Electromagnetic Compatibility (EMC) Measurements

Electromagnetic Compatibility (EMC) Measurements

The low frequency range of the Agilent 9304A 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 Agilent 9304A input allows excellent low frequency coverage. However, the presence of any dc voltages mixed with the signal will have an adverse effect on the accuracy of the power measurement - see Figure 11 on Page 36.

Caution

The Agilent 9304A sensor is DC coupled. DC voltages in excess of the

 

maximum value (5 Vdc) can damage the sensing diode.
