RF Troubleshooting and Manual Tuning Guide
3. Connect an RF cable between the RF connector of the product-specific module test jig and measurement
equipment or alternatively use a 50 ohms (at least 2 W) dummy load in the module test jig RF connector,
otherwise GSM or WCDMA PA may be damaged.
Note:
There are three antenna connectors in the module jig:
• one for GSM
• one for WCDMA
• one for Bluetooth
Make sure that all connections are made to the correct RF connector.
Normally a spectrum analyser is used as measurement equipment.
Note:
The maximum input power of a spectrum analyser is +30 dBm.
To prevent any damage, it is recommended to use 10 dB attenuator on the spectrum analyzer input.
4. Set Tx on.
