[SOLVED] Need help deciding between SDS804X HD and SDS814x HD osilloscope.
(1/3) > >>

Hi, I'm mainly a software engineer and a newbie to electronics.
I'm looking to buy an oscilloscope for embed dev + designing circuits like scales/sensors. Right now I'm designing something with the AD7190. I also want to use it to analyze my power supply designs (DC-DC and low wattage usually).
I was going to buy the SDS814X but a friend of mine told me I could just easily hack the SDS804x HD to 200mhz with a keygen. As a newbie, I'm not even fully sure how these things work so I'm getting a second opinion, especially as the 814x costs a ton of money!
the SDS804x HD is 150CADcheaper   (that's a nice hot air I also need!)  and even if I fail to use keygen, surely 70mhz is enough for my use case still right? my worry is that even if I do make the keygen work the circuit or the calibration is different on the units.

- Thanks  :)

Welcome to the forum Amelia.

SDS800X HD models also offer a Power Analysis option, perfect for detailed analysis of switching supplies where you are unlikely to ever challenge the stated 70 MHz BW of the 804 model.

All/any option provides for 30 free trial uses before permanent licensing is required.
I have heard whispers 804's actual -3dB BW is closer to 115 MHz and I have tested my 814 to ~155 MHz so a 804 will serve you well and there's probably no need you'll ever require a higher BW model.

Thank you for saving me 150CAD :P

Do you know anything about the possible hacks either?
I'm going to place my pre-order :) Very excited... this is my first oscilloscope and I dreamt of buying one since I was a kid!

Please read the corresponding SDS 800X HD thread, where your initial question would also have fitted.

I did! However, the hacks are on early models and not the release ones.
There's a very small chance they sent the same hardware for the testing but changed them for the release or something?
