What is the best PCB socket for oscilloscope

[crgarcia]

Hi,

I built my first PCB (hobbyist only), and I added some 2.54mm sockets, that I often use for probing with the oscilloscope.

The problem I have is that I don't want to be holding the probe, so I usually add some wires and use the GND clip, but this creates large ground loops and add a lot of noise into the scope, which for some measurements is a problem.

What other alternative footprints/sockets/... can I use to make it easy to hook the scope, reducing ground loop/noise?

Thanks!

BNC connector, 1m Zin use Tektronix 10x probes

How fancy do you want to go? Lecroy:
PK1-5MM-107
or
PK1-5MM-112

Beyond that you can do 50ohm direct with an appropriately terminated BNC/SMA/MHF/U.FL
