Subsystem Commands
[:SOURce]:<CURRent|VOLTage>:STEP
Query response data <newline>
data returns the present setting. If a parameter is specified, data returns the value
assigned to DEF, MIN, or MAX. Response data type is NR3.
Example :VOLT:STOP 10
:SOUR2:CURR:STAR?
[:SOURce]:<CURRent|VOLTage>:STEP
Sets the sweep step value of the current or voltage sweep output.
Syntax [:SOURce[c]]:<CURRent|VOLTage>:STEP step
[:SOURce[c]]:<CURRent|VOLTage>:STEP? [step]
For <CURRent|VOLTage>, specify CURRent for current output, or VOLTage for
voltage output.
Parameter step Sweep step value. value (see “Source Output Ranges” on page
2-24) |MINimum|MAXimum|DEFault (default is 0). Parameter
data type is NRf+. Query does not support step=value.
The step value can be expressed by the following formula, using the points value set
by the
[:SOURce]:<CURRent|VOLTage>:POINts command and the span value set
by the [:SOURce]:<CURRent|VOLTage>:<CENTer|SPAN> command.
step = span/(points - 1) (where points is not 1)
points=1 sets step=0.
If points is changed, span works as a constant and step is changed. If step is
changed, span works as a constant and points is changed. If span is changed, points
works as a constant and step is changed.
The calculated points value is rounded down to an integer.
The sweep measurement is performed from the start value to the stop value given by
the following formula, even if the specified stop value does not satisfy it.
stop = start + step  (points -1)
For the logarithmic sweep, the step value is ignored and is not used for the
calculation of sweep points.
Polarity of step and span must be the same. Different polarity causes an error.
