"ti
≠
t"
Triggers on pattern state durations unequal to the "Time t", if "Varia-
tion"
Δ
t = 0.
If "Variation"
≠
0: this setting triggers outside a range t
±Δ
t.
"Inside, Out-
side"
Triggers on pattern state durations inside or outside a range specified
with "Time t1" and "Time t2".
This method is an alternative setting to the range definition with "Time
t" and "Variation". The values are interdependent. "Variation" and "Time
t" are adjusted If you change t1 and t2, and vice versa.
"Timeout"
Defines how long the result of the pattern condition must be true. The
instrument triggers at "Time t".
Remote command:
Time t
Sets the reference time, the nominal value for comparisons ti<t, ti>t, ti=t, ti
≠
t and timeout
Remote command:
Time t1, Time t2
Set the lower and upper time limits defining the time range if "Inside" or "Outside" is set
for comparison. "Time t" and "Variation" are adjusted accordingly.
Variation
Sets a range Δt to the reference "Time t", if comparison is set to "ti=t" or "ti
≠
t". The
instrument triggers on pulses inside or outside the range ti±Δt.
Remote command:
3.3.2.7
Rise Time / Fall Time
The rise time trigger, also known as slew rate or transition trigger, can detect fast or slow
rising or falling edges selectively. It triggers on edges, if the rise or fall time from the lower
to higher voltage level (or vice versa) is shorter or longer as defined, or inside or outside
a specified time range. The trigger finds slew rates that are faster than expected or per-
missible to avoid overshooting and other interfering effects. It also detects very slow
edges violating the timing in pulse series.
Polarity
Sets the edge, the transition time of which is to be analyzed:
"Rising"
