:STIMe <n>
This command is used to specify the setting time.
Usage
:ROUTe:SCAN:STIMe <n>
:EXTernal?
:EXTernal? DEFault
:EXTernal? MINimum
:EXTernal? MAXimum
<n>
 0.003 to 99999.999: Specify settling time in seconds
 DEFault: 0 seconds
 MINimum: 0 seconds
 MAXimum: 99999.999 seconds
Details
This command is used to specify the settling time for the relay switches on the internal scanner card.
After each switch closes, a measurement does not occur until after the specified settling time expires.

:SMEThod <name>
This command is used to select the switching method.
Usage
:ROUTe:SCAN:SMEThod <name>
:SMEThod?
<name>
 VOLTage: Break-before-make switching method
 CURRent: Normal switching method
Details
This command is used to select the switching method during an internal scan. The VOLTage method
ensures that each switch opens (breaks) before the next switch in the scan closes (makes). This
method ensures that two or more channels cannot be closed at the same time.
Use the CURRent switching method for optimum speed in applications where "break-before-make" is
not necessary.
