CURSOR
CURSOR_SET, CRST
Command/Query
DESCRIPTION
The CURSOR_SET command allows you to position any one of
the independent cursors at a given grid location.
When you are setting a cursor position, you must specify a trace,
relative to which the cursor will be positioned. This means that
the trace must be turned on, a requirement that does not apply to
all earlier LeCroy instruments. Also new to X-Stream
instruments is that PREF and PDIF are not supported, because
each parameter has its own independent gate.

: To change only the trace without repositioning the
cursors, the CURSOR_SET command can be given with no
argument (for example, F2:CRST).
The CURSOR_SET? query indicates the current position of
the cursor(s). The values returned depend on the grid type
selected.
