Note Effecting a range change takes considerable time (6 secs) as the amplifiers
have to be powered down to be reconfigured and your application program
should allow for this execution time of the VOLT:RANGE command.
Note that the query format of the VOLT:RANG command returns the voltage range value for
the selected range and mode. In AC or AC+DC mode, an AC voltage range value is
returned. In DC mode, the DC voltage range value is returned. To determine the state of the
MX unit, it may be necessary to query both the range and the mode.
Note: On MX units with firmware revision 4.24 or higher, the VOLT:RANG command
is also coupled with the OUTPUT command. If the output relay is closed (ON),
attempting a voltage range change will result in an error message and no
range change will occur. The output relay MUST be opened first by sending a
OUTPUT 0 command. The output off command can be prepended to the
volt:range command as part of the same message.
The VOLTage:RANGe command is coupled with the CURRent command.This means that
the maximum current limit that can be programmed at a given time depends on the voltage
range setting in which the unit is presently operating.

This command selects the source from which the output voltage is sensed. The following
voltage sense sources can be selected:
INTernal This senses the voltage at the output of the power amplifier on the in-board
side of the output disconnect relay.
EXTernal This senses the output voltage at the user's sense terminals, which allows
remote voltage sensing at the load.

This command sets the slew rate for all programmed changes in the output voltage level of
the source. A parameter of MAXimum will set the slew to its maximum possible rate. The
SCPI representation for MAXimum is 1E9.
