I did not have a proper fine pitch GSG probe or anywhere to land it, so I created a crime against metrology consisting of a pair of SMA cables off the front of the VNA, a pair of SMA to dual 0.1” pin header adapterss (yes, these exist), a pair of single ended 0.1” extension wires, and a set of PCBite SP10 probes. It wasn’t the slightest bit impedance matched and I had no way to calibrate it (as a rough baseline, insertion loss was somewhere in the vicinity of -10 dB with the probes touching due to all of the reflections in the setup) but for narrowband measurements where I just wanted to check if the crystal was resonant or not, it would do.
