## Description

*Probes and other equipment attached to the fixtures in the product pictures are not included.*

##### What is it?
There are three variants of this fixture (see pictures):
* single ended
* common mode
* differential
* you can also get all three in a discounted set!

These fixtures allow you to connect a device under test (like the awesome probe prototype you just designed and want to characterize) to a signal generator, scope, VNA or something else via two SMA connectors (or four SMAs for the differential version). You can even screw the whole thing down.

##### Features
- Mounting holes on all variants: M3, on a 30 mm x 30 mm square
- 50 Ohm coplanar waveguides with ground plane
- 1.6 mm thick
- ENIG finish

The common mode and differential variants have symmetric geometry.

##### Why
I created these to characterize my own probe designs - in single ended, differential and common mode setups. I offer them so that you don't have to make them. Really, it's not that special, but saves time.

##### Customizations are absolutely doable, if you need something different - just ask!
