Scope for automotive bus analysis
Oscilloscope-based serial bus analyser checks in-vehicle serial bus protocols including FlexRay, CAN and LIN as well as providing UART, I2C and SPI trigger and analysis capabilities.
The Yokogawa SB5000 is an oscilloscope-based serial bus analyser for in-vehicle serial bus protocols including FlexRay, CAN and LIN as well as providing UART, I2C and SPI trigger and analysis capabilities The new instrument allows users to perform protocol analysis and physical layer waveform measurements simultaneously, offering the capability to debug and troubleshoot bus problems due to noise, signal quality, timing and data errors

Versatile tester for IEEE-1394 bus
The new FireWorks 1394 VK9000 from Yokogawa Martron is designed to provide engineers with a powerful 'out of the box' solution for testing systems based on the IEEE-1394 bus.
Bluetooth analysis via the USB
At the Embedded Systems Show Yokogawa Martron is introducing a new Bluetooth analyser to complement its range of test and measurement tools for communications and bus protocol analysis.
Users can efficiently evaluate the performance and verify the operation of ECUs (engine control units) and onboard semiconductor devices, as well as measuring test parameters and their conformity.
The SB5000 is based on the Yokogawa DL9710L digital oscilloscope platform, featuring 5Gsample/s sampling and a 1GHz real-time bandwidth.
The instrument has four analogue channels plus 8 or 32bit logic inputs, and offers a record length of up to 6.25Mword per channel.

Two-channel digital scope claims breakthrough
Yokogawa is claiming a price/performance breakthrough with the addition of a new two-channel instrument to its SignalExplorer family of compact digital oscilloscopes.
With the new analyser, users can observe long durations of bus data over multiple cycles, and confirm changes in timing and period.
It is possible to confirm if a FlexRay chip, for example, is functioning normally by focusing on the interface, and also to tell if specific frames such as the sync frame have definitely been sent.
Comprehensive display and analysis facilities linked with dedicated triggers make it possible to observe the relationships between waveforms and analysis results, and to check for glitches and other phenomena in the bus signal.
Analysis results and waveforms can be displayed simultaneously, and a search function allows specific events to be located and highlighted.
In addition to physical layer waveform observation and protocol analysis, the SB5000 carries out Flexray eye-diagram analysis and bus driver electrical parameter measurement.
It also provides simultaneous analysis of analogue and logic channels, and simultaneous observation of any two buses (in two zoom windows) and dual real-time analysis.
This 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.
A CAN-DBC database file can be imported, allowing symbolic triggering and analysis as well as physical value trend display.
The SB5000 has been designed for ease of use, with facilities such as a dedicated bus set-up menu and a serial bus automatic setup function.
