Data Sheet
Trigger Modes
Mode Description
Edge Positive or negative slope on any channel or front-panel
auxiliary input. Coupling includes DC, AC, noise reject,
HF reject, and LF reject
Glitch Trigger on or reject glitches of positive, negative, or
either polarity. Minimum glitch width is down to 170 ps
(typical) with rearm time of 250 ps (for DPO7254 or
DPO7354)
Width Trigger on width of positive or negative pulse either
within or out of selectable time limits (down to 225 ps)
Runt Trigger on a pulse that crosses one threshold but fails to
cross a second threshold before crossing the first again.
Event can be time or logic qualified
Time-out Trigger on an event which remains high, low, or either,
for a specified time period. Selectable from 300 ps
Transition Trigger on pulse edge rates that are faster or slower
than specified. Slope may be positive, negative, or
either
Setup/Hold Trigger on violations of both setup time and hold time
between clock and data present on any two input
channels
Pattern Trigger when pattern goes false or stays true for
specified period of time. Pattern (AND, OR, NAND,
NOR) specified for four input channels defined as high,
low, or don't care
State Any logical pattern of channels (1, 2, 3) clocked by edge
on channel 4. Trigger on rising or falling clock edge
Window Trigger on an event that enters or exits a window
defined by two user-adjustable thresholds. Event can
be time or logic qualified
Trigger Delay by Time 5 ns to 250 s
Trigger Delay by Events 1 to 10,000,000 events
Comm Provided as part of Opt. MTM. Support for AMI, HDB3,
BnZS, CMI, MLT3, and NRZ encoded signals
I 2 C, SPI, and RS-232 Protocol trigger on DPO7054, DPO7154, DPO7254,
or DPO7354
CAN Basic protocol trigger on DPO7054, DPO7154,
DPO7254, or DPO7354 as part of Opt. LSA. Optional
ATM-1 module adds LIN and advanced CAN triggering
Serial Pattern
(Option PTM)
Captures serial data stream with built-in clock recovery
for NRZ standards up to 1.25 Gb/s. Extended with
pattern lock triggering to capture repeated acquisitions
of long serial test patterns
Search and Mark Events
Event Description
Basic Mark any events and document waveforms. Search
positive, negative slopes or both on any channels.
Event table summarizes all found events. All events are
time stamped in reference to trigger position. Users can
choose to stop acquisitions when an event is found
Advanced Search glitches or runts, as well as transition rate, pulse
width, setup and hold, time-out, window violations,
or find any logic or state pattern on any number of
channels. Search DDR Read or Write bursts with Opt.
