Pinpoint Triggers
Pinpoint Trigger Selections
Trigger Type Trigger Conditions
Edge Trigger on a rising or falling edge, as de fi ned by the slope control. Coupling choices
are DC, AC, LF Reject, HF Reject, and Noise Reject.
Glitch Trigger on a pulse narrower (or wider) than the speci fi ed width or ignore glitches
narrower (or wider) than the speci fi ed width.
Width Trigger on pulses that are inside or outside a speci fi ed time range. Can trigger
on positive or negative pulses.
Runt Trigger on a pulse amplitude that crosses one threshold but fails to cross a second
threshold before recrossing the
fi rst. Can detect positive or negative runts, or only
those wider than a speci fi ed width. These pulses can also be quali fi ed by the logical
state of other channels (four-channel models only).
Window
Trigger when the input signal rises above an upper threshold level or falls below a
lower threshold level. Trigger the instrument as the signal is entering or leaving the
threshold window. Qualify the trigger event in terms of time by using the Trigger
When Wider option, or by the logical state of other channels using the Trigger When
Logic option (four-channel models only).
Timeout
Trigger when no pulse is detected within a speci
fi ed time.
Transition
Trigger on pulse edges that traverse between two thresholds at faster or slower rates
than the speci
fi ed time. The pulse edges can be positive or negative.
Serial Trigger on 64-bit serial pattern at data rates up to 1.25 Gb/s (TDS6000B and
TDS6000C) and 40-bit serial patterns up to 3.125 Gb/s (TDS6000C only). Requires
Option ST.
Pattern Trigger when logic inputs cause the selected function to become True or False. You
can also specify that the logic conditions must be satis
fi ed for a speci fi c amount of
time before triggering.
State Trigger when all of the logic inputs to the selected logic function cause the function to
be True or False when the clock input changes state.
Setup/ Hold Trigger when a logic input changes state inside of the setup and hold times relative
to the clock.
Comm Trigger in conjunction with mask testing on communications codes and standards.
The controls work together to de
fi ne the parameters for the trigger event (available
with Option SM).
