Chapter 9: Decode Requests
9.1 Class and Vendor Definition Files
LeCroy Analyzers use script files to decode class and vendor requests. The script files
are read when the application is initialized. After reading, the Analyzer decodes class and
vendor requests as instructed by the files.
.DEC files represent the new method of decoding. DEC stands for "decoder" and
describes both Class and Vendor requests in a C-like language. Each .dec file stores an
endpoint or request decode. When the application starts, these files are loaded
dynamically. Subdirectories are supported.
For information about legacy script decoding, see Appendix A “Legacy Script Decoding”
on page 147.
Note: The .dec files listed in the following table are in the Scripts directory under the
installation directory:
