Hi everyone, Just a reminder that the SCV IEEE EMC Society Meeting will be held 8 December - dinner and technical presentation both at Auspex. Menu choices will include prime rib dinner, vegetarian tortellini, and some traditional holiday dishes. The Product Safety Society will be meeting jointly with the EMC Society.
December 8, 1998 Where ----- Dinner 5:30 - 7:30 PM Auspex Cafeteria, 2300 Central Expressway, Santa Clara Technical Presentation 7:30 - 9:30 PM Auspex, 2300 Central Expressway, Building A, Santa Clara, CA Speaker/Topic ------------- Neven Pischl, Bay Networks, "A New Common-Mode Voltage Probe for Predicting EMI from Unshielded Differential-Pair Cables" Details ------- On December 8, the Santa Clara Valley Chapter of the IEEE EMC Society will hear a presentation by Neven Pischl of Bay Networks on "A New Common-Mode Voltage Probe for Predicting EMI from Unshielded Differential-Pair Cables". Common-mode (CM) currents on I/O cables are primary sources of EMI in many electronic devices. Measuring the CM voltage at the I/O connectors can be an alternative to measuring CM currents. Sources of CM currents and voltages are discussed, and a CM voltage probe for prediction of the EMI levels from unshielded differential twisted-pair cables is described. CM voltages at the RJ-45 ports were measured and correlated to the 10m E-field levels of 8 DUTs. A CM-voltage level that corresponds to the EN 55022 A limit has been derived. This allows the prediction of radiated emissions based on CM voltage measurements at the connectors. This bench-tool can be instrumental in reducing the time and cost of troubleshooting EMI problems. --------- This message is coming from the emc-pstc discussion list.
