CURSOR
CURSOR_SET, CRST
Command /Query
DESCRIPTION
The CURSOR_SET command allows the user to
position any one of the eight independent cursors at
a given screen location. The positions of the cursors
can be modified or queried even if the required
cursor is not currently displayed on the screen.
When setting a cursor position, a trace must be
specified, relative to which the cursor will be
positioned.
The CURSOR_SET? Query indicates the current
position of the cursor(s). The values returned
depend on the grid type selected.

COMMAND SYNTAX

>,<position>,<cursor> ,<position>]
< trace > : = {C1, C2, C3, C4}
<cursor> : =
{ VREF,VDIF,TREF,TDIF,HRDF,HDIF}
<position>(horizontal)：= {0.02 to 13.98 DIV }
<position>(vertical)：= {0.02 to 7.98 DIV}
Note:
1. The horizontal position‘s value is related to the
size of screen. For SPO models, the position‘s
value is in the range of 0.02 to 13.98. And in
non-SPO models it‘s in the range of -8 to 8. If the
value is in the range of 0.02 to 13.98, you need
