The CA 9260 artificial antenna network (AAN), as described in CISPR 25 Annex B (150 kHz to 6.2 MHz), is used to measure the S21 of the Impedance Converter VHIC 9260.
The EuT side of the CA 9260 must be connected to the input of the VHIC 9260 without a cable.
The Calibration Fixture features a BNC-female connector at the input and a BNC-male connector at the output (EuT). Detailed instructions on using the calibration fixture are provided in CISPR 25 or EN 55025, specifically in Annex B.
