Vehicle-bus analyser

Yokogawa’s SB5000 is an oscilloscope- based serial-bus analyser that handles FlexRay, CAN and LIN, as well as providing UART, I2C and SPI trigger and analysis capabilities. It carries out protocol analysis and physical-layer-waveform measurements simultaneously, in order to debug and troubleshoot bus problems due to noise, signal quality, timing and data errors. Based on the DL9710L digital-oscilloscope platform, it has 5G-sample/sec sampling and a 1-GHz real-time bandwidth, four analogue channels plus 8- or 32-bit logic inputs, and a record length of up to 6.25M words per channel. Users can observe long records of bus data over multiple cycles and confirm changes in timing and period. In also carries out Flexray eye-diagram analysis and bus-driver electrical-parameter measurement, with simultaneous analysis of analogue and logic channels, and simultaneous observation of any two buses (in two zoom windows) and dual real-time analysis. The analysis can include two FlexRay channels, two CAN buses operating at different speeds, or combinations of FlexRay and CAN or CAN and LIN.

Support for debugging includes the facility for changing the test scenario, with variable voltage-threshold levels and the ability to change the sample point within a bit. The instrument can import a CAN-DBC database file, allowing symbolic triggering and analysis as well as physical-value trend display.
