I am using CS328A to analyze I2C lines. I am interested in triggering on a glitch on the SDA line that lasts less than 40 ns.
How should I set up the scope to do that?

Hi Elizabeth,
You use the Second Trigger by connecting the SDA line to channel A and select Use Trig 1 ~ 2 < min. Set min = 40n
Choose View | Trigger 2 Source and select Trigger 1 inverted
Set the level at whatever level is best for the glitch you want to find
That should find it for you.
Regards,
Roger
