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.
This command sets the voltage slew rate in volts per second. The slew
rate setting affects all programmed voltage changes, including those
due to the output state turning on or off. The slew rate can be set to
any value between 0 and 9.9E37. For very large values, the slew rate
will be limited by the analog performance of the output circuit. The
keywords MAXimum or INFinity set the slew rate to maximum.
Internally, the slew rate is controlled by a 24-bit register. The slowest
or minimum slew rate is a function of the full-scale voltage range. For
a model with a 50 V range, the minimum slew rate is about 4.76 V/s.
For other voltage ranges the minimum slew rate is proportional to
this value, so for a model with a 5 V range the minimum slew rate is
about 0.476 V/s. The unit accepts slew rates as low as 0 V/s, but
values sent to the 24-bit register will be limited at 1 count.
The query returns the value that was sent, unless the value was less
than the minimum slew rate, in which case the minimum value is
returned. The LSB weight of the 24-bit register can be queried using
VOLT:SLEW? MIN. The exact value varies slightly according to the
voltage calibration.
The *RST value = 9.9E37.
