alignment.
Ensure all cables and wires are repositioned correctly.
● Never test a mobile phone WCDMA transmitter with full TX power, if there is no possibility to perform
the measurements in a good performance RF-shielded room. Even low power WCDMA transmitters
may disturb nearby WCDMA networks and cause problems to 3G cellular phone communication in a
wide area.
