In love with the EEVBlog Differential Probes

[forrestc]

Micro-review:

I bought a couple of the EEVblog differential probes.   Figured it would be nice to have a set of decent ones.   

My last experience with differential probes was less than positive.   Always replacing batteries.  Questionable accuracy.   Low bandwidth.   Odd artifacts.   I'm sure it's because I got something inexpensive from a questionable seller.   But when I bought them it was pretty much all that I could afford.   Definitely a waste of money in hindsight.

These are completely different.  I don't even notice that I have the differential probe in the circuit, well except for the fact I just gained differential measurements.   Accuracy is high enough that I can trust the amplitude of the signals on the scope.   And, the 70Mhz bandwidth is well above my needs.   I'm finding that having these has changed the way I approach troubleshooting/design validation in a very positive manner, since I am able to look at signals referenced to multiple points in the circuit.    I added 9VDC regulated supplies and no more battery issues.

I liked them so well, I bought two more.  I now have 4 of them, one for each channel on the scope.  I added some colored heat shrink to each connector and also at the cable entry into the electronics box to match the colors of each of the channels on the scope, so it is easy to tell which leads go with which channel.

About the only gripe is of course how much ANY differential probe costs.  But, it's hard to gripe about this seeing as how inexpensive these are when comparing specs to other similarly priced probes.

Headscratching whether to go the same way

or an isolated inputs 4 channel DSO with true isolation from power earth/ground    

Not cheap either way
