Software cuts test time for mobile phones
Apr 20, 2006 11:05 AM 

Agilent Technologies announced the release of its Fast Device Tune Measurement, a calibration solution that reduces manufacturing calibration test times. This solution is suitable for wireless device manufacturers and reference design houses that calibrate wireless devices.

Fast calibration techniques, such as 8960 Fast Device Tune, can provide an order of magnitude reduction in test time, reducing calibration time for a typical GSM phone from approximately 60 s to just 1 s to 2 s.

The Agilent E1999A-201 Fast Device Tune Measurement allows a user to simultaneously calibrate a mobile device transmitter's output power level and receiver input level across level and frequency in a single frequency band sweep. When the device is operating in a user-controlled test mode, it is forced to transmit a predefined series of power steps at various uplink frequencies. Simultaneously, the receiver is tuned to perform measurements of the test set's signal, such as RSSI, at various downlink frequencies and power levels.

Fast Device Tune Measurement addresses GSM/GPRS, EGPRS, W-CDMA and cdma2000 technologies. Fast Device Tune W-CDMA and cdma2000 solutions are based on a 20 ms step size, while the GSM/GPRS and EGPRS solutions are based on the GSM timeslot and frame structure.
