Issue Details

I want to synchronize multiple NI PXIe-5668R Vector Signal Analyzers for phase synchronized applications. Can I use NI-TCLK to achieve this objective? I am unable to find any-NI TCLK based example for NI-RFSA drivers which supports NI PXIe 5668R as well. 


NI PXIe-5668R support was added in NI-RFSA 14.1 or later driver versions. However, NI-TCLK support for NI PXIe-5668R Vector Signal Analyzer has been added in NI-RFSA 18.1 or later driver versions. If you are currently not able to find any example which uses NI TCLK for NI PXIe 5668R RFSA Synchronization, upgrade your NI RFSA version to minimum NI-RFSA 18.1 or later.
