Search & Zoom
When waveform acquisition is stopped, you can search the displayed waveforms (within
the display record length. See appendix 1.) and display the waveforms that match the
search conditions expanded on the screen.
Edge Search <For the setup procedure, see section 10.4>
Search is performed by counting the number of times the waveform goes above or below
(rising or falling) a specified level.

Hysteresis
Serial Pattern Search <For the setup procedure, see section 10.4>
Search is performed on whether the serial status pattern of the waveform (status pattern
of the waveform that changes over time) is the same as the status pattern set in
advance. You can also set whether the timing used to detect the waveform status (up to
64 statuses) is synchronized to a selected clock signal or is performed at certain time
intervals.
