The low frequency range of the E9304A 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 E9304A 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.

C A U T I O N

The E9304A sensor is DC coupled. DC voltages in excess of the

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