Illustrative model of a TESTUPS 3 m semi-anechoic chamber per CISPR 16-1-4 — ferrite tile lining (100 × 100 × 5.2 mm, centre-screwed to the RF shielding panels) beneath pyramidal absorbers, six honeycomb waveguide air vents for EMI-tight ventilation, four low-EMI LED luminaires immune to 200 V/m, a 1.2 × 2.5 m semi-automatic RF-shielded swing door with pushbutton and manual arm, conductive ground plane, flush-mounted Ø 1.5 m turntable (285 mm centre supply opening with AC / DC sockets), 80 cm non-conductive wooden test table with a Ø 10 cm cable hole, 1–4 m fiberglass tilt antenna mast, and a 3 × 4 × 3 m RF-shielded control room on the mast-side wall — minimising RF cable loss to the EMI receiver — housing the control PC, EMC test software and positioning controller. The sweep shown is stylised, not measurement data.
