Thank you for your help!! On a side note, you didn’t see all my video, possibly, because I started the generator alone too… but no worries.
Your question made me realize a crucial error - a simple one. It’s “working” now for two reasons - working in quotes because I still need to see more of PCGU1000 is doing, with more options. More on that later.
First, I purchased a new USB cable and it’s connecting with that - no errors now.
Second, you mentioned that I tried to start a device that I don’t own - the PCSU1000.
So this brings up my follow up question. I need a digital oscilloscope with controls and readout - this is why I thought I need to click on the other button. What options do I have? I know the generator can do more than the ‘small box’ reveals. In other words, when I start the PCGU1000, it says I can run it in demo mode, and this brings up the oscilliscope, not the function generator. This tells me that I should be able to use the oscilloscope gui. In fact, when I click OK with only the PCGU1000 button clicked, it briefly brings up the oscilliscope for a second and then it goes away before the small generator window opens (to stay).
Also, to a separate question, can I use a software that will give me an oscilloscope readout with more controls? Thank you.
