1 Understanding the HP/Agilent

8922 GSM HSCSD Test System

This chapter provides an overview of the HP/Agilent 8922 GSM HSCSD Test System.

Understanding the HP/Agilent 8922 GSM HSCSD Test System

Getting an overview of the HP/Agilent 8922 GSM HSCSD Test System

The HP/Agilent 8922 GSM HSCSD Test System option #K09, is ideal for mobile testing in research and development, and can also be used in manufacturing test applications. The HP/Agilent 8922 GSM HSCSD Test System option #K09 consists of two HP/Agilent 8922 P systems connected together in a master/slave setup as shown below.A single unit version of the HP/Agilent 8922 GSM HSCSD TestSystem (option #K17), ideal for manufacturing and service test, is also available.

Understanding the HP/Agilent 8922 GSM HSCSD Test System

Getting an overview of the HP/Agilent 8922 GSM HSCSD Test System

The HP/Agilent 8922 GSM HSCSD Test System is used either as a stand-alone instrument controlled manually via the front panel user interface, or as part of an automated test system controlled remotely over the GPIB bus using a PC or workstation. Note that manual and remote operation are not possible simultaneously.

The HP/Agilent 8922 GSM HSCSD Test System provides one conﬁguration consisting of two uplink and two downlink timeslots (2x2) or two downlink and one uplink timeslot (2x1). Data rates of 9.6 and 14.4 kbit/s on each timeslot are supported. The timeslots used are always adjacent, with the master channel in the ﬁrst of these slots. You are able to independently change the uplink and downlink power levels on the two downlink timeslots and make measurements on either timeslot as required.

Note that the system does not perform any data channel decoding on the uplinks and only provides pre-coded data on the downlinks. The current system only allows transparent data links, which means that the RLP data layer is not supported.

Operating modes The master unit operates in Active Cell Mode and is responsible for all

protocol messages. The mobile must therefore camp to the master unit, establish the call to it and receive channel assignment commands from it etc.

The slave unit operates in Test Mode. It generates a second downlink TCH and can analyze a second uplink TCH (if it exists). The slave unit remains in synchronization with the master unit at all times.

The BCH of the slave unit includes information to prevent the mobile from camping to the slave, thus ensuring that the mobile camps to the master unit. To discourage unsynchronised operation, the slave unit does not generate a downlink TCH unless it has received a reset signal from the master unit.

Chapter 1 3

Understanding the HP/Agilent 8922 GSM HSCSD Test System

Features

The HP/Agilent 8922 GSM HSCSD Test System supports the following features. The full range of features available in speech mode is maintained.

• Support of fully variable power level of each active timeslot on the downlink. This provides complete freedom to control the amplitude of the downlinks.

• Support of fully independent power control by protocol of each active timeslot on the uplink. This allows you to independently set the Tx level of each timeslot.

• Transmit SACCH in each active slot on the downlink (call maintenance + power control) according to ETSI multi-frame structure. This provides a SACCH frame in the correct position on both the downlink TCHs.

• All existing measurement functionality and performance maintained and performed on any slot independently. Youcan select either uplink slot to measure, either by selecting one instrument or via a ﬁeld on the user interface.

• Support of protocol to set up a 2x2 or 2x1, 9.6 or 14.4 kbps timeslot uplink/downlink data channel (both Mobile Originated and Mobile Terminated). The existing HP/Agilent 8922P functionality to originate or receive a call is still available.

• Support of burst-by-burst (fast) BER test on both 14.4 kbps timeslot data channels simultaneously. The existing bit error test functionality of the HP/Agilent 8922P is available in speech mode only.

• You can select any timeslot for the master channel in the range 2 through 5. The slave timeslot is always the following slot. Any ARFCN can be used in any of the currently supported bands (GSM900, E-GSM, DCS1800 and PCS1900).

• Dual-band assignment supported. The existing HP/Agilent 8922P functionality to perform a dual-band assignment is maintained.

• All 2x2 HSCSD calls are in transparent mode and all 2x1 calls are in non-transparent mode.

GSM HSCSD Test System

This chapter describes how to connect and set up the HP/Agilent 8922 GSM HSCSD Test System.

Setting up the HP/Agilent 8922 GSM HSCSD Test System

Before you start

WARNING The HP/Agilent 8922 is a Safety Class 1 product (provided with a

protective earth terminal). A safety earth ground must be provided from the mains power source to the product input wiring terminals, power cord, or supplied power cord set. Whenever it is likely that the protection has been impaired, the HP/Agilent 8922 GSM HSCSD Test System must be made inoperative and be secured against any unintended operation.

WARNING If the HP/Agilent 8922 is to be energized via an external

autotransformer for voltage reduction, make sure that the common terminal is connected to the neu tral pole of the power source.

Before you connect the two HP/Agilent 8922 P systems together to form the HP/Agilent 8922 GSM HSCSD Test System, ensure that both HP/ Agilent 8922 P systems are connected and calibrated as described in the HP/Agilent 8922 Multi-Band Test System Supplementary User’s Guide. For details on the HP/Agilent 8922P front panel connections, see the HP 8922 Multi-Band Test System Supplementary User’s Guide.

The RF ﬂow must be combined and split between the two HP/Agilent 8922P systems. This is done by connecting the supplied RF link cable (08922-61185) between the Coupled RF Port on the dual band HP/ Agilent 83220 of the master unit and the GSM/DCS/PCS RF In/Out port on the HP/Agilent 83220 of the slave unit.

Making the rear panel connections

Before connecting the two HP/Agilent 8922 P systems to form the HP/ Agilent 8922 GSM HSCSD Test System, ensure that both HP/Agilent 8922 P systems are connected and calibrated as described in the HP/ Agilent 8922 Multi-Band Test System Supplementary User’s Guide. See the HP/Agilent 8922 GSM Test Set User’s Guide and the HP/Agilent 83220 User’s Guide for details on the rear panel connections.

Tomake the rear panel connections of the HP/Agilent 8922 GSM HSCSD Test System:

Step 1. Connect the system bus cable from the master unit to the slave unit (the

end with the BNC connection must be connected to the master unit). If you are not connecting the BNC connector on the system bus cable to

for example, a spectrum analyzer, then terminate the connection using the BNC terminator provided.

Step 2. Connect the GPIB cable from the GPIB port on the master unit to the

GPIB port on the slave unit.

NOTE If you are operating the HP/Agilent 8922 GSM HSCSD Test System

manually do not connect another GPIB controller to the GPIB bus. The master unit operates as the controller and another device attached to the GPIB bus results in conﬂicts on the GPIB bus.

Step 3. Connect the 10 MHz reference cable from the 10MHz OUT port on the

master unit to the Ref IN port on the HP/Agilent 83320 of the slave unit. The HSCSD connections are shown below.

Calibrating the overall system

There is an RF loss through the system from the slave unit's reported output level to that observed by the mobile due to cable loss and a nominal 7 dB loss through the system. Therefore once you have connected the HP/Agilent 8922 GSM HSCSD Test System and calibrated each unit individually (see the HP/Agilent 8922 Multi-Band Test System Supplementary User’s Guide), you must calibrate the overall system to account for these losses. To do this you need to adjust the RF Level

Offset ﬁeld on the Conﬁg screen. To determine the necessary RF Level Offset adjustments:

Step 1. Connect a mobile to the HP/Agilent 8922 master unit and set up a call as

described in Chapter 3 , “Manual operation,” on page 15.

Step 2. Go to HSCSD Control screen on both units and set each unit to measure

the master uplink slot.

Step 3. Go the Conﬁg screen on both units and set the RF Lev Offset so that

the transmitted power level of the master and slave units are the same. When the transmitted power level is the same on both the master and

slave units the system is calibrated to account for its RF losses.

NOTE RF losses may be different for GSM and DCS radio modes, therefore it is

recommended that you perform calibration for both GSM and DCS.

NOTE You must calibrate the system whenever any of the following occur:

• The HP/Agilent 8922 GSM HSCSD Test System is ﬁrst set up.

• Any hardware component in the system is changed (HP/ Agilent 83220 and/or HP/Agilent 8922).

• Different IF Link or Aux RF In/Out cables are used.

• After a RAM Initialize or Firmware Upgrade.

• You need to troubleshoot the system or localize faults.
