Auto tuning

This phone can be tuned automatically.

Autotune is designed to align the phone's RF part easier and faster. It performs calibrations, tunings and

measurements of RX and TX. The results are displayed and logged in a result file, if initiated.

Hardware set up

Hardware requirements for auto tuning:

• PC (Windows 2000/NT) with GPIB card

• Power supply

• Product specific module jig

• Cables: 3 (alt.1) RF cable, 1 GPIB cable and DAU-9S

• Signal analyser (TX), signal generator (RX) and RF-splitter or one device including all.

prototype filter. For this reason, the calibration is done only once, not separately for 3 bands.

This tuning doesn’t require RF input from an external signal generator.
