Hi,
I am using PXIe-5673 and PXIe-5663 for my project. I want to synchronie the two local oscillators (5652).
Can I connect the CLK OUT terminal of the digitizer (5622) to the CLK IN terminal of the IQ Signal Generator (5450)? This way the Local Oscillators of 5663 and 5673 will share same clock.
Can someone please let me know if I can follow this approach?
Thanks so much

Hello Sharmi,
To synchronize the 5663 and 5673, we generally use the internal clock on the 5652 for both the VSA and VSG. Essentially, you need to connect your hardware as shown in this diagram:
And you need to make sure that you export the reference clock from the VSG to the VSA:
Thanks for the question,
