Zero the Power Meter

The HP/Agilent 8922 and HP/Agilent 83220 each have independant power meters. When testing a mobile in the GSM900 (and E-GSM) band the HP/Agilent 8922 power meter is used to measure the transmitted power levelfrom the mobile, and when testing a mobile in the DCS1800 band the HP/Agilent 83220 power meter is used. To ensure that both instruments’ power meters function correctly, they must be zeroed before instrument operation and then regularly in subsequent operation to guarantee continued measurment accuracy.

NOTE: Failure to regularly zero the HP/Agilent 8922 and HP/Agilent 83220 power meters results

in measurment inaccuracies after a long period of time. Although both instruments are always zeroed prior to shipping from the factory, they still require their power meters to be regularly zeroed to guarantee measurement accuracy. It is recommended that the power meters are zeroed on a weekly basis as a minimum. Note that it is not a requirement to zero the power meter for every mobile that is tested.

To Zero the Power Meter of the HP/Agilent 8922

1 Ensure that no external instruments, test devices or mobiles are connected to the HP/

Agilent 8922 Multi-Band Test System.

2 Switchon the HP/Agilent 8922 Multi-Band Test System, navigateto the CONFIGURE

This procedure is identical to that of a Standard HP/Agilent 8922 Test System.

1 Once the mobile has been connected and camped on to the HP/Agilent 8922

Multi-Band Test System, key in any number on the mobile.

2 Now initiate the call from the mobile. The display on the HP/Agilent 8922 should now

show that the call status is CONNECTED.

Potential Problems

If a call is not established, the uplink power may differ from the HP/Agilent 8922’sexpected input level. The most likely reason for this type of problem is that the mobile or the IF Link cable has not been calibrated. Refer to Calibration Routine on page 7 for more details on calibrating the IF Link cable.

Screens

Dual Band Control Screen

5. Downlink Amplitudes

These 3 ﬁelds control the amplitudes of the downlink channels. These ﬁelds operate differently depending on which band is being used.

E-GSM900 Band

DCS1800 Band

When the trafﬁc channel is in E-GSM900 band, the GSM BCH & TCH ﬁeld will have an immediate effect. This ﬁeld is identical to the RF Gen Amplitude ﬁeld on the Cell Conﬁguration screen.

The

GSM BCH Atten. and DCS TCH ﬁelds have no effect until the trafﬁc channel

moves to the DCS1800 band.

GSM BCH & TCH

Default -85 dBm Range -6.0 dBm to -127.0 dBm (no electronic attenuation)

-7.0 dBm to -127.0 dBm (with electronic attenuation)

When the trafﬁc channel is in the DCS1800 band, the GSM BCH & TCH ﬁeld has no effect until the trafﬁc channel moves back to the E-GSM900 band.

The GSM BCH Atten. ﬁeld controls the attenuation of the E-GSM900 BCH. The

DCS TCH ﬁeld controls the amplitude of the downlink trafﬁc channel. Both these

ﬁelds have an immediate effect.

GSM BCH Atten. Default 20 dB

Range 0, 10, 20, 30, 40, 50, 60, 70 dB

DCS TCH Default -85.0 dBm

Range -127.0 dBm to -12.0 dBm

GSM BCH Atten. and Nominal Ampl.

When the TCH is in the DCS1800 band, the BCH remains in the E-GSM900 band. The amplitude of this BCH is nominally -60 dBm. This level can be changed by introducing increasing levels of attenuation. For example, selecting

GSM BCH Atten. will reduce the BCH amplitude to -90 dBm nominal.

30 dB

NOTE: Although the absolute BCH level is a typical specification, the relative changes in

amplitude are more accurate. To determine an accurate absolute level, refer to ‘Appendix A - Establishing Absolute GSM BCH Power Level’ on page 81 for more information.

GPIB Commands for Including Power Zeroing in an Automatic Test Routine

The following GPIB commands are recommended for inclusion in the initialization routine for testing Dual-Band type mobiles. For details on zeroing the HP/Agilent 8922 and HP/Agilent 83220 power meters manually,see “Zero the Power Meter” on page 1-9.

OUTPUT 714; “CONF:RADIO ‘DCS1800’

OUTPUT 714; “CW:PMZ”

OUTPUT 714; “CONF:RADIO ‘E-GSM’ OUTPUT 714; “CW:PMZ”

Zeroing power in the above order ensures that the Test Set is returned to E-GSM Radio Type in preparation for testing of a Dual-Band mobile.

Note that the command “CW:PMZ” is equivalent to “DSP:AMPL:PMZ”.

AppendixA- Establishing Absolute GSMBCH Power Level

Appendix A - Establishing Absolute GSM BCH Power Level

Procedure

The following procedure can be used for determining the absolute GSM BCH peak power level. The GSM BCH power level is the output from the RF In/Out port along with the TCH. This output is used to synchronize calls when switching from E-GSM900 to DCS1800 (Dual Band mode).

It is assumed that the operator is familiar with operating the HP/Agilent 8922 Multi-Band Test System and HP/Agilent 8560 Series Spectrum Analyzers.

Equipment

• HP/Agilent 8922 Multi-Band Test System

• HP/Agilent 8560 Series Spectrum Analyzer

• N-type to N-type cable

Equipment Set up

• Ensure the coupled RF In/Out has a 50 Ohm load connected.

• Connect the HP/Agilent 8922 Multi-Band Test System and ensure the system is opera-

tional.

• Connect the Spectrum Analyzer to the HP/Agilent 8922 Multi-Band Test System using

the

N-type connecting cable. Connect from the HP/Agilent 8922 Multi-Band Test System

RF In/Out port to the Input port of the spectrum analyzer.

• Switch on all instruments, allowing 30 minutes warm up time.

HP/Agilent 8922 Set up Procedure

1 Select CONFIG screen. 2 Ensure the Compatible mode is set to 8922P or 8922X. If the mode is not at either

of these settings, change this field and switch the system off then on again.

3 From the Cell Status screen, set the OPERATING MODE to E-GSM. 4 Set the OPERATING MODE (second field) to TEST MODE. 5 From the CONTROL menu, set the Broadcast On Channel to (939 MHz). 6 Set the Dual Band field to (This will change the OPERATING MODE

to DCS1800, Dual Band).
