Square Wave Generator ( FPGA )

Hello.

I'm using the NI FlexRio PXIe 7962R.I should generate a square wave output from fpga.I created  an adapter module socket. I created the socket clips and everything is working. I used the Square Wave Generator in the single-cycle while loop. However, sending him running and testing the output signal with the oscilloscope , I see that a square wave is generated non-regular. Below the 2.857 MHz the displayed frequency oscilloscope is regular, but by settting a frequency above the frequency that 2 MHz visualize the oscilloscope is always 2.857 MHZ and in addition a signal gitter lot.

As parameters in the square wave generator I used:

Output:Boolean

Fpga clock Rate: 64 MHz

Execution Mode: Inside single-cycle timed loop

 

How can I resolve it?

Place the image of my vi.

 

Thanks.

Hello Brugiando,

 

I am afraid I did non understand the issue that you are facing.

When the frequency of your signal is more than 2.8MHz you can not see it properly in the oscilloscope?
