Part 6: IEEE 488.2 Command Reference
CURSOR_SET, CRST
Description
The CURSOR_SET command allows you to position any one of the independent cursors at a given grid
location.
When setting a cursor position, you must specify the trace on which the cursor is positioned. This means
the trace must be turned on, a requirement not applicable to all legacy LeCroy instruments.
The legacy commands PREF and PDIF are not supported on MAUI instruments.
The CURSOR_SET? query indicates the current position of the cursor(s). The values returned depend on
the type selected.
Command Syntax
<trace>:CURSOR_SET <cursor>,<position>[. . .,<cursor>,<position>]
<trace>:= C1 to Cn, F1 to Fn, M1 to Mn, TA, TB, TC, TD
<cursor>:= {HABS, HREF, HDIF, VABS, VREF, VDIF}
<position>:= 0 to 10 DIV horizontal or -3.99 to 3.99 DIV vertical
Note: TA through TD are for backward compatibility. Although accepted, they are not returned by
queries.
Parameters are grouped in pairs. The first parameter specifies the cursor to be modified and the second
one indicates its new value. Parameter pairings can be listed in any order and restricted to those items to
be changed.
Cursor types are:
l HABS - Horizontal Absolute cursor
l HREF - Reference cursor of Horizontal Relative cursor pair
l HDIF - Difference cursor of Horizontal Relative cursor pair
l VABS - Vertical Absolute cursor
l VREF - Reference cursor of Vertical Relative cursor pair
l VDIF - Difference cursor of Vertical Relative cursor pair
The unit DIV is optional when specifying the position.
Tip: You can change the trace on which cursors are placed without repositioning the cursors by
using the CURSOR_SET command with no arguments (for example, F2:CRST).
