Engineers connect a VNA to a circuit board for low-impedance measurements using a variety of methods.

These methods primarily include connectors, probes, and soldered pigtails. Each of these methods has advantages and disadvantages, and no one solution is best in all cases. In this session both qualitative and quantitative assessments are presented for each method, highlighting the limitations, and providing tips to optimize the measurement accuracy. In addition to connectivity on the probe side of the measurement, the PCB side is also considered and several options for connectivity are presented.
