LMR Master™ S412E Programming Manual : Vector Voltmeter Commands : :FETCh Subsystem
 
:FETCh Subsystem
This subsystem contains commands to fetch the VVM data and relative data.
:FETCh:VVM:DATA?
Description
Query only. Returns the most recent VVM measurement results. Data are returned as two or four comma‑separated values depending upon the measurement type, measurement format, measurement mode, port, and the reference setting. A “–” is returned for any data that are not valid at that instance.
