csv payload

I am studying a .ala PCIe trace in version 6.30.1011 of the Keysight Logic and Protocol Analyzer software. Whenever I export the protocol viewer data to a CSV file (I use the 'CSV' toolbar button located in the protocol viewer), the payload field in the CSV file is always truncated to 60 bytes.

I have a strong need to write the entire payload to the CSV file. How do I override the 60-byte limit?

On a related matter, I'm having difficulty figuring out how to search the contents of the payload field, either whole or in part. Mostly right now I need to search the payload fields for the existence of a particular substring, of which I don't necessarily know the offset within the payload.

If I can't search the payload field as described then I'll absolutely need to export the entire payload. Or I'll have to try writing a utility to read the .ala myself, if allowed. Is there any documentation available on the format of the .ala file?

Again, I'm looking at a PCIe trace.

Thanks,
Tom

Probably the wrong group, as this applies to "RF and Microwave Network Analyzers" (like for measuring radios). Not internet or PCI networks. you might try logic and protocol analyzers group: https://community.keysight.com/community/discussion-forums/logic-and-protocol-analyzers

Tom,

"I have a strong need to write the entire payload to the CSV file. How do I override the 60-byte limit?"

- Right Click on the header at the top of the 'Payload' column, and change the 'Base' to Hex, then the full Payload data will be in your csv file.

- I assume that yoj know that the export will do all of the fields that show in the 'Packets' window, and only those fields. If you don't need all of the fields in your csv file, then delete the unnecessary columns in the display.

"On a related matter, I'm having difficulty figuring out how to search the contents of the payload field,"

- There are no general Payload search function built into the LAPA GUI. You'll have to export to csv, and do your search externally.
