Syntax CENT <numeric>[HZ|MHZ|V|A]
CENT?
Description Sets the sweep range center value. To set the center 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 when creating
segment 1 is the current sweep range start value and the initial value when creating an
additional segment is the sweep range stop value of the previous segment.
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.
