Where are the Measurement Library Functions from NI-SCOPE being Calculated?

Hardware

  • PXI Oscilloscope

Issue Details

Are the processing steps of the Measurement Library processed on the FPGA of the scope or transfered to the system controller and calculated there?

Specifically for example in the case of the PXIe-5172.

Solution

The Measurement Library does all the processing on the host aka "the controller". This is true for all our oscilloscopes and the code is shared.

More specifically, the math is done in user mode in the same process as the customer application. This means that this processing competes for resources with other things running on the computer.
