TEST CONFIGURATIONS Input Reflected-Ripple Current Test Setup Input reflected-ripple current is measured with an inductor Lin and Capacitor Cin to simulate source impedance. DC Cin Lin DC Load Oscilloscope Current Probe Lin(4.7 µH) Cin(220 µF, ESR < 1.0Ω at 100 KHz) DESIGN REFERENCE Ground Loop Problem In Signal Transmission And Ground Electric Potential Difference There are many reasons causing ground loop problem in instrument circuit.When the signal transmission and receiving devices connected toa different location or of different power supplies, it will lead to ground loop, and it is common in long cable transmission. Most of the reason is that the equipment of the metal shell had physical contact with the ground. Ground loop produces electric circuit, and form error sources. Because the accuracy of the signal can not be measured through simple observation in the receiving end of the signal. the land circulation for different ground potential will bring error that can't be detected to signal loop. There is also a signal error problem caused by ground loop in the absence of two-wire signal isolation transmission. Signals like lightning signal and surge signal will load on the signal line along with long wire, and damage modulation and detection devices on the port. In another case, two components of the different potential port may lead to the port voltage exceeding, and damage the device port subsequently.
