3. Peak Search  
Set the peak search condition. The available options are Maximum and Para.  
  If Max is selected, the system searches for the maximum on the trace.  
  If Para is selected, the system searches for the peak that meets the 
parameter condition on the trace. 
Note: This setting applies only to the peak search executed by pressing Peak 
at the front panel; while other searches such as Next Peak, Peak Right, Peak 
Left and Min Search are all based on the Para. 
 
 
Peak Table 
 
Open the peak table (in the lower window) which lists the peaks (with frequency 
and amplitude) that meet the peak search condition. Up to 10 peaks can be 
displayed in the table.
