•
MIN
selects the minimum range available with the VOLTage:AC:RANGe
command: 0.0875V. MAX selects the maximum range available: 300 V.
• You must select a range using VOLTage:AC:RANGe before specifying resolution.
Also, in order to specify an aperture time of 10 µs, you must select a fixed range.
• Specifying a fixed range disables the autorange mode set by the
VOLT:RANG:AUTO command.
• The VOLT:AC:RANG command overrides the range setting from a previous
CONFigure command specifying the same function. With the new range, a new
resolution is also selected. However, this resolution is based on the aperture time
set by
CONFigure.
• Changing the AC range changes the DC voltage range to a corresponding value
(the AC range is
7
⁄
10
of the DC range).
• *RST Condition: VOLT:AC:RANG 5.6V

VOLTage:AC: RANGe?
[SENSe:]VOLTage:AC:RANGe? [MIN | MAX] returns one of the following
numbers to the output buffer.
The present voltage range selected if
MIN or MAX is not specified. Only the ranges
available with the
RANGe command are returned. For example, if CONFigure selects
the 0.63 V range, 0.7 V is the range returned.
The minimum voltage range available with the
VOLTage:AC:RANGe command
(0.0875 V) if
MIN is specified.
The maximum voltage range available with the
VOLTage:AC:RANGe command
(300 V) if
MAX is specified.
