8 Protocol Decoding
Protocol analysis can be used to discover errors, debug hardware and accelerate
development of digital I/O circuits more conveniently than analog troubleshooting
alone. Protocol decoding is the basis of protocol analysis and can provide more error
information as well. The MSO4000/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 purposes.
To get the decoding option information, please refer to “
Appendix A: Accessories
and Options” on page 18-1.
When you have ordered the decoding option, please refer to “
Option
Management” on page 14-16 to activate the corresponding option.
