3.6 Starting and Stopping Measurement
82
Measurement methods are normal measurement (start recording when measurement starts) and trigger
measurement (start recording when trigger criteria are satisfied). In this manual, "Measurement start"
means the instant when you click
[START], and "Recording start" means the instant when recording begins
on the waveform screen.
• Select the Trigger mode to record upon either single or repeating trigger
events.(p.191)
• Enable pre-triggering if you want to capture data measured prior to trigger
events.(p.204)
When the trigger mode is set to [Repeat] or [Auto] (Memory function only), the
number of trigger events is shown in the top part of the screen (Storage Counter).
See: "Explanation of Screen Contents" (p.20)
