Hi Afonso,<br> <br> I agree with you that the problem is mostly with my Siglent. I'm trying to find other way to generate four signals in a sequence. Thanks for all of your help!

Hi Afonso,<br> <br> Thank you for the reply. During my testing, if I keep the two function generators outputs on, then the trigger delay is stable. But If I turn any output off then back to on, then the trigger delay shift. Please see the attachment, which is the signals I want. Thanks.

Hi Afonso,<br> <br> Yes, I connected the master device's trigger out to slave device's trigger in, and connected the master's EXT REF OUT to the slave's EXT REF IN. I did get four channels' signals on a Oscilloscope. My problem is the phase shift&#160; between the signals from two devices kept changing every time I tuned any channel output off then back on. Because I only have one AFG, I used another function generator from Siglent, SDG 1032X. I think there should a place to let me set the delay between the master and the slave. Is there a way to keep the delay between two devices stable?&#160;

<br> <br> I want to generate four pulses with each one delaying 1 us from its previous one. I have one Tektronix AFG 31000 and two Siglent SDG 1032X. At first, I tried to synchronize two SDG 1032X, but there was a problem that the phase shift was not fixed between two devices when I turned the output off and on. I called Siglent for support, and they said the SDG 1000 series were not good at sync up two devices. Later, I tried to synchronize AFG 31000 with one SDG 1032X. Still, there was the phase shifting problem. Does anyone know where to set a fix delay between the master device and the slave device? Thank you.<br> &#160;

Hi Afonso,<br> <br> Thanks for your help. It works.

I need to inject a single pulse to my circuit, but my AFG31000 always output a pulse train. Can someone tell me how to do it? Thanks.
