Polarity
Indicates the polarity of a pulse, that is the direction of the first pulse slope.
"Positive"
Selects positive going pulses.
"Negative"
Selects negative going pulses.
"Either"
Selects both positive and negative going pulses.
SCPI command:
TRIGger<m>:GLITch:RANGe on page 460
TRIGger<m>:RUNT:POLarity on page 462
Range
Selects which glitches are identified: shorter or longer than the specified "Width".
SCPI command:
TRIGger<m>:GLITch:RANGe on page 460
Width
Sets the length of a glitch. The instrument triggers on pulses shorter or longer than this
value. The minimum width is 100 ps.
You need to know the expected pulse widths of the circuit to set the glitch width correctly.
SCPI command:
TRIGger<m>:GLITch:WIDTh on page 460
Trigger level
Sets the voltage level for the trigger event. 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 trigger level is
limited in a way so that always a hysteresis for stable trigger conditions is available.
SCPI command:
TRIGger<m>:LEVel<n>[:VALue] on page 455
3.3.1.4 Width
The width trigger detects pulses with a pulse width (duration) inside or outside the allowed
time limits. The instrument triggers if the pulse is too long to cross the specified voltage
threshold twice, if it is too short, or if it is outside or inside the time range. The pulse width
is measured at the trigger level.
Using the width trigger, you can define the pulse width more precisely than with the glitch
trigger. However, with range settings "Shorter" and "Longer" you can also trigger on
glitches.
