Master (Back?) the Basics: What is ESD?
by Anil Pandey, Principal R&D Engineer, Keysight Technologies and EDAboard.com forum member Electrostatic discharge(ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials caused by direct contact or induced by an electrostatic field. An Electrostatic Discharge (ESD) strike is a constant threat to device reliability and functionality. Many low-voltage core […]

A monopulse tracking system for satellite tracking
by Anil Pandey A tracking system in earth station antenna tracks the motion of the satellite. Especially in the case of Low-Earth-Orbit (LEO) satellites, that appears for the small time window to earth station antenna, it’s necessary to communicate with satellite effectively in that short duration of time and receive or download all necessary data, […]
