The maximum output power of a mobile is specified by its power class (Mobile Power Class). This
information is queried by the sequence control from the DUT and influences the choice of tolerance.
Originally, power class 1 and PCL 0 were fixed at 43 dBm. Since no mobiles operate in this power
class, the maximum output power of a GSM900 mobile is limited to 39 dBm.
Example:
A mobile of power class 4 is to be measured. The maximum mobile output power corresponds to 33
dBm or PCL 5. The ± 2.0 dB tolerance of PCL 5 is therefore used in this case.
With GSM1800 and GSM1900, four PCL-specific tolerances can be specified. They are entered in the
four fields of the Limits Average Power dialog window. The modified dialog window is displayed when
one of the two networks is selected in the Configure Network dialog window.
PCLs 29, 30 and 31 defined by GSM1800 are not supported by the CTSgo program.
PCLs 30 and 31 defined in GSM1900 are not supported by the CTSgo program.
As with GSM900, the highest mobile power level is weighted with Tolerance 1.
Power classes of GSM1800 and GSM1900 can be obtained from the two tables below. Power classes
which are not supported appear on a dark background.
