l
This command is coupled with the [SOURce:]CURRent command. This means that if a range com-
mand is sent that places an output on a range with a lower maximum current than the present cur-
rent level, an error is generated. This also occurs if a current 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
l
If programming a range value causes a range change to occur while the output is enabled, the out-
put 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 .
[SOURce:]CURRent:SLEW[:IMMediate] < value >, (@<chanlist>)
[SOURce:]CURRent:SLEW[:IMMediate]? [MIN|MAX,] (@<chanlist>)
Sets the current slew rate. The slew rate is set in amps per second and affects all programmed
current changes, including those due to the output state turning on or off. The slew rate can be set to
any value between 0 and 9.9E+37. For very large values, the slew rate will be limited by the analog
performance of the output circuit. The keywords MAX or INFinity set the slew rate to maximum.
Parameter Typical Return
0 – 9.9E+37|MIN|MAX|INFinity, *RST MAX <slew rate>
Sets the output slew rate to 1 A per second: CURR:SLEW 1, (@1)
l
The query returns the value that was sent. If the value is less than the minimum slew rate, only
the minimum value is returned. The resolution of the slew setting is also the minimum value, which
can be queried using CURRent:SLEW? MIN. The exact value varies slightly according to cal-
ibration.
[SOURce:]CURRent:SLEW:MAXimum 0|OFF|1|ON, (@<chanlist>)
[SOURce:]CURRent:SLEW:MAXimum? (@<chanlist>)
Enables/disables the maximum slew rate override. When enabled, the slew rate is set to its maximum
value. When disabled, the slew rate is set to the immediate value set by the
[SOURce:]CURRent:SLEW command. Use [SOURce:]CURRent:SLEW? MAX to query the maximum
slew rate.
Parameter Typical Return
0|OFF|1|ON, *RST OFF 0 or 1
Disable the maximum slew rate: CURR:SLEW:MAX OFF, (@1)
l
The [SOURce:]CURRent:SLEW:MAX command is coupled to the [SOURce:]CURRent:SLEW com-
mand. If [SOURce:]CURRent:SLEW sets the rate to MAX or INFinity,
[SOURce:]CURRent:SLEW:MAX is enabled. If the slew rate is set to any other value,
[SOURce:]CURRent:SLEW:MAX is disabled.
