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. DS2000A provides two buses
to make common protocol decoding (including Parallel (standard), RS232 (option),
I2C (option) and SPI (option)) of the analog channels (CH1 or CH2). 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 18-1.
When you have ordered the decoding option, please refer to
Option Management
on page
14-13 to activate corresponding option.
