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 Test System (option #K17),
ideal for manufacturing and service test, is also available.

Chapter 1 3
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.

Understanding the HP/Agilent 8922 GSM HSCSD Test System
Features
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. You can 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.

Before you start
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
