Is it possible to decimate or divide down the internal clock PXI 5105

Hi,

Is it possible to decimate or divide down the internal clock of a PXI 5105 ?

Thank you

It should be possible to do a decimation by n where n is a U16.  (That's what the spec told me)

If you have the card the NI-Scope driver will choose the samplerate >= desired SR and you can check it with a property or vi after a commit.

If you need to know if you can solve your measuring task to buy that card contact your local NI and ask for a quote based on your requirements.

Thank you for your reply Henrik.

I already have the card and managed to divide the clock (that was easy :D)

Hi everybody,

I come back to you because I have an other problem.

I already have one digitizer PXI 5105 in a PXIe 1073 chassis and I am planning to buy an other PXI 5105.

I will use an external trigger and external clock for my set up but the problem is that there is only 1 input (PFI 1) on each card.

It means I will use the PFI 1 on card 1 for the external clock and PFI 1 on card 2 for external trig (I will use the 16 channels for my application).

We can share signals thanks to Export signal.vi so I tried for the trigger to export to PXI trigger line 0 (I put this vi after Digital trigger.vi ), it seems to work good (I do not have any errors).

But when I try to share the external clock I have an error like "Exporting a decimated sampling clock is not supported by this device."

So my question is : Is it possible to share the external clock via the chassis's backplane to synchronize both cards?

Thank you in advance for your answers

[Henrik_Volkers]

yes that should be possible.

What other cards do you have in the chassis?

Is you chassis capable to sync to an external clock?
