Industry’s Leading Hardware Serial Trigger (Continued)
Industry’s only 12.5 Gb/s hardware serial trigger
with SSC tracking at oscilloscope channel
The Infiniium V-Series hardware serial trigger’s speed covers
most common high-speed serial bus rates starting from
480 Mb/s up to 12.5 Gb/s, which include USB 2.0, USB 3.1, PCI
Express Gen 3, HDMI 2.0 and SAS-3 applications. Most of these
applications also support spread spectrum clocking (SSC) where
the high-speed signal is modulated, and the V-Series’ hardware
serial trigger is able to track the SSC at the oscilloscope input
channel or with the use of an external reference clock input. The
hardware serial trigger will recover and generate a sub-rate clock
when locked to the signal.
External reference clock input is one of the methods to enable SSC
tracking by the hardware serial trigger.
Industry’s first PRBS error detector
The PRBS error detector can trigger and display the bit error of
the PRBS-7, 15, 23, and 31 signals. It identifies the error when
the pattern does not match the expected PRBS pattern that has
been set in the oscilloscope. When the next error happens, the
oscilloscope will replace the display with the next bit error. This
allows you to discover if the error is related to the bit pattern,
which is related to inter-symbol interference (ISI). The hardware
serial trigger provides an eye view plot to show the signal quality
of the signal received.
PRBS error detector triggers on a bit error in the PRBS-15 signal. An
eye view plot (bottom left) is provided to show the quality of the signal
received by the hardware serial trigger. The hardware serial trigger
works when there is enough eye opening (blue area) to discern the bit
value.
Use with InfiniiScan’s software serial trigger for up
to 240-bit sequence trigger
The hardware serial trigger can be combined with InfiniiScan’s
software event trigger to provide a two-stage trigger for up to
240-bit sequence. This is particularly powerful for the V-Series
with its deep acquisition memory (up to 2 Gpts), providing long
trace capture of 25 ms at the high resolution sampling rate of
80 GSa/s. The hardware first finds the 160-bit event condition
and then uses InfiniiScan for an additional 80-bit event trigger.
The InfiniiScan event trigger is not limited to bit sequence search.
Other search functions such as zone touch trigger allow you to
visually draw zones on the oscilloscope display as a second stage
trigger.
Hardware serial trigger and InfiniiScan’s software serial trigger provide
up to 240-bit sequence trigger.
