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?
