COMMAND REFERENCE
Note: Because the READ? query leaves instrument settings unaffected, it can
very well be used as follows to read a measured value within a cursor
limited acquisition area:
- Press the CURSORS key on the front panel to enable the use of
cursors.
- Set the cursor area via the CURSORS softkey menu.
