Features Helps locate and identify potential interference sources in the building blocks of electronic components. In combination with low-noise preamps, frequency, phase noise and spectrum components can be measured. Accurate manufacturing ensures stable performance and reliable use. This probe kit is a new and updated version that has been improved and optimised based on the old generation products, with greater bandwidth and ergonomic design. The PCB uses a 1.6mm thick double-sided board and the whole process of spraying tin to ensure good passage performance of large and small currents.
