SMU Pulse Output
When SMU is pulsed source, set pulse parameters in following ranges:
Pulse width 0.5 ms to 100 ms, 100 μs resolution
Pulse Period 5 ms to 1 s, 100 μs resolution
where pulse period ≥ pulse width + 4 ms
Be aware that if any of following are true, pulsed SMU channel may not output the
pulse period and pulse width you specified:
• Measurement range differs from compliance range (lowest range that includes
compliance).
• Ranging mode is set to auto range or limited auto range.
• Multi-channel measurement is set.
Compliance Range for Pulsed SMU
If you use an SMU as a pulsed source, the compliance setting range is as follows:
• Current Compliance
For SMU used as pulsed voltage source, you can set current compliance as
follows:
