Keysight Technologies Serial Bus Options for InfiniiVision X-Series Oscilloscopes Data Sheet Introduction Serial buses are pervasive in today's 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.

Keysight's InfiniiVision Series oscilloscopes are the industry's only scopes to use hardware-based decoding. Most other vendor's 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.) That's 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 scope's 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 and 4000 X-Series oscilloscopes by importing an industry-standard .ldf file. Figure 2: Symbolically decoding the CAN bus. Figure 3: Automatic "Search & Navigation" quickly finds user-specified serial bus frames/bytes of interest. After capturing a long record of serial bus communication using the InfiniiVision scope's 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 scope's front panel navigation keys. 04 | Keysight | Serial Bus Options for InfiniiVision X-Series Oscilloscopes - Data Sheet Multi-bus Analysis Using Segmented Memory to Capture Multiple Serial Bus Packets 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. Many of today's designs include multiple serial buses. Sometimes it may be necessary to correlate data from one serial bus to another. Keysight's 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. The segmented memory option for Keysight's InfiniiVision X-Series oscilloscopes (standard in 3000T, 4000 and 6000 X-Series) can optimize your scope's 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. Keysight's 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 a ddition, you can use the scope's Search & Navigation capability after a segmented memory acquisition has been performed. 05 | Keysight | Serial Bus Options for InfiniiVision X-Series Oscilloscopes - Data Sheet Serial Bus Eye-diagram and Pulse Mask Testing With the addition of the DSOX2MASK, DSOX3MASK, DSOX4MASK or DSOX6MASK mask test option, which can perform over 200,000 pass/fail tests (50,000 on 2000 X-Series) per second, you can perform eye-diagram and pulse mask testing on CAN signals on all InfiniiVision X-Series oscilloscopes. Eye-diagram mask testing on FlexRay, MIL-STD 1553, and ARINC 429 signals can be performed using an InfiniiVision 3000, 4000 or 6000 X-Series oscilloscope. Eye-diagram measurements provide a comprehensive signal quality test of the integrity of your transmitted and received signals. Keysight provides various mask files that you can download at no charge. The mask files are based on published industry mask standards and/or derived from physical layer/electrical specifications. The following CAN mask files are available: -- 125 kbps - 400 meters -- 250 kbps - 200 meters -- 500 kbps - 10 meters -- 500 kbps - 80 meters -- 800 kbps - 40 meters -- 1000 kbps - 25 meters Mask files for CAN FD are also available (3000T and 4000 X-Series only). CAN FD eye-diagrams are based on the first 10 bits of the FD phase from all frames. The following FlexRay mask test files are available: Figure 6: CAN 500 kbps mask test on 10 meter system. -- TP1 standard voltage (10 Mbps only) -- TP1 increased voltage (10 Mbps only) -- TP11 standard voltage (10 Mbps only) -- TP11 increased voltage (10 Mbps only) -- TP4 10 Mbps -- TP4 5 Mbps -- TP4 2.5 Mbps The following MIL-STD 1553 mask test files are available: -- System xfmr-coupled Input -- System direct-coupled Input -- BC xfmr-coupled Input -- BC direct-coupled Input -- RT xfmr-coupled Input -- RT direct-coupled Input Figure 7: FlexRay TP4 eye-diagram mask test.

Automated Physical Layer Conformance Testing To perform USB 2.0 signal quality testing based on USB-IF compliance standards, Keysight offers the DSOX4USBSQ or DSOX6USBSQ options on InfiniiVision 4000 or 6000 X-Series oscilloscopes. Figure 10 shows an example of the USB 2.0 real-time eye test. Also included with this option is complete signal quality test report generation in HTML format. To see the complete list of supported tests, refer to the DSOX4USBSQ/ DSOX6USBSQ signal quality test option data sheet listed at the ended of this document. Figure 10: USB 2.0 signal quality eye test based on USB-IF physical layer compliance standards. To perform physical layer conformance testing on the differential FlexRay bus, Keysight provides a PC-based software package that you can download from Keysight's website at no additional charge. If the InfiniiVision X-Series scope is licensed with the FlexRay, mask test, and segmented memory, you can perform automated physical layer tests at either receiver input or transmitter output test points. Figure 10 shows an example of the generated report from a signal integrity voting test on a 10-Mbs isolated "1" pulse. The test report includes comprehensive pass/ fail and margin analysis based on published specifications. Refer to the tables in the Specifications/Characteristics section of this document on page 17 to see the entire list of 33 available FlexRay tests that can be selected and performed using the FlexRay physical layer conformance test software package. Figure 11: FlexRay signal integrity voting test performed on an isolated "1" bit. 07 | Keysight | Serial Bus Options for InfiniiVision X-Series Oscilloscopes - Data Sheet Probing Differential Serial Buses Many of today's serial buses are based on differential signaling including USB, CAN, CAN FD, FlexRay, MIL-STD 1553, and ARINC 429. In addition, serial buses based on the RS232/UART protocol are often differential if implemented with RS422 or RS485 output drivers/ transceivers. Keysight offers a wide range of differential active probes compatible with the InfiniiVision X-Series oscilloscopes for various bandwidth and dynamic range applications. Table 1 shows the differential probes that Keysight recommends for each of the listed differential serial buses. Table 1: Recommended Probes for Differential Buses Differential bus (max bit rate) N2791A (25-MHz bandwidth) N2818A1 (200-MHz bandwidth) CAN (1 Mbps) X X CAN FD (10 Mbps data phase) X FlexRay (10 Mbps) X MIL-STD 1553 (1 Mbps) X X ARINC 429 (100 kbps) X X RS422/RS485 (10 Mbps) X X Hi-speed USB (480 Mbps) 1. N2750A (1.5-GHz bandwidth) X Note 1: The N2818A differential probe is not compatible with Keysight's InfiniiVision 2000 X-Series oscilloscopes. If you need to connect to DB9-SubD connectors on your differential CAN, CAN FD and/or FlexRay bus, Keysight also offers the CAN/FlexRay DB9 probe head (part number 0960-2926). This differential probe head, which is shown in the inset picture of Figure 12, is compatible with both the N2791A and N2818A differential active probes and allows you to easily connect to your CAN, CAN FD and/or FlexRay differential bus. The N2750A differential active probe shown in Figure 13, which is recommended for hi-speed USB 2.0 measurement applications, is based on Keysight's InfiniiMode technology. With the press of a button, you can quickly toggle between viewing the differential signal, high-side signal, low-side signal, or the common mode signal on the USB 2.0 hi-speed bus without moving probe connections. Note that this probe also comes with a built-in headlight. Figure 12: Keysight's N2818A 200-MHz differential active probe.

Data Sheet Ordering Information The various serial bus options are compatible on most models of the Keysight InfiniiVision 3000, 4000 and 6000 X-Series oscilloscopes. The entry-level 2000 X-Series oscilloscopes support only the I2C/SPI, RS232/UART, and CAN/LIN options. Existing InfiniiVision X-Series oscilloscopes can also be upgraded with these options. For most model numbers, the number after DSOX tells you to which series of oscilloscope it applies. For example, DSOX2EMBD applies to the 2000 X-Series and DSOX3EMBD applies to the 3000 X-Series.
