System Commands 5
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.
Note 1: When the oscilloscope is in the dual grid mode, traces are
assigned to either the upper grid (EA, MC, FE, C1, C3~) or lower
grid (EB, MD, FF, C2, C4~). The trace specified determines
whether a vertical cursor will be placed relative to the upper or
lower grid.
In quad grid mode~ each channel is permanently assigned to its
respective grid with C1 at the top and C4 at the bottom. All other
traces may be re-positioned anywhere on the screen using the ver-
tical position control.
Note 2: If the parameter display is turned on (or the pass/fail dis-
play or the extended parameters display), the parameters of the
specified trace will be shown unless the newly chosen trace is not
displayed or has been acquired in sequence mode (these condi-
tions will produce an environment error, see Table 6, page 84). To
only change the trace without repositioning the cursors, the CUR-
SOR SET command may be given with no argument, (e.g.
EB:CRST).
