content: I don't use my Function generator often, usually just to inject clock signals mostly or other very simple wave forms.I have been trying to replicate the video below using EasyWaveX to generate a Crank (Inductive) and Cam Sensor (Square) with EasyWaveX on the SDG2122X.Anyone that's an expert lend a hand provide good clear instructions?Thanks.

content: If no one responds, I'll try and set up their latest version of software in the next day or two and see if I can sort it out.I watched a few of this channel's videos on automotive. I do something similar to what they show using a custom board inside the PC and a bit of external hardware to simulate the loads and what not for the engine controller (ECM). Basically, I simulate a motorcycle in software using the stock ECM and gauge cluster.What are you attempting to do?

content: I downloaded their software and took a quick look. It appears you would make two separate files, one for each channel. Of course you will need to know the details about your particular engine/transmission combination. Have you made any progress? What part are you stuck on?

content: I just started using it without reading the document. Made two waveforms. Hall effect -1 tooth for the index. Also some sort of VR. Seems easy enough. You can also import CSV files if you have other software to create the waveforms. Software could use a few features but certainly usable.Still weighing the the good vs bad experiences. The more I use Siglent's products, the less hesitant I am about buying them for home use. Maybe....
