Measurement and Internal Operations_____________________________
Measurement methods are normal measurement (start recording when mea-
surement starts) and trigger measurement (start recording when trigger criteria
are satisfied).
In this manual, “Measurement start” means the instant when you press the
START key, and “Recording start” means the instant when recording begins on
the waveform screen.
Trigger settings: "Chapter 6 Trigger Settings" (⇒ p. 129)
• Select the Trigger mode to record upon either single or repeating trigger
events. (⇒ p. 132)
• Enable pre-triggering if you want to capture data measured prior to trigger
events. (⇒ p. 134)
