Electromagnetic Compatibility (EMC) Measurements
The low frequency range of the Keysight 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 Keysight 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.
TheKeysight 9304A sensor is DC coupled. DC voltages in excess of the maximum
value (5 Vdc) can damage the sensing diode.
