PMM SHC-2/1000 Overview
According to the main EMC standards - CISPR, MIL-STD, IEEE/ANSI, etc. - the passive voltage probes are ancillary devices specifically designed to measure conducted disturbances when a LISN cannot be used, e.g. because the EUT requires currents exceeding the capabilities of available LISNs. As several generic and product standards may require the use of passive voltage probes, they are a must in a well equipped EMC lab and on the test bench of any design engineer. A passive probe connected to the RF input of an EMI receiver picks up the RF disturbance signal from the line under investigation. It also provides a standardized impedance and blocks the main AC/DC voltage, while signal attenuation protects the receiver front-end from saturation and damages. When operating the voltage probes, users must be sure to take all safety precautions relating to the AC or DC line voltages.
