IEEE-488 Reference
3-84
Description This command is used to select the switching method during an internal scan. The VOLTage
method ensures that each switch will open (break) before the next switch in the scan closes
(make). 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.

:ROUTe:SCAN:VSLimit <b> Control 200V V-Source Limit
Parameters <b> = 0 or OFF Disable 200V V-Source Limit
1 or ON Enable 200V V-Source Limit
Query :VSLimit? Query state of 200V V-Source limit
Description This 200V V-Source limit is used to help protect internal scanner cards from high voltage that could
damage them. With the 200V limit enabled, the V-Source can never source more than +/-200V.
Note that the :SOURce:VOLTage:LIMit command is also used to set the voltage limit of the V-
Source. Of the two voltage limit methods, the one that is set to the lower limit value (absolute)
is the one that will be in effect.
