How would I go about doing that? For context, the ac mains signal is stepped down to about 300mv. I'm trying to use the ad2 waveform generator to supply a signal of the same amplitude at the same frequency in sync with the stepped down mains ac signal.

Hello, Is it possible to sync the waveform generator to a mains ac voltage source. I'm trying to put two signals into a comparator to generate two squarewaves for phase angle measurement. One signal is from the mains ac source, the other from the ad2 waveform generator. When i do this i get drift on the ad2 waveform. Is there a way to sync them together? The ad2 is set to 50Hz (UK) but it doesn't stay in sync. Thanks D
