SB5000 Vehicle Serial Bus Analyzer (DISCONTINUED)

The SB5000 is a powerful Serial Bus Analyzer with features to support your applications.

FlexRay

Easy and efficient observation of the physical layer and simultaneous protocol analysis enable you to evaluate the performance of your FlexRay communication system. Evaluation and test through long-duration (multiple-cycle) bus observation answer questions such as whether specific frames are being transferred as designed, whether there are any "glitches" in signals, or whether any data corruption is occurring. The FlexRay FIBEX symbolic triggers, analysis and trend display functions* allow you to activate trigger and display the analysis results by physical values (Message and Signal) in conformity to FIBEX database.

In addition to Frame Start, ID, Cycle Count, Data, and other conditions, the SB5710/SB5310 serial bus analyzer allows you to trigger on CRC, BSS, and FES errors to capture physical layer voltage waveforms. The protocol analysis results list and decode displays are shown simultaneously with the waveform display which is updated in real time on every trigger (Figure 1). If a communication abnormality occurs, this helps you to identify causes including whether the problem is hardware or software related. The analysis results list can be saved to a text file in csv format. You can make a "Field Jump" in the zoom screen to the top of a specific field in a specific frame (the CRC field, for example), or search the entire range of captured data for the field's waveform by specifying field and frame conditions.

FlexRay Eye-Diagram Analysis

Figure.3 Eye Parameter Items   Figure.4 Eye diagram analysis example

With the SB5710/SB5310, you can perform mask and eye parameter tests (Figure 3) conforming to the eye-diagram evaluation methods defined by the Flex-Ray Physical Layer Conformance Test Specification. From the accumulated test pulses, you can perform the mask test to calculate the number of abnormal pulses, number of waveform samples in the abnormal portion, and their ratio, and display the results. You can also perform the same mask and eye parameter tests on a specific bit specified in the onscreen zoom box (Figure 4). Up to six mask patterns, including ones defined by the FlexRay specifications, can be stored in the unit and recalled as needed according to the type of test to be performed. You can also edit masks after recalling them.

SI Voting Procedures Analysis NEW

(World's first as a digital oscilloscope-based instrument, as of March 2009, investigated by Yokogawa)

The FlexRay Consortium Physical Layer Working Group is developing an "SI (System Integrity) Voting Procedure" in order to ensure that the Electrical Physical Layer performs correctly. With the new 4.42 firmware and later versions, the SB5000 carries out this advanced function, in addition to physical layer waveform observation and protocol analysis. Please refer to the "white paper", for detail of SI Voting Procedure and our solution.

Testing the Electrical Characteristics of the Bus Driver

The SB5710/SB5310 comes with functions for calculating parameters required for electrical characteristics tests of the bus driver (timing measurements of the transmitter and receiver operation). By simply selecting parameters for the source channel and the circuit under test in an easy-to-understand graphical menu, you can easily determine various delay times, rise/fall time, absolute value of differential voltage, and other values.

 Evaluating Fluctuations in Communication Delay and Cycle Time

The SB5710/SB5310 measures BSS bit time intervals from captured FlexRay communication data, and can also calculate relevant statistics (Figure 6). It supports time interval measurements and statistical calculation of every BSS, every BSS in frames of a specific ID, and the first BSS in specified frames or cycles.

CAN Bus

In-vehicle networks are standardized by specific use, and the optimal protocol is used for each application. The SB5710/SB5310 supports analysis of CAN, today's standard backbone network and control protocol. Like the Flex-Ray analysis functions, the instrument comes standard with abundant CAN bus triggers and robust analysis functions.

It is also equipped with dedicated CAN triggers including Start of Frame, ID, Data, Remote Frame, and Error Frame. Additionally, you can now set up to four ID and Data combination bit conditions and activate triggers based on OR relationships of these combinations. With the protocol analysis results list which is shown in a time series fashion (Figure 9), you can check each frame's analysis results (frame type, time from trigger point, ID, DLC, Data, and CRC), presence/absence of Ack, and the association with corresponding waveforms in a single screen. You can specify the type and other characteristics of fields and frames and search for corresponding waveforms in the captured CAN frame data.

Analysis and Waveform Display of Two Busses Simultaneously

You can analyze two CAN bus signals of differing conditions (for example, Hi-Speed and Low-Speed CAN) simultaneously, and display the analysis results along with waveforms. This allows verification of the correlation between the data on the upstream (backbone) network CAN bus and the downstream (sub) network. You can observe bus waveforms of different bit rates by zooming one each in the two zoom areas (Figure 10).

Symbolic Triggering, Analysis, and Trend Display

You can load physical value definition files (DBC database files with extension .dbc), enter trigger settings based on physical values (Message and Signal), and display analysis results as physical values (decoding). You can read physical values directly from waveforms, allowing increased efficiency of troubleshooting and analysis of faults in the CAN network. Also, you can specify a particular Message/Signal from the captured CAN data and display its physical values in a trend graph (Figure 12).
The dedicated PC-software for Symbol definition (Symbol Editor) allows you to convert from DBC Database file into physical (Message, Signal) value file. Then the physical value file can be imported into the SB5710/SB5310.
The Symbol definition (Symbol Editor) can be free downloaded fromhere.

LIN Bus

Comprehensive triggering, powerful analysis tools, and captured data searching functions are also provided for the LIN bus (body subnetwork). And speaking of triggers, the SB5710/SB5310 is equipped with not only Break + Synch and ID/Data (combinable) conditions, but also with a wealth of error triggers. This is one of the major features of the SB5000 series. You can capture bus waveforms when the various errors defined by the LIN protocol specifications (Parity, CheckSum, TimeOut, etc.) occur, and check those waveforms and the protocol analysis results (list) along with the error information. You can analyze both LIN revision 1.3 and 2.0 conformity data existing on the same bus line simultaneously.

Combination Triggers: Create triggers consisting of in-vehicle bus events and events on other channels
(e.g., a sensor input, or another in-vehicle bus event) (Event Interval Trigger)

Trigger on Combinations with Non-in-vehicle bus Signals Triggers can be activated on combinations of in-vehicle bus and analog signal trigger conditions. For example, you can debug a system by setting up a condition in which the trigger activates on a time difference between a LIN signal trigger condition and a signal input to another channel such as a sensor or actuator operation signal. Trigger on Combination of Two in-vehicle bus Signals You can set a condition in which a trigger activates on the time difference (delay time, etc.) between trigger conditions set on two separate in-vehicle bus networks. This is useful for verifying the complementary operation of two corresponding sub-networks. Figure.16 Event Interval trigger setting example

UART

From CPU communication data in the ECU (electric control unit) to communication signals in manufacturing facilities, communication via a general purpose UART is carried out in a broad range of fields - among them, automobile development. The SB5710/SB5310 supports general-purpose UART trigger and analysis functions. Figures 17 and 19 show examples of the UART trigger setting screen and the waveform and analysis results display, respectively.

Check Signal Conditions When Trouble Occurs with Flexible UART Triggers and Error Triggers

In addition to specifying conditions of 8-bit data (with/without parity bit) and 7-bit data + parity bit, the UART trigger function supported by the SB5710/SB5310 can search for and trigger on parity and framing errors. Analysis number, time from trigger position, binary and hexadecimal notation of data, errors, and other added information can be linked with the waveforms and displayed in the same screen as analysis results.
