content: I want to replace my scope probe. But I have no knowledge to choose a new one.Can anyone give me some reading that would help me doing a more informed decision on which one to choose? In terms of resistance, capacitance, attenuation...My original one was Leader LP-16BXDigging into this website bellow I could roughly find some specshttps://probemaster.com/scope-probe-to-scope-probe/Oscilloscope Probe 40 MHz X1/X10 600V 59 inch

content: There are many different classes of probe, for different purposes,with different advantages and disadvantages.Seehttps://entertaininghacks.wordpress.com/library-2/scope-probe-reference-material/and you will be in a better position to give us the nformation necessary for us to advise you.

content: Well, I bought a new scope in 1986, and it came with some Probe Master probes, I think. They lasted about 2 WEEKS. I got some cast-off Tektronix probes from work, and they are STILL working! Ummm, that's over 800 times longer life. (I did have the hair-thin wire in one of them break, but I was able to fix it.)Just get a generic 10X probe, and it should have enough compensation adjustment range to cover most scope's input attenuator. If you want to be sure, look up the input capacitance of your specific scope and check that the intended probes cover that. All scopes should have a 1 Meg Ohm input impedance.Jon

content: What oscilloscope make and model and bandwidth are we discussing?Acceptable 100MHz x1/x10 probes can be had for $10 each and good higher bandwidth x10 probes can be had for $40.

content: Quote from: TimNJ on January 16, 2019, 03:35:51 pmI had been eyeing those as potential upgrades from the rather barebones probes that came with my Rigol. How soft is the wire? Are the accessories good?

content: Quote from: tooki on January 17, 2019, 02:35:34 pmThe wire is great. Very soft silicone. The probe is a bit large, compared to some other probes, like from Tektronix. As far as accessories...umm I think it comes with a ground spring tip adapter? Other than that, what else do you want?
