"Lowpass"
Frequencies higher than the "Cut-off" frequency are rejected, lower fre-
quencies pass the filter.
You can adjust the "Cut-off" frequency, the default is 50 kHz.
SCPI command:

Sets the trigger level automatically to 0.5 * (MaxPeak – MinPeak). The function is not
available for an external trigger source.

Qualify
Enables the settings for trigger qualification that are defined in the "Qualification" tab.
Qualification adds additional trigger conditions considering the logic states of other digital
channel signals.
The checkmark is only active if at least one qualification channel is selected.
Qualification is available for many trigger types: Edge, Glitch, Width, Runt, Window,
Timeout, and Interval.
Qualification is not possible for the R-event.
See also: chapter 3.3.2, "Trigger Qualification", on page 77.
Robust trigger
The "Robust trigger" setting is relevant for all trigger types with an event condition that is
based on the time difference between a rising and a falling edge. These trigger types are:
glitch, width, runt, timeout, window, data2clock, pattern, and serial pattern. It avoids an
undefined state of the trigger system that might occur due to hysteresis, for example,
when triggering on the envelope of a modulated signal.
