The GND 25 ground plane ensures the RF-compatible contacting of the probe during an EMC measurement at a test IC. The GND 25 consists of steel with a gold plated surface. The recess (103 mm x 103 mm) is designed for the placement of GNDA ground adapters (GNDA 01-04) and TEM cell prints (100 mm x 100 mm).
The CB 0708 connection board is placed into the undersite of the ground plane. On the ground plane there are three openings for LEDs.
