Re: 7K series - Conceptual question - What's the 3rd most useful plugin


Hi Fabio-

I would definitely recommend a 7A13. I keep a pair of those in the 7623A that's on my bench and I find them extremely useful and versatile. The later ones have a digital display of the offset voltage. When you need DC coupling AND the ability to see a very small signal riding on top of a large DC voltage, the 7A13 really shines. For checking ripple/stability of a power supply rail, as well.
