:STEP? MAXimum Query highest allowable level
Description This command is used to specify a step size for a linear sweep.
When the sweep is started, the source level changes in equal steps
from the start level to the stop level. A measurement is performed at
each source step (including the start and stop levels).
NOTE This command cannot be used for a logarithmic sweep. Use the :POINTs
command to set the source-measure points for a log sweep.
To avoid a setting conflicts error, make sure the step size is greater
than the start value and less than the stop value.
The number of source-measure points in a linear sweep can be cal-
culated as follows:
Points = [(Stop - Start) / Step] + 1|
Points = (Span / Step) + 1
An alternate way to set the source-measure points in a linear sweep
is to simply specify the number of source-measure points in the
sweep using the :POINts command.
