Chapter 8 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. MSO2000A/DS2000A
provides two buses to make common protocol decoding (including Parallel (standard),
RS232 (option), I2C (option), SPI (option) and CAN (option)) of the analog channels
(CH1 or CH2) and digital channels (D0-D15). 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 the introduction in
“Appendix A: Accessories and Options”.
When you have ordered the decoding option, please refer to the introduction in
“Option Management” to activate corresponding option.
