Channels
Description
Comm X Standard feature on the DSA70000B, provided as part of Option MTH on the DPO70000B and MSO70000
Series. Support for AMI, HDB3, BnZS, CMI, MLT3 and NRZ encoded signals
Bus X X Trigger on a parallel, I 2 C, or SPI bus when the specific bus value is found. (MSO70000 Series only)
Edge X X Positive or negative slope on any channel or front panel auxiliary input. Coupling includes
DC, AC, noise reject, HF reject, and LF reject
Glitch X X Trigger on or reject glitches of positive, negative, or either polarity. Minimum glitch width
is 150 ps (typical) with rearm time of 300 ps
Pattern X X Trigger when pattern goes false or stays true for specified period of time. Pattern (AND, OR, NAND, NOR)
specified for four input channels (and 16 logic channels on the MSO70000) defined as high, low, or don’t care
Runt X 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
Serial Pattern X Trigger on NRZ-encoded data up to 3.125 Gbaud (5 Gbaud with Option PTU or Option STU);
above 1.25 Gbaud requires 8b/10b encoded data. Extended with pattern lock triggering to capture
repeated acquisitions of long serial test patterns up to 6.25 Gb/s
Setup/Hold X Trigger on violations of both setup time and hold time between clock and data present on any two input channels
State X X Any logical pattern of channels (1, 2, 3) (and 16 logic channels on the MSO70000) clocked by
edge on channel 4. Trigger on rising or falling clock edge
Time-out X X Trigger on an event which remains high, low, or either, for a specified time period. Selectable from 300 ps
Transition X Trigger on pulse edge rates that are faster or slower than specified. Slope may be positive, negative, or either
Trigger Delay by
Events
X X 1 to 2 billion events
Trigger Delay by
Time
X X 3.2 ns to 3 million seconds
Width X X Trigger on width of positive or negative pulse either within or out of selectable time limits (down to 150 ps)
Window X Trigger on an event that enters or exits a window defined by two user-adjustable thresholds.
Event can be time or logic qualified
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 Option DDRA

Bus Decoding (MSO70000 only)
Characteristic Description
Parallel Data from selected channels is grouped as a parallel,
multichannel bus and displayed as a single bus value.
Display can be binary, hexadecimal, or symbolic formats
I 2 C SCLK and SDA channels are displayed as a bus per the
Inter-Integrated Circuit specification
SPI MOSI, MISO, SCLK, and SS channels are displayed as a
bus per the Serial Peripheral Interface specification
