Electromagnetic Compatibility (EMC) Measurements
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.
The E9304A sensor is DC coupled. DC voltages in excess of the maximum value (5 VDC)
can damage the sensing diode.
