So I ended up finding a steal of a deal on eBay (uh oh... here we go.) It's an old HP Agilent 54503A 500MHz Digitizing Oscilloscope. I managed to snag it at a cost I could manage, and figured since it's a 500MHz scope, it'd be a beauty to have on the bench.
The seller listed it as in working condition.
Well after waiting a few weeks for it to get here, I finally got it today, and powered her up. Everything appeared to be fine... So then I decided to test it and put it to work on a PWM circuit. Nothing. Not even a flinch on the screen.. wary, I ended up running a self test:
So it failed some pretty important stuff. I'd imagine the D/A and A/D Converter is kinda important, as well as the NVRAM and Analogue Trigger.
So I'm assuming that is why I can't use the dang thing.
So I figured maybe, it just needs to recal, so I dipped into the menu and boom:
So wondering if it was an easy fix, I gave Agilent a call. They told me that the Cal Ram can be typically write protected through a switch, which may be inside or on the back of the scope. I don't have anything on the back of the scope, so I figure I'm going to have to pop the cover.
Here's the problem. I'm not going to open it, unless I know it can be fixed. I'm thinking I'm just going to send it back to the seller... It is DOA and not in working condition. The device powers up but is a useless paperweight to me in this condition...
Anyone care to enlighten me or lead me towards a possible solution. I really don't want to send it back if it can be repaired..
If I need to pop a few easy to get to IC's I figure I'll keep it. But if it's a PITA or too much work, she's going back. I could use that money on something else.
