Manual operation

Configuring the system

The slave unit’s GPIB address is now automatically set to 15 (seen in the

 

 

 

IO Config screen) which is the default Slave Address setting on the

 

 

 

master unit. The slave unit’s GPIB address must be the same as the

 

 

 

Slave Address setting on the master unit and this helps to ensure this.

 

 

 

The slave unit’s Operating Mode is also automatically set to Test Mode

 

 

 

(seen in the Cell Status screen).

 

 

 

If the HP/Agilent 8922 GSM HSCSD Test System is not fitted with a new

NOTE

 

 

 

 

 

HOP Controller ROM, selecting HSCSD Master or HSCSD Slave results

 

 

 

in the error Hardware portion of upgrade not present. The test set

 

 

 

will allow HSCSD operation, however the downlink signal could be

 

 

 

scrambled when the TCH ARFCN is on or near the master or slave unit’s

 

 

 

BCH ARFCN. For details on upgrading the HOP Controller ROM, see

 

 

 

Appendix A , “Upgrading the HOP Controller ROM and Firmware,” on

 

 

 

page 75

 

 

 

 

Step 2. On the master unit, go to the CONFIGURE screen and set the Instrument

 

 

 

Type to HSCSD Master.

 

 

 

The master unit’s Operating Mode is now automatically set to Active

 

 

 

Cell Mode (seen in the Cell Status screen).

 

 

 

The message Frame reset sent appears in the top left-hand corner of

 

 

 

the master unit’s screen indicating that the master unit has sent the

 

 

 

frame reset to the slave unit.

 

 

 

Note that the Slave Address field is set to 15 as default. This must

 

 

 

match the slave unit’s GPIB address, therefore if you change the Slave

 

 

 

Address setting on the master unit, you must also change the slave

 

 

 

unit’s GPIB address to match.
