Title: Siglent SDS1104X-E LIN decoder doesn't decode frames with zero-length response
Post by: Yannik on February 01, 2019, 11:21:22 pm

I've recently purchased a Siglent SDS1104X-E to analyze a LIN-Bus.

Even though the scope works fine in general, I found a bug in the LIN decoding. Frames with 0-length frame response data are not decoded correctly:

You can see the Sync Break Field, the Sync Break Delimiter, Sync Field and the Identifier in this screenshot. The frame response has length zero.

Normally, the data is decoded like this (bottom part of the screen):

When examining a unknown protocol, it's pretty important to see all the data transmitted on the bus, including frames with a 0-length response. (Sometimes, especially those!)

Anyone else who experienced this bug?
What would be the best way to report this to siglent?

I got a reply from siglent eu today. They will forward the issue to their chinese developers. I'll report back once I get any news on this.
