When building calibration standards and kits, we were actively seeking test cases that would validate (or invalidate) the accuracy of the methods we develop. A straightforward test is measurement of an open-ended pigtail after calibration.

Dicaliant stands for Diagnosis and Calibration of Antenna Measurements. It was established to tackle the confusions around measuring antenna impedance, which is an enduring topic, despite automated instruments existing for decades.

Phase-accurate on-board S-parameter measurements using pigtails up to 8.5 GHz
