T Clock Exemple for RFSA drivers

[DanyAllard]

Hi I'm searching an exemple how to use T Clock with RFSA driver. Anyone have somting to share about that?

Thanks

Hi Dany,

What exactly will you use TClk for? Do you want to synchronize several RF devices or do you have other PXI modules that you want to synchronize with the RFSA? It would be helpful if you can share more information on what you want to accomplish and what devices you are using. If you want to reference all the devices to the same reference clock and synchronize their start triggers you can do so using TClk. However if you need to synchronize multiple RF devices, depending on your device, that might not be possible. This KB explains the limitations. I hope this is helpful; please post back if this is not the case.

I want to synchronize 2x5661 to get tight signal recording. Currently I use RFSA drivers to do the recording on each side but now I need to start recording at the same time using TCLK but TCLK is available only for NI-SCOPE. What I need to do to get this working.

Thanks

Hi Dany,

In this case you won’t be able to get tight synchronization between the two 5661 modules due to the fact that each one has its own local oscillator, as explained in the KB I linked in my previous post. You can though start both acquisitions at the same time by sharing the start trigger and you can also reference to the same reference clock. You can use the niRFSA Export Signal vi to route the trigger signal to a specified output and use the niRFSA Configure Digital Edge Star Trigger vi to start the acquisition in both devices. I’m sorry because this might not cover all your requirements but I hope this is helpful,
