"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 1260
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 1261
±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] on page 1255
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
remaining below a specified threshold amplitude because I/O ports are in undefined
state.
