SPAN
Syntax SPAN <numeric>[HZ|MHZ|V|A]
SPAN?
Description Sets the span value of the sweep range. To set the span value of each segment when
creating the list sweep table, also use this command.
Parameters
Note that, if you use this command to create a segment, the initial value is 0 regardless of
the sweep parameter.
If the specified parameter is out of the allowable setting range, the minimum value (if the
lower limit of the range is not reached) or the maximum value (if the upper limit of the
range is exceeded) is set.
