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.

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 Mod e 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 Mod e. 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.

Features
Fea tu r es
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.
•

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.
To make 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
Ca libr a tin g th e over a ll 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
Offsetfield on the Config screen. To determine the necessary RF Level
Offsetadjustments:
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 Offsetso 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
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.
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.

To configure the HP/Agilent 8922 GSM HSCSD Test System for manual
operation, proceed as follows.
NOTE
NOTE
You must configure the slave unit first as a frame reset is sent from the
master unit to the slave unit as soon as the master unit is activated. The
slave unit must be ready to receive this frame reset.
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.
Step 1. On the slave unit, navigate to the CONFIGscreen and set the Instrument
Typeto HSCSD Slave.

Configuring the system
The slave unit’s GPIB address is now automatically set to 15 (seen in the
IO Configscreen) which is the default Slave Addresssetting on the
master unit. The slave unit’s GPIB address must be the same as the
Slave Addresssetting on the master unit and this helps to ensure this.
The slave unit’s Operating Modeis also automatically set to Test Mode
(seen in the Cell Statusscreen).
NOTE
If the HP/Agilent 8922 GSM HSCSD Test System is not fitted with a new
HOP Controller ROM, selecting HSCSD Master or HSCSD Slaveresults
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 CONFIGUREscreen and set the Instrument
Typeto HSCSD Master.
The master unit’s Operating Modeis now automatically set to Active
Cell Mode(seen in the Cell Statusscreen).
The message Frame reset sentappears 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 Addressfield is set to 15 as default. This must
match the slave unit’s GPIB address, therefore if you change the Slave
Addresssetting on the master unit, you must also change the slave
unit’s GPIB address to match.

Manual operation
Establishing a call
Esta blish in g a ca ll
You establish a call in the same way as for a speech call.
Step 1. Ensure that the master timeslot is the timeslot currently being
measured on the master unit.
To do this, navigate to the HSCSD control screen on the master unit and
set the Measurefield to Master. If you do not do this the HP/Agilent 8922
does not see the signalling from the mobile, and call set up fails.
Step 2. Configure the call by navigating to the HSCSD control screen on the
master unit, and setting Call Typeas a 2x2 or 2x1 and Data Rateto 9.6
or 14.4 kbits/s as required.
Step 3. Connect the mobile to the RF IN/OUT port located on the front panel of
the master unit’s HP/Agilent 83220 (see the HP/ Agilent 8922 Multi-
Band Test System Supplementary User’s Guide for more information
about this port).
Step 4. Switch on the mobile.
The mobile now camps onto the broadcast channel.
Step 5. Once the mobile is connected and successfully camped on to the master
unit, initiate the call from the mobile (for example, by pressing SENDon
the mobile, or by pressing ORG CALLon the HP/Agilent 8922 master
unit). The display on the HP/Agilent 8922 now shows that the call status
is CONNECTED.
If the call cannot be established, it may be because the uplink power may
differ from the HP/Agilent 8922’s expected input level. The most likely
reason for this type of problem is that the mobile or the IF Link cable has
not been calibrated. For details on calibrating the system “Calibrating
the overall system” on page 14.

Making measurements
Ma k in g m ea su r em en ts
Once a call is established, you can make measurements as before—see
the HP/ Agilent 8922 User’s Guide for more details. Note however that
there are two new factors which you need to consider: choosing which
timeslot to perform measurements on, and performing BER on the two-
unit system.
Ch oosin g w h ich tim eslot to m ea su r e
Any HSCSD instrument can measure the master or the slave timeslot.
This selection is made on the HSCSD control screen, and the
measurements on this screen include a reminder of which slot is
currently being analysed. On other screens, where this reminder is not
present, you must be aware of which slot you are measuring.
Mea su r in g BER
To perform BER, one instrument starts a measurement, while the other
makes the measurement. Specifically, to perform BER on the slave
timeslot, you must start the BER measurement on the master unit
because it is the master unit which performs the signalling to place the
mobile in loopback mode. Once this is done, the BER measurement must
be started on the slave unit, where it will then run as normal. After the
measurement is complete, and the master unit is returned to a different
screen, the HP/Agilent 8922 signals the mobile and takes it back out of
loopback mode.
Ch a n gin g ba n d a n d m a k in g m ea su r em en ts in th e
E-GSM900 a n d DCS 1800 ba n d s
Changing band and making measurements in the E-GSM900 and

and slave amplitudes. Below this field there is a read-only reminder of
the absolute level of the slave TCH.
Note that the resultant absolute amplitude must lie within the normal
RF generator limits (-127.0 thru +1.0 dBm). The error Disallowed due
to pulse mod configurationis returned if these limits are exceeded.
On a master unit, changing the Slave offsetfield has no effect other
than copying the value to the slave unit when being operated manually.
On a slave unit, changing the Slave offsetfield changes the downlink
amplitude of the unit. This field, when added to the master downlink
amplitude (see page 27) always has the same value as the RF I/O
generator amplitude.

On a master unit, the Master Tx levelfield requests a new transmit
level for the uplink master TCH. On a slave unit, this field does not make
this request.
If the instrument is operating in standard mode, setting this field
changes the master mode (see page 35) to MS TX Lev, then calculates
and sets the master’s expected input level (see page 34). If the
instrument is operating in compatibility mode, setting this field only
changes the master’s expected input level when the control type for the
master is set to MS TX Lev.

One extra field, labelled Loopback, appears in the Fast Bit Error screen,
when the HP/Agilent 8922 is in 2x1 mode.
Figu r e 4-3
Fa st BER scr een
The Loopbackfield is a toggle field and allows the choice of either master
or slave. This instructs the mobile to either loopback the master channel
on the downlink to the master uplink or loopback the slave downlink to
the master uplink.
Note that toggling the Loopbackfield does not immediately instruct the
mobile to perform a loopback using the contents. Entering the screen
sends the command to the mobile to close the loop. It is therefore
necessary to enter the screen with this field set to loopback the downlink
channel of choice.
NOTE
When performing Fast BER on the slave channel, it is necessary to start
the measurement on the master unit because the master unit controls all
the signalling with the mobile). As a result, this also starts a Fast BER
measurement on the master unit which should be ignored.

Introduction
In tr od u ction
The general principle of operation is that the settings on the slave unit
are relative to the settings on the master unit which allows the manual
and remote interfaces to operate in the same way. It is therefore
necessary to always consider the relationship between the two timeslots.
Call setup and changing channels are handled by the master unit.
However, it is vital that the slave unit remains on the same channel and
timeslot (offset by one) as the master unit. Unlike the manual user
interface, where a change made on the master unit is copied to the slave,
controlling the system remotely involves taking control of both units. As
most of the settings on the slave unit are relative to the master unit, the
slave unit must know the configuration of the master unit. The following
command sequence is a general example of how this is achieved.
MasterAddr=715
SlaveAddr=716
OUTPUT MasterAddr;”HSCSD:MASTER:COMMAND <parameters>”
OUTPUT SlaveAddr;”HSCSD:MASTER:COMMAND <parameters>”
OUTPUT SlaveAddr;”HSCSD:SLAVE:COMMAND <parameters>”

HSCSd :MASTer :TCH:ARF Cn
Description
Setting this during a call forces a channel assignment to the given
channel. Note that existing channel assignment commands sent to a
master or single unit have the same effect. In particular, a dual band
assignment must be performed using the existing dual band commands.
If the measurement timeslot is not set to “Master”, attempting to
perform a channel assignment on a master or single unit will produce an
error, and the setting will be ignored. The error message is Select
Master to measure before signalling mobile. When the system is
idle (that is, not on a call) this sets the channel which will be used when
the next call is established. This command must also be sent to the slave
unit.

The procedure for establishing a call is the same as for speech. Note
however, that you must be measuring the master uplink in the master
unit.

Once a call is established, measurements are made as before.
Any HSCSD instrument can measure the master or the slave timeslot.

BER on a two unit system which is in 2x1 mode is complicated by the fact
that the measurement must be started using the master unit, which
performs the signalling with the mobile phone. Specifically, to perform
BER on the slave timeslot, you must start the BER measurement on the
master unit. This is because it is the master system which performs the
signalling to place the mobile in loopback mode. Once this is done, the
BER measurement must be started on the slave unit, where it then runs
as normal. After the measurement is complete, the master unit returns
to a different screen which causes the HP/Agilent 8922 to signal the
mobile and take it back out of loopback mode.

Performing a channel assignment is a single instruction. Note that the
slave unit must be kept in step with the master and the master must be
measuring the master uplink prior to performing a channel assignment.
Note also that a dual band channel assignment can be performed using
the existing procedures.

Changing Tx Level is also simple. Note that Tx Level is not relative to
the master setting, so the master level does not have to be sent to the
slave unit. It does not matter which timeslot is being analysed at the
time.

Example code showing a dual-band handover from E-GSM to DCS
Exa m p le cod e sh ow in g a d u a l-ba n d h a n d over
fr om E-GSM to DCS
Some example code is listed below which performs a dual-band handover
from E-GSM to DCS on an HP/Agilent 8922 GSM HSCSD Test System.
The technique is to use the standard dual-band command sequence, but
send this to both HP/Agilent 8922 units. Note that after ending a call,
the slave unit remains in the DCS band, therefore it is good practice to
set the radio band prior to starting the HSCSD call.
