Trigger Source CH1, CH2, CH3, CH4, EXT, EXT/5, AC Line
Pulse Width Trigger
Trigger Modes: Positive Pulse (＞,＜, ＝), Negative Pulse (＞, ＜, ＝)
Slope Trigger
Positive slope (＞,＜, ＝), Negative slope (＞,＜, ＝)

Notes:
(1) On 4-Ch models, Ch1 and Ch2 are interleaved, and Ch3 and Ch4 are interleaved. Half channel operation means that only Ch1 or Ch2 and/or only Ch3 or Ch4 is active.
(2) When timebase is 25 ns or faster and maximum data depth mode is enabled.
