Because the WCDMA network disturbs the RX side testing of the WCDMA
phone and the Tx signal of the WCDMA phone can severely disturb the
WCDMA network, a shield box is needed in all testing, tuning and fault
finding which requires WCDMA RF signal.
The shield box is not an active device, it contains only passive filtering
components for RF attenuation.
