Frequency Response Below 300 kHz Performance Test

Frequency response (aka. Flatness) is defined as the amplitude deviation from the reference amplitude at 50 MHz. The complete EMI receiver frequency response is measured with several tests. The model and options of the DUT will determine which tests are run from the list below:

• Frequency Response Above 3.6 GHz (Preamp On)

• Frequency Response Above 3.6 GHz (Preamp Off)

• Frequency Response 50 MHz to 3.6 GHz

• Frequency Response 9 kHz to 50 MHz

• Frequency Response Below 300 kHz

Band 0 frequency response is specified relative to 50 MHz. This test measures frequency response (flatness) over the frequency range from 20 Hz to 300 kHz for MXE, and 3 Hz to 300 kHz for PXE, relative to the response at 300 kHz. This is converted to a frequency response relative to 50 MHz by adding the normalized (to 50 MHz) 300 kHz frequency response from the 50 MHz to 3.6 GHz Frequency Response Test.
