VOLTage:MODE
Phase Selectable
This command determines how the output voltage is controlled during a triggered output
transient. The choices are:
FIXed The voltage is unaffected by a triggered output transient.
STEP The voltage is programmed to the value set by VOLTage:TRIGgered when
a triggered transient occurs.
PULSe The voltage is changed to the value set by VOLTage:TRIGgered for a
duration determined by the pulse commands.
LIST The voltage is controlled by the voltage list when a triggered transient
occurs.

This command sets the voltage range of the power source. On the MX/RS Series, up to
three voltage ranges are available:
• 150 V AC or 200 V DC range
• 300 V AC or 400 V DC range
• 400 V AC or other (-XV) range
The LIM:VOLT? Query may be used to determine which AC voltage ranges are available to
select. This command always returns the AC voltage range values. When in DC mode,
used 200 iso 150 or 400 iso 300 to select the low and high DC voltage range. Sending a
parameter other than these will not be accepted.
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.
