"Negative" Triggers on negative going pulses.
Remote command:
TRIGger<m>:WIDTh:POLarity
on page 1394
Range
Selects how the range of a pulse width is defined:
"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.
"Shorter" Triggers on pulses shorter than the given "Width".
"Longer" Triggers on pulses longer than the given "Width".
Remote command:
TRIGger<m>:WIDTh:RANGe
on page 1394
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<m>:WIDTh:WIDTh
on page 1395
±Delta
Defines a range around the given 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".
Trigger level
Sets the voltage level for the trigger condition. You can also drag the trigger level
marker on the display (TA or TB on the right edge of the display). The range of the trig-
ger level is limited in a way so that always a hysteresis for stable trigger conditions is
available.
Remote command:
TRIGger<m>:LEVel<n>[:VALue]

6.3.5 Runt
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. In addition to the
threshold amplitudes, you can define a time limit for the runt in the same way as for
width triggers. For example, this trigger can detect logic, digital, and analog signals
