CLRJSOX Clear Box
Description
lb use CLRBOX, you must specify the rectangular area of the box. You can also specify
whether the annotation or trace planes are to be cleared.
Specifying the rectangular area of the box
You specify the rectangular area by specifying the coordinates of the lower left corner (xl, yl)
and the upper right corner (x2, y2) of the rectangle in display units. (The cleared area includes
the xl, yl, x2, and y2 coordinates).
Specifying the annotation or trace plane
You can specify whether the annotation or the traces are to be cleared by specifying an “A”
for the annotation plane or a “T” for the trace plane. If you specify the annotation plane,
everything but the trace display will be cleared. If you specify the trace plane, the trace
display will be cleared. (The cleared trace display can be overwritten if the spectrum analyzer
is in the clear-write mode, however.) If you do not specify the annotation or trace plane, both
the annotation and trace planes are cleared.
CLRBOX affects only the spectrum analyzer display and printing of the spectrum analyzer
display. CLRBOX does not change the plot of the spectrum analyzer display; the area that is
cleared by CLRBOX will still be plotted.
