 <p class=Dropdowntext>A limit check consists of comparing the measurement

 warning and a TTL signal at the <span style="font-style: italic;"><I>USER

 is exceeded. </p>
 <p class=Dropdowntext>Upper and lower limit lines are both defined as a 
 combination of segments with a linear dependence between the measured 
 quantity and the sweep variable (stimulus variable). The limit lines can 
 be stored to a file and recalled. Data or memory traces can be used to 
 define the segments of a limit line. Moreover it is possible to modify 
 the limit lines globally by adding an offset to the stimulus or response 
 values. </p>

<h5><a name=Limit_Line_Definition></a>Rules for Limit Line Definition</h5>

<p>The analyzer places very few restrictions on the definition of limit 
 line segments. The following rules ensure a maximum of flexibility: </p>

<ul type="disc" class="whs2">
	
	<li class=kadov-p-CList><p class=List>Segments don't have to be sorted 
 in ascending or descending order (e.g. the <span style="font-style: italic;"><I>Start 
 Stimulus</I></span> value of segment no. n doesn't have to be smaller than 
 the <span style="font-style: italic;"><I>Start Stimulus</I></span> value of segment 
 no. n+1). </p></li>
	
	<li class=kadov-p-CList><p class=List>Overlapping segments are allowed. 
 The limit check in the overlapping area refers to the tighter limit (the 
 pass test involves a logical AND operation). </p></li>
	
	<li class=kadov-p-CList><p class=List>Gaps between segments are allowed 
 and equivalent to switching off an intermediate limit line segment. </p></li>
	
	<li class=kadov-p-CList><p class=List>Limit lines can be partially 
 or entirely outside the sweep range, however, the limits are only checked 
 at the measurement points. </p></li>
</ul>

<p>The following figure shows a limit line consisting of 3 upper and 2 
 lower limit line segments. To pass the limit check, the trace must be 
 confined to the shaded area. &nbsp;</p>

<p><img src="Limit_Line_Example.gif" width="507px" height="225px" border="0" class="img_whs20"></p>

 pass a DUT if no limit lines are defined. </p>
