No, the existing PXIe-8840 Quad-Core will be used for the test.

The main test is to confirm if NI RT Linux works okay with all the software/hardware. I have no reason to think it won't (unlike earlier tests which had obvious missing parts or errors), but would rather confirm that is the case.

I don't think we've ever had the production and spare controllers be the same model so I don't think that will be an issue. Every time we've gone to place an order the previous controller has been discontinued or unsupported.

Thanks Brian,

We will wait for your test results in December and then order one. Will you be testing a PXIe-8861 RT?

Regarding the pricing of a PXI Controller. The current spare is a PXIe-8840 Quad-Core, which is no longer recommended for new designs. The replacement is a PXIe-8861 RT.

Just for reference here is the pricing of those controllers:

PXIe-8840 Quad-Core RT = $ 10,420.00
PXIe-8861 RT = $ 8,390.00

The 8861 has a newer generation CPU with more performance over the 8840. Along with the lower pricing I don't see any reason not to purchase that instead as we've never used the ExpressCard slot for anything and that's really the only functional difference.

Currently the lead time is 80-85 days.
