolution
For linear scale (no limit mode), log scale, and thinned-out
modes:
• 560 μs (720 μs at thinned-out mode) to 1 s range, 80 μs
resolution
• 1 s to 65.535 s range, 2 ms resolution
Hold time initial wait time, 0.03 to 655.35 s, 100 μs resolution.
Stop condition a condition to stop the sampling can be defined.
Sampling interval setting accuracy (supplemental data)
• 0.5 % + 10 μs (sampling interval
≤ 480 μs)
• 0.5 % + 10 μs (560 μs
≤ sampling interval < 2 ms)
• 0.5 % + 100 μs (2 ms
≤ sampling interval)
The thinned-out mode is similar to reverse-log sampling. Sampling measurement
continues by thinning out older data until the sampling completion condition is
satisfied.
There are the following restrictions if initial interval is less than 2 ms.
• Number of measurement channels must be 1.
• Measurement ranging must be the fixed range.
• Stop condition must be disabled.
