PXI 5105 true bandwidth

[Bob_French]

The PXI-5105 specification states:

60 MHz real-time sampling

60 MHz bandwidth

Clearly the two specifications are not compatable.  What is the true PXI-5105 bandwidth?

Hello Bob,

Thank you for bringing this issue to the forums. The reason for this statement, "60 MHz Analog Bandwidth," is to tell us that we have good signal intergrity up to 60 MHz, and hence our 3dB point is not at 30 MHz (allowing us to sample at 30 Mhz without significant attenuation). According to the Frequency Response graph below, when we have our Antialiasing Filter, we have a bandwidth of 24MHz and otherwise we can sucessfully sample up to a bandwidth of 30 Mhz. Also, you can see our Full Bandwith of 150MHz. 

This is found in the 5105 Manual: http://www.ni.com/pdf/manuals/374403g.pdf

Thank you,
