IEEE-488 Reference
3-107
Note that the amplitude level is limited by the selected range and programmed voltage limit (see
:RANGe and :LIMit). When on the 100V range, attempts to set the amplitude to a level that ex-
ceeds the 100V range will result in a Setting Conflicts error. Attempts to set an amplitude that
exceeds a programmed voltage limit will set the amplitude to that limit.
The MINimum and MAXimum parameters are also affected by range and voltage limit. Setting
the V-Source to the MINimum (or MAXimum) amplitude selects the greatest negative (or pos-
itive) value allowed by the programmed limit or range.
The V-Source output (operate and standby) is controlled from the :OUTPut1 subsystem (see
paragraph 3.17).

Description This command is used to select the optimum range for the V-Source. Specifying the output volt-
age value automatically selects the most sensitive range. For example, specifying a value ≤100
selects the 100V range. Specifying a value >100 selects the 1000V range.
You cannot select the 100V range if the programmed amplitude value is greater than 100. A set-
ting conflict error will result.

Query :LIMit? Query voltage limit
:LIMit? DEFault Query *RST default limit
:LIMit? MINimum Query minimum limit
:LIMit? MAXimum Query maximum limit
Description This command is used to set an absolute value limit for the V-Source. For example, setting a
limit of 75V limits the V-Source output to ±75V.
The specified voltage limit is only in effect if the limit is enabled (see :LIMit:STATe). If dis-
abled, the limit is simply dictated by the selected range.
