8.2.2 Automatic Calibration Procedure
This procedure requires the use of a Gigatronics 8541C power meter.
NOTE: To ensure that the telephone operates within set SAR margins, Panasonic recommends that a power meter
capable of measurement to an accuracy of ?0.2dB is used when calibrating power levels. Use of a less
accurate power meter may result in the telephone failing to meet SAR standards.
1. Connect the test equipment as shown in Figure 6.5:
2. Select GD87 and then select the required band, e.g. ?GSM (900 MHz)?.
3. With the CB2000 software running, select ?TX CAL? button
4. When the Tx Calibration screen is displayed, start automatic calibration by selecting the ?Run Auto Cal? button.
5. Once the automatic calibration has finished, select the ?Run Auto Verify? button to verify the calibration.
6. When finished, select the ?EXIT? button to save data to the handset. A confirmation message will be displayed in the next
