"Positive"
Selects positive going pulses, the width is defined from the rising to
the falling slopes.
"Negative"
Selects negative going pulses, the width is defined from the falling to
the rising slopes.
"Either"
Selects both positive and negative going pulses.
Remote command:
TRIGger:EVENt<ev>:WIDTh:POLarity on page 465
Range
Selects how the range of a pulse width is defined.
"Longer"
Triggers on pulses longer than the given "Width".
"Shorter"
Triggers on pulses shorter than the given "Width".
"Within"
Triggers on pulses inside a given range. The range of the pulse width
is defined by "±Delta" related to "Width".
"Outside"
Triggers on pulses outside a given range. The range definition is the
same as for "Within" range.
Remote command:
TRIGger:EVENt<ev>:WIDTh:RANGe on page 465
Width
For the ranges "Within" and "Outside", the width defines the center of a range which is
defined by the limits "±Delta".
For the ranges "Shorter" and "Longer", the width defines the maximum and minimum
pulse width, respectively.
Remote command:
TRIGger:EVENt<ev>:WIDTh:WIDTh on page 465
±Delta
Defines a range around the width value.
The combination "Range" = "Within" and "±Delta" = 0 triggers on pulses with a pulse
width that equals "Width".
The combination "Range" = "Outside" and "±Delta" = 0 means to trigger on pulse
widths ≠ "Width".
Remote command:
TRIGger:EVENt<ev>:WIDTh:DELTa on page 465
7.4.5 Runt trigger
Access: "Menu" > "Trigger" > "Setup" tab > "Type = Runt"
A runt is a pulse lower than normal in amplitude. The amplitude crosses the first
threshold twice in succession without crossing the second one. For example, this trig-
ger can detect logic, digital, and analog signals remaining below a specified threshold
amplitude because I/O ports are in undefined state.
