•set the slave GPIB address to match the address of the slave unit
•make sure that the addresses of the slave and master units are different
•make sure that no other GPIB controller is active and attached to the system
If you are operating the HP/Agilent 8922 GSM HSCSD Test System manually do not connect another GPIB controller such as a PC to the GPIB bus. The master unit operates as the controller and any other device attached to the GPIB bus can result in conflicts on the GPIB bus.
Selecting HSCSD Slave sets the GPIB address of the instrument to 15 to match the default slave GPIB address of the master unit.
If the HP/Agilent 8922 GSM HSCSD Test System is not fitted with a new 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 HP/Agilent 8922’s HOP Controller ROM, see “Upgrading the HOP Controller ROM and Firmware” on page 75.
The Instrument type field is reset to the default in the event of a reset or power cycle. Setting this field also resets all the default values on the HSCSD Control screen.
