Setting Traces – TRACE Key 
The  TRACE key is used to configure the data acquisition for measurement and the analysis of the 
measurement data. 
The R&S FSL is capable of displaying up to six different traces at a time in a diagram. A trace consists 
of a maximum of 501 measurement points on the horizontal axis (frequency or time). If more measured 
values than measurement points are available, several measured values are combined in one 
measurement point.  
The trace functions are subdivided as follows: 
• Display mode of trace (Clear Write, View and Blank). For details on trace modes see "Trace mode 
overview" on page 4.40. 
• Evaluation of the trace as a whole (Average, Max Hold and Min Hold). For details on trace modes 
see "Trace mode overview" on page 4.40. For details on averaging see "Description of the 
averaging method" on page 4.41. 
• Evaluation of individual measurement points of a trace. For details on detectors see "Detector 
overview" on page 4.42.
