I just recently received my Picoscope, it is a 4425A with the new bnc + leads. I like them for the amp clamps and cop probes but was wondering why the regular test leads use them. Is their some advantage to them over the older bnc type leads?

I own a 4425 not a 4425A, so I am not the best person to ask.  Using a 4425A, if you had been capturing amperage with or without a BNC+ type current probe, then you unplug it because you want to measure voltage with a 1:1 BNC+ lead, the software will automatically change probe type to reflect the change.  You'll just have to set the voltage range if applicable and proceed.  On a 4425, you'd have to select the probe type because the software would still show that channel with your previous amperage settings.

Hi Dave,

Congrats on the 4425A. 

I second Grant's feedback.  My understanding is the 1:1 leads operate the same for BNC and BNC +. 

For my day-to-day use, the beauty of BNC+ lies in the  expansion of the scope's functionality and ease of usage: status LED's, use of Pico resistance leads & Pico temperature probe, automatic probe detection, and the items you mention- COP probe and no more batteries for the scope powered amp clamps (my personal favorite).

There likely are other advantages as well, I have seen similar BNC+ -ish style designs on scopes for laboratory use on youtube (not necessarily geared toward automotive far as I can tell), but further info on a non-automotive laboratory based scope is beyond my knowledge. . . .

I am curious to see what some other responses are. Hope my feedback helps.

Best,
Sam

The basic 1x voltage test leads use the BNC+ purely for lead identification and auto ranging. Its all about making the software do the thinking for the user.

Revealing my age here but I sincerely hope that he software DOES NOT make the thinking for the user..... :D

Auto lead detection was the only thing i could think of, I just wanted to make sure there wasn't some other feature that i didn't know about.

Not revealing your age, however thankfully revealing you have a brain and freedom of your own thoughts!

BRAVO BRAVO
