This command sets the over-voltage protection (OVP) level of the
output channel. The values are programmed in volts. If the output
voltage exceeds the OVP level, the output is disabled and the
Questionable Condition status register OV bit is set.
An over-voltage condition can be cleared with the Output Protection
Clear command after the condition that caused the OVP trip is
removed. The OVP function can be disabled using
VOLTage:PROTection:STATe.
The *RST value = MAX.
This command only applies to models that have programmable
ranges. Refer to Appendix A for the available ranges for each model.
This command sets the output voltage range. Units are in volts. The
instrument selects the range with the best resolution for the value
that is entered. When queried, the returned value is the maximum
voltage that can be output on the range that is presently set.
This command is coupled with the [SOURce:]VOLTage command.
This means that if a range command is sent that places an output on
range with a lower maximum voltage than the present voltage level,
an error is generated. This also occurs if a voltage level is
programmed with a value too large for the present range.
These types of errors can be avoided by sending the both level and
range commands in the same SCPI message. When the range and
setting information is received as a set, no range/setting conflict
occurs.
The *RST value = the highest available range.
If programming a range value causes a range change to occur while the output
is enabled, the output will be temporarily disabled while the range switch
occurs. The transition from on-to-off and then from off-to-on will also be
delayed by the settings of OUTPut:DELay:FALL and OUTPut:DELay:RISE.
