History Search
When signal acquisition is stopped, you can search for history waveforms that meet 
specified conditions.
Zone Search  ►For the procedure, see sections 11.2 to 11.4
You can search for history waveforms that pass or do not pass a specified search zone. 
There are three types of search zone, as follows.
•  Waveform Zone
  Set a zone on the screen using a waveform.
•  Rectangular zone
  Set a rectangular zone on the screen.
•  Polygonal zone
  Load a polygonal zone created on a computer
.
Waveform Parameter Search  ►For the procedure, see sections 11.5 to 
11.7
From the history waveforms, you can search for waveform meeting or not meeting 
specified search parameter conditions. There are three types of search parameter, as 
follows.
•  Waveform Parameter
  Search by values of the automated measurement of waveform
 parameters.
•  FFT Parameter
  Search for FFT waveform marker measurement values, maximum values in a 
specified sector
, or computation values using FFT measurement values.
•  XY Waveform Measurement Value
  Search for a computation value using the area of an XY
 waveform or an area.
