Hi,
In the next few days I´ll send the probe back, I ´ve made some other measures, they looked ok.
So my verdict:
+Form factor, small builded
+Building quality
+High bandwith
+Degaussing function
+relative low noise
-Measure resolution
-Bandwith linearity
-Price
In my opinion, the last point is the most important.
Even back then I didn't understand why the version with the normal BNC connection costs twice as much.
The current clamp themselves are the same.
So I would say that if the CP1003B cost exactly the same as the non-B version, it would be a good current clamp for the money (if you ignore the non-linearity).
As it is, however, it is definitely overpriced and what is also a pity is its measurement resolution, which only provides usable results from 20mA/div.
Once again, the old Tektronix A6302/AM503 combination has shown that it can't be beaten.
I am still waiting for an affordable alternative, unfortunately the Micsig is not it.
