Pinpoint Trigger Selections
Trigger Type Trigger Cond itions
Edge
Trigger on a rising or falling edge, as defined by the slope control. Coupling choices
are DC, AC, LF Reject, HF Reject, and Noise R eject.
Glitch
Trigger on a pulse narrower (or wider) than the specified width or ignore glitches
narrower (or wider) than the specified width.
Width
Trigger on pulses that are inside or outside a specified 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 first. Can detect positive or negative runts, or only
those wider than a specified width. These pulses can also be qualified by the logical
state of other channels.
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 l eaving 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.
Timeout
Trigger when no pulse is detected within a specified time.
Transition
Trigger on pulse edges that traverse between two thresholds at faster or slower rates
than the specified time. The pulse edges can b e positive or negative.
Serial Trigger on 64-bit serial pattern at data rates up to 1.25 Gb/s. Requires Option PTM.
This mode includes clock recovery. Push set 50% to reinitialize clock recovery.
Pattern
Trigger when logic inputs cause the selected function to become True or False. You
can also specify that the logic conditions must be satisfied for a specificamountof
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 defi ne the parameters for the trigger event (available
with Option MTM). This mode includes clock recovery. Push set 50% to reinitialize
clock recovery.
Video
Trigger on specified fields or lines of a composite video signal. Only composite
signal formats are supported.
SPI Trigger on Serial Peripheral Interface (SPI) signals.
I
2
C Trigger on Inter-IC Control ( I
2
C) signals: start, stop, repeated start, missing
acknowledge, address, data, and address and data.
RS-232 Trigger on RS-232 signals.
CAN Trigger on CA N Bus signals.
