Hmmm... to get rid of the measuring tip, okay... but you should add the termination and make the correct compensation. If I have missed this, I'm sorry. But just a coax cable is not all to get a reliable, high quality measurement.
IMHO you should get yourself a crash course in measurement principles & techniques. What's the big idea using terminated coax cable measuring DC voltages - I don't get it ? it does not in any case improve measurement accuracy at all. Your measurement point is already a VERY low resistance because it is a power supply. Instead you should use a better quality probe and then calibrate your oscilloscope readout using that probe. Also have a look on your oscilloscope generic readout accuracy - you may be surprised how bad it really is. Good luck and all the best ☺
there is not much to get - you got it in the first sentence. lad has absolutely no idea what he is doing and will soon fry his toy (ds1k series are 1m input with 0.01-1000x attenuation^^)
my progress with the cheapaschips challenge, just sent 12v to core yaaay. im still using the evc and multimeters fo measurment. but I might try this out for my work scope
It looks like RG-58 cable. To reduce interference you could try some less common coaxial cables with more shielding.

Cool
Ill try to replicate
I been meaning to make a digikey order, just trying to find enough stuff i want to qualify for the free shipping lol

What are you measureing it for?
im firsttttt
