Triggers on a specified slope (rising, falling or alternating between rising and falling) and voltage
level on any channel or auxiliary trigger.
Trigger on rising or falling edges that cross two voltage levels in > or < the amount of time specified.
Edge transition setting from 250 ps.
The trigger is qualified by an edge. After a specified time delay between 10 ns to 10 s, a rising or
falling edge on any one selected input will generate the trigger.
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.
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 125 ps. Glitch range settings:
< 250 ps to < 10 s.
Triggers on the line voltage powering the oscilloscope.
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 125 ps. Pulse width range settings:
250 ps to 10 s. Trigger point can be “end of pulse” or “time out”.
Triggers on a pulse that crosses one threshold but fails to cross a second threshold before crossing
the first again. Can be time qualified with minimum setting of 250 ps.
Trigger when a channel stays high, low, or unchanged for too long. Timeout setting: from 250 ps to
10 s.
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 or times out. Each channel can have a
value of High (H), Low (L) or Don’t care (X).
Pattern trigger clocked by the rising, falling or alternating between rising and falling edge of one
channel.
Triggers on setup, hold, or setup and hold violations in your circuit. Requires a clock and data signal
on any two inputs (except aux or line) channels as trigger sources. Setup and/or hold time must
then be specified.
