Hi,
I use this Hameg feature since 1981. The construction is rather easy, you need an independent winding on the 50(60) Hz power transformer and 2 resistors. One resistor will exhibit voltage and the other will exhibit current. This way, you will obtain a U-I-diagram with 7V RMS and 10 mA RMS. I have measured tunnel diodes this way without destroying them. B&K was a trade name for some scopes in the US.

Some inexpensive oscilloscopes (B&K? Hameg?) have this capability built in.
