Settling Times - Keithley 4200A-SCS User Manual

Section 3: Setting up PMUs and PGUs in Clarius Model 4200A-SCS Pulse Card (PGU and PMU) User's Manual

Settling Times

The settling time is the time that it takes for pulse levels to stabilize after the voltage or current is
changed, such as during execution of a sweep.
The Typical Minimum Timing Recommendations dialog box displays typical minimum timing versus
current measure range recommendations. These are the recommended minimums for each current
measure range. Longer times may be required to accommodate DUT and interconnect settling.
Figure 51: Typical minimum timing recommendations
When using autorange with an RPM connected, use the timing values on the top row (or
longer/slower values). If using limited autorange, start with the timing values for that range.
If pulse width or period timing parameters are too narrow for a chosen measure range, a message is
displayed showing the change to the current measure range for each effected channel. To avoid
these changes, follow the guidelines shown in the previous figure. See PMU minimum settling times
versus current measure range (on page 3-34) for more information.
