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.

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.

The SB5710/SB5310 also comes standard with trigger and analysis functions for the I²C and SPI general-purpose serial buses that are widely used as internal buses in car navigation and car audio systems. Figure 20 shows an example of measurement on an I²C bus, and Figure 21 gives an example of simultaneous display of waveform capturing and the analysis results list on the SB5710/SB5310.
The various kinds of serial bus analysis functions required in the automobile development process come standard on the SB5710/SB5310; a single instrument supports development and evaluation in a variety of scenarios.
