6-2 PN: 10580-00319 Rev. N S412E PM
:FETCh:VVM:DATA?
Description: Query only. Returns the most recent VVM measurement results. Data
is returned as 2 or 4 comma-separated values depending upon the
measurement type, measurement format, measurement mode, port, and
the reference setting. A “–” is returned for any data that is not valid at
that instance.
Cmd Parameter: NA (query only)
Query Response: NA (comma separated values)
