Trigger (continued)
Trigger modes
Edge Triggers on a specified slope and voltage level on any channel or auxiliary trigger.
Glitch Triggers on glitches narrower than the other pulses in your waveform by specifying
a width less than your narrowest pulse and a polarity. Triggers on glitches as narrow
as 500 ps. Glitch range settings: < 1.5 ns to < 160 ms.
Line Triggers on the line voltage powering the oscilloscope.
Pattern Triggers when a specified logical combination of the channels is entered, exited,
present for a specified period of time or is within a specified time range. Each
channel can have a value of High (H), Low (L) or Don’t care (X). Triggers on patterns
as narrow as 500 ps.
State Pattern trigger clocked by the rising or falling edge of one channel.
Logic type: AND or NAND.
Delay by time The trigger is qualified by an edge. After a specified time delay between 30 ns to
160 ms, a rising or falling edge on any one selected input will generate the trigger.
Delay by events The trigger is qualified by an edge. After a specified delay between 1 to 16,000,000
rising or falling edges, another rising or falling edge on any one selected input will
generate the trigger.
Violation triggers
Pulse width Trigger on a pulse that is wider or narrower than the other pulses in your waveform
by specifying a pulse width and a polarity. Triggers on pulse widths as narrow as
500 ps. Pulse width range settings: 1.5 ns to 160 ms.
Setup/hold Triggers on setup, hold or setup and hold violations in your circuit. Requires a clock
and data signal on any two input channels as trigger sources. High and low
thresholds and setup and/or hold time must then be specified.
Transition Trigger on pulse rising or falling edges that do not cross two voltage levels
in > or < the amount of time specified.
