Description<br />

The DSPLY comm<strong>and</strong> displays the value of a variable anywhere on the spectrum analyzer<br />

display. Use the PU, PR, <strong>and</strong> PA comm<strong>and</strong>s to position the variable on the screen. (You do not<br />

have to specify the PU or PD comm<strong>and</strong>s; DSPLY can display the data independent of PU or PD<br />

comm<strong>and</strong>s.)<br />

The coordinates given relate to the lower left corner of the first character. For example,<br />

“PU;PA 50,lOO;DSPLY CF,13.3;” would display the center frequency with the first digit to<br />

the right <strong>and</strong> above the point represented by 50, 100. (Position the pen before executing the<br />

DSPLY comm<strong>and</strong>.)<br />

If the number to be displayed is larger than the field width, the number is displayed in<br />

scientific notation.<br />

The DSPLY comm<strong>and</strong> also places the value of the variable in the display list. See “DA” for<br />

more information about the display list.<br />
