Issue Details

How do I configure the PXIe-5172 to use a reference clock such as the PXIe 10 MHz backplane clock when using the Instrument Design Libraries (IDLs)?

Solution

The Configure ADC Clock VI in the IDLs for Reconfigurable Oscilloscopes can be used to set the reference clock source and reference clock rate.  The VI is found under Functions>>FPGA Interface>>Software-Designed Instruments>>Oscilloscopes>>NI PXIe-5172R.

Additional Information

Note that the LabVIEW example projects that come with the IDLs for Reconfigurable Oscilloscopes do not call this VI so by default the acquisition doesn't use a reference clock.
