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.
