7 Protocol Decoding
Protocol analysis can be used by users to discover errors, debug hardware and
accelerate development easily, so as to guarantee quick and high-quality
accomplishment of projects. Protocol decoding is the basis of protocol analysis. Only
protocol analyses with correct protocol decoding are acceptable and only correct
protocol decoding can provide more error information. DS4000 provides two buses to
make common protocol decoding (including Parallel (standard), RS232 (option), SPI
(option), I2C (option), CAN (option) and FlexRay (option)) of the analog channels
(CH1 to CH4). As the decoding functions and setting methods of the two buses are
the same, this chapter only takes Decode1 for illustration.
To get the decoding option information, please refer to “Appendix A: Accessories
and Options” on page 17-1.
When you have ordered the decoding option, please refer to “Option
Management” on page 13-16 to activate corresponding option.
