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.
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!
