Which types of test-levels are supported in an Multiband Immunity test?

In a multiband radiated immunity test, the following test-level types are supported:

• Power closed loop method: The generated power is regulated to be at least the specified power value, where the power is based on the measurement of the forward-, reflected- or signal-power.
• Measured power limit: The generated power is limited to specified power value, where the power is based on the measurement of the forward-, reflected- or signal-power.
• Electrical field closed loop method: The generated electrical field is regulated to be at least the specified electrical field value, based on the measurement of one or more electrical field probes.
• Measured electrical field limit: The generated electrical field is limited to the specified electrical field, based on the measurement of one or more eletrical field probes.
• Electrical Field substitution method: The generated electrical field is regulated to be at least the specified electrical field value, based on the electrical field calibration file, and the specified forward-, net- or signal-power measurement.
• Calculated Electrical Field limit: The generated electrical field is limited to the specified electrical field, based on the electrical field calibration file, and the specified forward-, net- or signal-power measurement.
• Measured current limit: The generated current is limited to the specified current, based on the measurement of the current.
• Measured voltage limit: The generated voltage is limited to the specified voltage, based on the measurement of the voltage.
• Magnetic Field closed loop method: The generated magnetic field is regulated to be at least the specified magnetic field value, based on the measurement of the magnetic field.
• Magnetic Field limit: The generated magnetic field is limited to the specified magnetic field, based on the measurement of the magnetic field.
• Magnetic Field substitution method: The generated magnetic field is regulated to be at least the specified magnetic field value, based on the magnetic field calibration file, and the specified forward-, net- or signal-power measurement.
• Calculated Magnetic field limit: The generated magnetic field is limited to the specified magnetic field, based on the magnetic field calibration file, and the specified forward-, net- or signal-power measurement.
• Minimum performance: The generated power is limited based on the influence of the EUT, that is based on the measurement of the AD-convertor

• Minimum performance: The generated power is limited based on the influence of the EUT, that is based on the measurement of the AD-convertor

A multiband immunity test will always try to regulate to a power value where all the specified test-levels are achieved. However, once a measurement value reaches one of the specified limitations, the regulation will be stopped. The final regulated power tries to be at least above all the specified test-levels, but it will never be higher than a specified limit.
