Hi Jason,
Thank you for your response and apologies for not getting back to you quickly; I also contacted NI Support about this issue and they gave me the same response about the the 6133 not being able to support Multi-Edge Analog Triggering. For me personally I do need to capture at high rates so a manual trigger check probably wouldn't work, although I would be interested in knowing how to do this as I have yet to figure it out on my own.
Looking forward to your future posts!
