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
External reference clock input is one of the methods to enable SSC
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�
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�
