Abstract

A calibration apparatus for calibrating a communications terminal comprises a data store arranged to store amplifier unspecific power control data, and a processing resource arranged to receive a first indication of a first desired output power level and a second indication of a second desired output power level. The processing resource retrieves from the data store a first amplifier unspecific value associated with the first desired output power level and a second amplifier unspecific value associated with the second desired output power level. An amplifier is operably coupled to the processing resource and arranged to generate a first output signal and a second output signal corresponding to the first and second retrieved values. The processing resource is arranged to receive a first measured value and a second measured value. Also, the processing resource is arranged to support an interpolator for performing an interpolation using the first and second measured values.

Claims (40)

a data store arranged to store amplifier unspecific power control data;

a processing resource arranged, when in use, to receive a first indication of a first desired output power level and a second indication of a second desired output power level, and to retrieve from the data store a first amplifier unspecific value associated with the first desired output power level and a second amplifier unspecific value associated with the second desired output power level; and

an amplifier operably coupled to the processing resource and arranged to generate, when in use, a first output signal and a second output signal corresponding to the first and second retrieved values, respectively;

wherein the processing resource is arranged to receive, when in use, a first measured value associated with the first output signal and a second measured value associated the second output signal, and the processing resource is arranged to support an interpolator capable of performing an interpolation using the first and second measured values.

2. An apparatus as claimed in claim 1 , wherein the processing resource is arranged to store the first measured value and the second measured value in the data store.

3. An apparatus as claimed in claim 1 , wherein the first indication of the first output power level is a first penultimate magnitude value at a first end of a range, and the second indication of the second output power level is a second penultimate magnitude value at a second end of a range, the range being an output power range.

4. An apparatus as claimed in claim 1 , wherein the first indication of the first output power level is a second smallest value stored in the data store.

5. An apparatus as claimed in claim 1 , wherein the second indication of the second output power level is a second largest value stored in the data store.

6. An apparatus as claimed in claim 1 , wherein the interpolation is a non-linear interpolation.

7. An apparatus as claimed in claim 6 , wherein the non-linear interpolation is a logarithmic interpolation.

8. An apparatus as claimed in claim 1 , wherein the amplifier unspecific power control data comprises a power level identifier code, amplifier output control parameter data, and amplifier control value data.

9. An apparatus as claimed in claim 1 , wherein the amplifier unspecific power control data is usable in respect of a number of different amplifier circuits.

10. An apparatus as claimed in claim 1 , wherein a look-up table comprises the amplifier unspecific power control data.
