Error -200414 Requested Sample Clock Source is Invalid in LabVIEW When Trying to Synchronize C Series Modules

Updated Nov 2, 2023

Issue Details

When I'm trying to share the sample clock with one of my C series measurement cards in DAQmx to ensure synchronized measurement I receive the following error: 

Error -200414 occurred: Requested sample clock source is invalid.

Solution

This error can happen when you are trying to share the sample clock with a DSA ADC module. Please see the various ADC-s used in NI devices on this link. For only SAR ADC-s the sample clock sharing and a start trigger is sufficient for synchronized operation, but for DSA ADC-s the situation is a little more complex. On this link you can find detailed guidance about how to synchronize the different ADC modules in different combinations. It will also cover how to synchronize SAR and DSA devices while sampling with a different sample rate.
