Two dual ground spring needles for the PCBite SQG60 probe, in both AC and DC versions. The ground part is 5 mm (0.20 in) in diameter and places two spring-loaded ground needles on either side of the signal needle, 3 mm (0.12 in) from the signal and 6 mm (0.24 in) apart.
The short, symmetrical ground return keeps the full 6 GHz bandwidth of the SQG60. The SQG60 has no single ground spring, so the dual spring-loaded ground needles are its ground connection for every measurement.
The spring-loaded needles give a consistent, low impedance ground contact without clips or soldering, whether the probe is used handsfree or handheld.
