  • Page 52 TEST AND MEASUREMENT On the spectrum analyser measure the carrier leakage ratio. Carrier leakage ratio is measured as the ratio of peak power and the power at 68 kHz below peak frequency. Example: peak power (902.468 MHz) = 33 dBm power at 135 kHz below peak power = -9 dBm carrier leakage ratio = 33 dBm - (-9 dBm) = 42 dBm Figure 6.26: Carrier leakage ratio...

If the new carrier leakage ratio is greater than 30dBc then the unit is OK (offset calibration is complete). If the original carrier leakage ration (see I,Q OFFSETS step 2) is greater than the new carrier leakage ratio go to I Dec Calibration.
  • Page 55 TEST AND MEASUREMENT If the carrier leakage ratio is greater than 35 dBc then unit is OK. (offset calibration is complete). If not then repeat steps 1, 2 and 3 above for Qch offset values: 87, 67, 47, 27, 7. If the carrier leakage ratio is still less than 35 dBc then unit is a fail.
  • Page 56 TEST AND MEASUREMENT IQch Gain Calibration Set IQch gain to -0.25 dB. a. On the Channel box press F6, and select TRIM OTHER. b. Press move left arrow until IQCH GAIN field is highlighted. Press ENTER. c. Enter 1 (for -0.25 dB) into the data field. Press ENTER. Measure the image leak ratio.
  • Page 57 TEST AND MEASUREMENT 6.5.6 Battery Charging & Calibration There are three procedures to calibrating the battery, voltage, temperature and charging calibration. A Battery Calibration Voltage Control Unit (BCVCU) is used to provide the necessary voltage levels for these checks. The BCVCU replaces the two regulated power supplies and 82 Ohm resistor required to calibrate previous mobile phone products.
  • Page 58 TEST AND MEASUREMENT Charging Calibration NOTE: The charging calibration procedure requires an interface cable (part number JT00004), modified as shown in the diagram below, to allow EXT_PWR to be fed via pin 9 of the D-TYpe connector to the phone connector. Figure 6.33: Modification to Interface Cable JT00004 Ensure that the BCVCU output is set to 4.1 V output and the MODE or EXT_PWR switch set to ON.
