I had a chassis (PXIe-1082) with a single channel PXIe-5413 in and I was able to set the reference clock of the device to use the PXIe_clk100 using the "ClocksReferenceClocks" object and setting the "Source" to PXIe_clk100 (Matlab and FGEN instrument drivers).
I have added a second PXIe-5413 to the chassis which has two channels. My previous code, even for the previously installed PXIe-5413 doesn't work as the 'Source' property doesn't exist anymore.
Other functions possible within the FGEN instrument drivers are "Configurefunctionsconfigureclock" with the 'ConfigureReferenceClock' as an object and In the "Obsolete" function the "ConfigureRefClockSource".
Has anyone experience this problem before? Was I using the wrong function/object to set my reference clock previously? Any suggestions on which setting will work now without trying all of them?
