SPI protocol decode
SPI protocol decode with precise time-correlation between waveforms and listing
The Keysight Technologies, Inc. SPI protocol viewer includes correlation between the
waveforms and the selected packet. The selected packet, highlighted blue row in the
listing, is time-correlated with the blue line in the waveform display. Move the blue
tracking marker in time through waveforms and the blue bar will automatically track in
the packets window. Or, scroll through the packet viewer and highlight a specific packet.
The time-correlation tracking marker will move to the associated point in the waveform.
Support for 2, 3, and 4-Wire SPI
The application supports 2-, 3-, and
4-wire SPI. Use digital channels on MSO
models to preserve analog channels for
simultaneously viewing other signals.
SPI decode embedded in waveform area
Utilize the oscilloscope waveform area to
display decode information. For SPI, minor
ticks indicate clock transitions and major
ticks show the beginning and end of each
word in the serial packet.
Full screen SPI listing
Fill the entire display with compact
protocol information using the full
screen listing. The protocol viewer
window shows the index number,
time stamp value, and data content
for each serial packet in the list.
Scroll though all decoded serial
packets to find events of interest or
errors in the transmission. Data in
the listing window can be saved to a
.csv or .txt file for off-line analysis or
documentation.

Long Time Captures using Segmented
Memory
Capture seconds to days of serial
protocol. The scope fills memory as each
acquisition sees its trigger condition.
Segmented memory uses time tags to
track time between segment acquisitions.
