Reviewed in the United States on April 7, 2024
I'll admit I'm a Siglent fan. I also have a Siglent scope, an SSA 3012X spectrum analyzer, and a SDG 1032X signal generator. The only problem I've ever had was with the SDG 1032X, and it was my own fault. Customer service was outstanding. They fixed it promptly under warranty and were extremely pleasant to deal with.As for this SDG 2122X, I put it through its paces immediately when I got it. I checked the THD on its sine waveforms, and they were excellent. I checked modulated waveforms, etc. Everything worked perfectly as expected. Once you get used to the GUI, it's very intuitive. My only caution is to pay attention to loads and any voltages applied to the outputs. I often apply a cap as a DC blocker. Stay within specs, and these things are rock solid.My suggestions to Siglent are (1) to make the SAs and scopes stackable like the SGs; and (2) settle on one GUI and file management protocol and apply it to all your devices. (I know you've considered it; consider it again.)It goes without saying that Siglents are priced right. If I need a piece of electronic test equipment and Siglent happens to make it, I'll buy Siglent.
