Subsystem Commands
[:SOURce]:SWEep:POINts
Syntax [:SOURce[c]]:SWEep:DIRection direction
[:SOURce[c]]:SWEep:DIRection?
Parameter direction Sweep direction. DOWN|UP (default). Parameter data type is
CPD.
direction=UP sets the sweep direction from start value to stop value. 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)
direction=DOWN sets the sweep direction from stop value to start value. The sweep
measurement is performed from the stop value to the start value given by the
following formula, even if the specified start value does not satisfy it.
start = stop - step  (points -1)
Query response direction <newline>
direction returns the present setting of the sweep direction, UP or DOWN. Response
data type is CRD.
Example :SWE:DIR DOWN
:SOUR2:SWE:DIR?
[:SOURce]:SWEep:POINts
Sets the number of sweep steps for the specified channel. This command setting is
effective for both current sweep and voltage sweep.
Syntax [:SOURce[c]]:SWEep:POINts points
[:SOURce[c]]:SWEep:POINts? MINimum| MAXimum|DEFault
Parameter points Number of sweep steps. value (1 to 2500)|MINimum|
MAXimum|DEFault (default is 1). Parameter data type is
NRf+.
The points value can be expressed by the following formula, using the step value set
by the
[:SOURce]:<CURRent|VOLTage>:STEP command and the span value set by
the [:SOURce]:<CURRent|VOLTage>:<CENTer|SPAN> command.
points = span/step + 1 (where step is not 0)
points=1 sets step=0.
