Hi NI Team,
I've recently purchased the NI 6570 PXI module and I'm learning to use it now. The goal is to use the module to measure a device with an SPI interface. I've been reviewing some pages and example programs along with the Digital Pattern Editor (ultimately I'm going to be using python for working with the 6570 and so I'm using the NIDigital python module).
It seems that if you want to burst any sort of pattern you're going to have to create it in the .digipat format. Is that a true statement? Is there a way to command the 6750 to send patterns without first creating the .digipat file? I ask this because:
I was hoping to use this template from the Digital Pattern Editor:
Where perhaps the "D" in vectors 5&6 are something I can dynamically alter. Is that the case? If not, may I request a little more information on what is going on in that point of sending commands?
Thank you for your time,

Since you're new to using the 657x instrument, I would recommend taking up this training - https://learn.ni.com/learning-paths/device-testing-with-digital-pattern-instruments
It will save you several weeks of learning curve and the majority of your current questions will be answered.

Thank you for your message! It helps a lot. For the IO part, I was considering read and write operations on the hard drive. I was thinking the flow would have to be:
And would be done dozens of times depending on dynamic data. And so the write and read operations of the disk will eventually be the bottleneck of testing as it would be slower than actually bursting the pattern. Of course, as you explained, this isn't the way to work with the instrument.
Thank you for the link, I will try to see if I have access to this training.
