As I told you, Hameg after-sales is very helpful and very nice.
They still have all the spare parts.
For this reason, it is often better to buy a HAMEG used cro than an used cro of another brand.
I have worked with a HM1507 for testing and maintenance of no breaks.
I was not satisfied with it because it often crashed in digital mode when doing a load transfer Inverter / mains.
I have an HM1505.
It looks like the HM1507 but analog only. (150 Mhz).
But I prefer the older HAMEG cro's.
The hm605 is very good, maybe the best.
The HM1005 is also very good, but it has no component tester, which is a serious shortcoming.
In my opinion, it would be the best if he had a component tester.
And now, enjoy your HM1507....
NB: The BAQ34 could be replaced by a LL4148 without any problem.
