I attach a psdatafile showing the jitter on a 100kHz square wave out of the AWG which seems excessive to me. It is much better for a sine wave and also for lower frequencies. This is not a problem for me and I post it here to bring it to your attention.

The update rate of the signal generator is 1.548 MHz which corresponds exactly to the jitter you see.

With a square wave you are going from a high value to a low value in 1 sample so a 1 sample jitter on the edge would be expected.

Got it, thanks Martyn.
