Hey guys, I am new to these forums. Forgive me if i am a bit rusty on some things. I have basic EE knowledge, and i want to try something.
I have PC motherboards laying around, and well I overclock systems for personal use. What makes a motherboard good for overclocking is how well its power supply is, usually a 12v in and 1-2v out PSU fed by the main AC/DC PSU, which needs to deal with load transients of 100A steps. Sometimes max current pull might be over 200. of course these power supplies are actually built to supply a lot more than that, but how well their output voltage is regulated can tell a lot about how well they are doing. Switching frequency is going to be from 250khz to 1mhz max.
Until now I didn't have a scope at my house to do this testing, i just used them in labs. I have one now, and i want to measure, Peak to peak (ripple), overshoot, undershoot, and whatever else you guys think this basic scope can measure. It only cost me 200 but I read a lot of good reviews about it, its a DSO 2090.
Anyways I have 1x/10x probes, and I was going to use a coaxial cable that is shielded soldered to MLCC caps on the underside of the CPU socket. This is how we measure the voltages with a multimeter.
Anyways i was wondering if i need to compensate the probe or if it shouldn't matter?
Any tips to get the best readings?
