keysight technologies serial bus options for infiniivision x-series oscilloscopes data sheet
introduction serial buses are pervasive in todays digital designs and are used for a variety of purposes including on- board chip-to-chip communication, cpu to peripheral control, as well as for remote sensor data transfer and control. without intelligent oscilloscope serial bus triggering and protocol decode, it can be difficult to debug these buses and correlate data transfers with other mixed signal interactions in your system. keysight technologies, inc. infiniivision x-series oscilloscopes (dsos) and mixed-signal oscilloscopes (msos) offer optional integrated serial bus triggering and hardware-based protocol decoding solutions that give you the tools you need to accelerate debug of your designs that include serial bus communication. supported protocols and features C i 2 c C spi C rs232/uart C can C can fd (except 2000 x-series) C can-dbc symbolic decode and trigger (except 2000 x-series) C lin C lin-ldf symbolic decode and trigger (except 2000 x-series) C sent (3000t, 4000 and 6000 x-series only) C cxpi (3000t and 4000 x-series only) C flexray (except 2000 x-series) C usb 2.0 low- and full-speed (4000 and 6000 x-series) C usb 2.0 hi-speed (4000 and 6000 x-series only) C usb 2.0 signal quality (4000 and 6000 x-series only) C i 2 s (except 2000 x-series) C mil-std 1553 (except 2000 x-series) C arinc 429 (except 2000 x-series) C hardware-based decoding C multi-bus analysis (except 2000 x-series) C automatic search and navigation C compatibility with segmented memory acquisition C eye-diagram mask files available for can, flexray, mil-std 1553, and arinc 429 (requires dsox2mask/dsox3mask/dsox4mask/dsox6mask mask test option) C flexray physical layer conformance test software (except 2000 x-series)
03 | keysight | serial bus options for infiniivision x-series oscilloscopes - data sheet figure 1. hardware-based decoding quickly reveals serial communication errors. figure 3. automatic search & navigation quickly finds user- specified serial bus frames/bytes of interest. figure 2. symbolically decoding the can bus. hardware-based decoding keysights infiniivision series oscilloscopes are the industrys only keysights infiniivision series oscilloscopes are the industrys only scopes to use hardware-based decoding. most other vendors scopes with serial bus triggering and protocol decode, use software post-processing techniques to decode serial packets/ frames. with these software techniques, waveform- and decode- update rates tend to be slow (sometimes seconds per update.) thats especially true when using deep memory, which is often required to capture multiple packetized serial bus signals. and when analyzing multiple serial buses simultaneously, software techniques can make decode update rates even slower. faster decoding with hardware-based technology enhances scope usability, and more importantly, the probability of capturing infrequent serial communication errors. figure 1 shows an example of a keysight infiniivision x-series scope capturing a random and infrequent can error frame. the upper half of the scopes display shows the decoded data in a lister format, along with a time-correlated decode trace shown below the waveform. symbolic trigger and decode with the dsoxt3auto, dsox4auto or dsox6auto option licensed on a 3000t, 4000 or 6000 x-series oscilloscope, you can import a .dbc file that defines your multi-node can network. the oscilloscope can then trigger on and decode the can bus symbolically as shown in figure 2. lin symbolic trigger and decode is also supported on the 3000t, 4000, and 6000 x-series oscilloscopes by importing an industry-standard .ldf file. automatic search and navigation after capturing a long record of serial bus communication using the infiniivision scopes megazoom deep memory, you can easily perform a search operation based on specific criteria that you enter. then, you can quickly navigate to bytes/frames of serial data that satisfy the entered search criteria. figure 3 shows an example of searching on captured i2c data to find all occurrences of read or write operations with no ack. in this case, the scope found five occurrences of data transfers with no ack, and marked each occurrence with a white triangle to show where in time they happened relative to the captured waveform. navigating and zooming-in on each marked byte/frame is quick and easy using the scopes front panel navigation keys. search and navigation not available for dsoxt3cxpi/DSOX4CXPI.
04 | keysight | serial bus options for infiniivision x-series oscilloscopes - data sheet figure 4. an interleaved lister makes it easier to time-correlate activity between two decoded serial buses. figure 5. segmented memory acquisition selectively captures more packets/bytes of serial bus activity. multi-bus analysis many of todays designs include multiple serial buses. sometimes it may be necessary to correlate data from one serial bus to another. keysights infiniivision 3000, 4000 and 6000 x-series oscilloscopes can decode two serial buses simultaneously using hardware-based decoding. plus they are the only scopes on the market that can also display the captured data in a time- interleaved lister display, as shown in figure 4. in this particular example, the scope has simultaneously decoded and interleaved a can and lin bus in an automotive system. packetsthe segmented memory option for keysights infiniivision x-series oscilloscopes (standard in 3000t, 4000 and 6000 x-series) can optimize your scopes memory, letting you capture more packets/frames of serial bus activity. segmented memory acquisition optimizes the number of packetized serial communication frames that can be captured consecutively. segmented memory does this by capturing just the selective frames/bytes of interest while ignoring (not digitizing) idle time and other unimportant frames/bytes. figure 5 shows an example of the oscilloscope capturing 500 consecutive hi-speed usb split packets for a total acquisition time of approximately 200 ms. capturing this much data using conventional oscilloscope acquisition memory would require 1g bytes of memory. keysights infiniivision x-series oscilloscopes are the only scopes on the market today that can acquire segments on up to four analog channels of acquisition, and time-correlated segments on digital channels (using an mso model), along with automatic hardware-based serial bus decoding for each segment. in addition, you can use the scopes search and navigation capability after a segmented memory acquisition has been performed. using segmented memory to capture multiple serial bus
