Without further ado, here are my notes (to myself) for how to set up the software to make the logic analyzer do what I want. And a bonus youtube video at the end illustrating all of it.
Change mode to "Record"
Click + to add channels
If adding multiple lines, choose Bus, otherwise Signal
If using trigger, change trigger dropdown to 'normal'.
Else, set it to 'none'.
Choose Rate (I like 1 MHz minimum)
Set 'base' to how much time you want to capture. 'Samples' will be auto computed. Note, streaming doesn't seem to be supported, so the higher the sample rate, the smaller the sample size.
If using trigger,
Set trigger to 10% or less. 10% will capture 10% of data before the trigger happened which is often the most useful for me.
