Limit Test Commands 5-73
SR780 Network Signal Analyzer
The parameter j selects Upper (0) or Lower (1) limit. The parameters x0 and y0
are the coordinates of the limit start (X0,Y0). The parameters x1 and y1 are the
coordinates of the limit end (X1,Y1). x0, y0, x1 and y1 are real numbers in the
display units.
The LSEG ? d, i command queries the endpoints and type of limit segment i. The
data is returned j, f1, f2, y1, y2[lf].
The LSEG d, i, j, x0, y0, x1, y1 command sets the endpoints of segment i to x0,
y0 and x1, y1 and the type to Upper (j=0) or Lower (j=1).
This command also sets Limit Segments to Show.
LDLT d, i
The LDLT command deletes Limit Segment Number i for display d. The value of
i may not exceed the last limit segment number. The remaining segments are
renumbered sequentially. This command is not valid for d=2 (both displays).
This command also sets Limit Segments to Show.
LSFT d, x
The LSFT command shifts all Limit Segments for display d. The parameter x is
real number. The Y coordinates of all segments are shifted by x (in display units).
This command is not valid for d=2 (both displays).
This command also sets Limit Segments to Show.
