Frequency Banded Parameters

Last updated: December 2, 2008

The majority of the test set's parameters are active regardless of the frequency band selected. There are a number of parameters that allow you to specify a band; DCS, EGSM, GSM450, GSM480, GSM750, GSM850, T-GSM810, PCS, PGSM or RGSM. These exceptions are called frequency banded parameters.

Frequency banded parameters are activated upon selection of a band. Parameters that select frequency bands include cell band and traffic band (see Band Selection Parameters ).

You can set parameter values for a band that is not currently selected, and the test set stores the settings for future use. For example, during a call on the PGSM band, the MS TX level can be set to 10 for the DCS frequency band. When a handover (see How the Test Set Performs a Dualband Handover ) to the DCS band is made, the MS TX level of 10 for DCS will already be set.

If you do not specify a frequency band when setting frequency banded parameters, settings to the parameter are made in the currently selected band.

GSM Programming Example

This section provides an example of how to use frequency banded parameters.

The following procedure assumes that an active link is established between the test set and the mobile station. See Establishing an Active GSM Link with the Mobile Station .

 
10  OUTPUT 714;"CALL:TCH:PGSM 124" !Sets traffic channel to 124 for PGSM band.
20  OUTPUT 714;"CALL:MS:TXL:PGSM 7" !Sets the mobile station uplink power control
30                                  !level to 7 for PGSM band.
40  ! Now set up frequency banded parameters for DCS band.
50  OUTPUT 714;"CALL:TCH:DCS 850" !Sets traffic channel to 850 for DCS band.
60                                !The default traffic channel for the DCS
70                                !band is 30.
80  OUTPUT 714;"CALL:MS:TXL:DCS 5" !Sets the mobile station uplink power control
90                                 !level to 5 for the EGSM band. The default level is
100                                !15.
110 ! Now change the traffic channel band to DCS. The TCH and uplink power control level
120 ! parameters are set to the values you specified above, not the default values.
130 OUTPUT 714;"CALL:TCH:BAND DCS"
140 ! Now query the traffic channel and uplink power control level.

170 OUTPUT 714;"CALL:MS:TXL?"
180 ENTER 714;Tx_lev

210 PRINT "The default Tx Level is 10. The current Tx Level is: ";Tx_lev
