Issue Details

I know that NI PXIe-5842's center frequency is minimum 30MHz.

But if we set the span to 60MHz, can we measure signals near 0Hz?

Solution

Anything below 30 MHz is not trustable and there is no calibration data and NI have no obligation to ensure that any behavior you see below 30 MHz on a module today will be the same on other modules or will not change in the future.
