The coordinates of the lower left screen corner of the screen are
-4O,-22
and the upper right
screen corner of the screen are 471,233. For the graticule area, the coordinates of the lower
left corner of the graticule are
0,O
and the coordinates of the upper right graticule area are
400,200. For example, you could execute
“PU;PA
0,O;PD;PA
0,200,400,200,400,0,0,0;”
to draw
a box around the graticule area.
Because PA is an active function, executing PA causes the.active function area on the spectrum
analyzer screen to blank. lb prevent the text following PA from being written in the active
function area, execute hold (HD) after PA.
PU should be executed before the first PA command, and PA should be executed before
executing TEXT, PD, or DSPLY commands.
