A method (200) of over-the-air testing of a transmission equipment (20). The method comprises transmitting (202) a transmission signal from the transmission equipment. The transmission signal as transmitted comprises emissions in an in-band domain (102) and emissions in an unwanted domain (110). The method comprises arranging a frequency selective surface (40) to receive the transmission signal. The frequency selective surface (40) attenuates the transmission signal in the in-band domain (102) of the transmission signal. The frequency selective surface (40) allows propagation of the transmission signal in the unwanted domain (110) of the transmission signal. The method further comprises measuring (206) in a measuring equipment (25) a parameter of the transmission signal in the unwanted domain. The frequency selective surface (40) is arranged between the transmission equipment (20) and the measuring equipment (25).
A method of over-the-air testing of a transmission equipment, the method comprising:
A test system configured to test a transmission equipment to be tested in an over-the-air test, wherein the transmission equipment is configured to transmit a transmission signal, and the transmission signal as transmitted comprises emissions in an in-band domain and emissions in an unwanted domain, the test system comprising:
