:WFMOutpre?
Returns the following values. Each value represents the current settings that
a
CURVe? query will use to format the data that will be transferred from the
oscilloscope to a P C or other device (see next table for explanations):

:CURVe?
Returns the following values. Each value represents a data point:

NOTE. The returned hexadecimal data values are formatted without leading
zeroes.
NOTE. You can also use the
WAVFrm?
query, which concatenates the
WFMOutpre?
and
CURVe?
queries.
