Using U2000 Series USB Power Sensors
Electromagnetic Compatibility (EMC) Measurements
The low frequency range of the U2004A make it the ideal choice for making EMC
measurements to CISPR (Comite International Special Perturbations
Radioelectriques) requirements, and electromagnetic interference (EMI) test
applications such as the radiated immunity test (IEC61000-4-3).
DC coupling of the U2004A input allows excellent low frequency coverage.
However, the presence of any dc voltages mixed with the signal has an adverse
effect on the accuracy of the power measurement.
The U2004A sensor is DC coupled. DC voltages in excess of the maximum
CAUTION
value (5 VDC) can damage the sensing diode.
