PXI subtistute for NI PCI-4451

[Fine]

I am looking for your PXI equivalent for the PCI-4451. I need to generate AC and measure audio with the accuracy, amplitud flatness and THD...of PCI-4451 but I have to use PXI.
May be could it be replaced using two PXI modules? Hopefully, It will not be too much overkill....

Thank You

Fine,

Your best option to replace your PCI-4451 with a PXI solution would be to use 2 boards. I would recommend the PXI-4472 for the acquisition. The 4472 will exceed the accuracy of your 4451 with 24 bits of resolution and a 120 dB dynamic range. To generate your signals if you are concerned with THD, I would recommend the PXI-5411; it will be the best suited PXI signal source.

Hope this Helps

Thank You for your help.
What if I used NI 6030E,31E would these Boards have the same amplitud flatness of the NI 4451,52 boards of +,- 1db and THD worst case -80 db on input and output source.
On another hand, Does the 5401 will meet the above spec or it has to be the 5411.

Thanks
