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 |
|
|
| 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. |
