How to configure the amplitude on the CLK OUT coming from NI PXI-6652?

In the NI PXI-6652 specification document it clearly says under CLK OUT characteristics that "Amplitude, Software Configurable". But I couldn't figure out where can I do that? I am having CLkOUT as 1Vp-p. I want to program to 2.5 Vp-p.

Re: How to configure the amplitude on the CLK OUT coming from NI PXI-6652?

Hi Solanki-

 

     The CLKOUT signal's amplitude is software-selectable between two levels.  Under a 50 Ohm load, you can change the amplitude from 1 V p-p to 2.5 V p-p by using an niSync property node.  This can be found in LabVIEW under the NI-SYNC palette.  Place the property node down and click on the word "Property".  Select Clk Properties»Clk Out Gain Enable.  Then right-click on the property node and select "Change All to Write."  Then right-click on the input to the property and select Create»Constant.  Change the constant to True and your CLKOUT will now be high.

 

     I hope this helps.  Best of luck with your application!

Hi Gary,
   Thankyou very much that works. I had that CLK out enable gain in my VI but in order to see the Amplitude change, before running the VI I need to Set the value True and than run the VI.
