This chapter introd uces you t o the HP 8320 6A TIA/EIA-136 Test System and will show you how to prepare the Test System to test a mobile transceiver. Use of the HP 83236B PCS Interface is also discussed.

This manual is written for those who are already familiar with the HP 8920B RF Communications Test Set. If you want to learn more about using the Test Set itself, refer to the HP 8920B User ’s Guide.

Chapter 1, Getting Started

About the Cellular Adapter

This Cellular Adapter is a test set adapter for the HP 8920B RF Communications Test Set. It works with the Test Set to test mobile transceivers built according to the TIA/EIA-136 standard. The Test Set and the Cellular Adapter are collectively referred to as the Test System.

TIA/EIA-136 is a standard which describes a Ti me Division Multiple Access (TDMA) cellular communicatio ns sy stem. The major feature which dis ti ngui sh es TIA/EIA-136 from its predecessor TIA/EIA-627 is the addition of a Digital Control Channel (DCCH). To learn more about TIA/EIA-136, refer to the TIA/ EIA standard, or read Chapter 10, “TIA/EIA-136 Basics,” on page 265.

HOW OFTEN SHOULD YOU ZERO THE AVERAGE POWER METER?

A frequently zeroed Test System will ensure the highest measurement accuracy. The Zero Power function measures the input power with no cables connected to

the Test System. The input power is measured for all gain settings. These measurements are stored in static RAM, and the Test System uses them to calculate any offsets when measu ring power with a DUT attached. The values ar e updated whenever you zero the power meter, and the latest values are stored for the life of the static RAM backup battery.

You sh ould zero power frequently if the Test System is still warming up, about two to three times within the first two hours. You should zero power occasionally even if the Test System is on continu ously. (Occasionally can mean daily , weekly or monthly, as you choose).

Zeroing TX Power

TX Power and A verag e Power are dif ferent measure ments. TX Power is zero ed by running a ROM program in the Test Set when the Cellular Adapter is attached. See “TX Power” on page 139 for a description of the TX Power measurement.

Connecting a Mobile

DO NOT CONNECT TO THE ANT IN PORT ON THE FRONT PANEL

A single RF connection is used to test th e RF perfo rman ce of a mobile. If you are not using a PCS Interface, you connect the antenna port of the mobile to the RF IN/OUT port of the Test Set. If you are using a PCS Interface, you connect the antenna port of the mobile to the RF IN/OUT port of the PCS Interface. Audio test connections are the same in all cases.

Most manufacturers have specifi c connector s which can connec t the audi o and the RF signal to the Test Set. Figure 5 on page 1 38 shows ho w to conne ct a mobile t o a Test System without using a PCS In te rf ace . Fi gure 6 on page 1 39 shows how to connect a mobile to a Test System that includes the PCS Interface.

Rear-panel connections for the Ce ll ular Adapter and PCS Int erf ace are in Chapter

11, “Installing the Cellular Adapter,” on page 285.

Do not connect the antenna of the mobile to the ANT IN port on the front panel of the Test Set. This will cause the overpower protection circuitry to activate when the mobile is transmitting. Refer to the HP 8920 RF Communications Test Set User’s Guide for more information.

About the PCS Interface

Installing the PCS Interface

IMPORTANT: TURNING ON THE PCS INTERFACE

The PCS Interface is connected by a serial cable to the Test Set. Interface control

is provided by the Test Set’s internal IBASIC controller. The timebas e reference for the PCS Interface (and Cellular Adapter) comes from the Test Set. No Frame Clock connection is needed.

System Connectivity software is used to verify operation after connecting the PCS Interface to the Test System. The software is run from the PCMCIA card shipped with the PCS interface. Be sure to set the HP-IB/Serial switch on the PCS Interface to the

Ser position before turning the PCS Interface on and running the

test. During the test, you are asked to select seri al or HP-IB control of the interface. Sele ct Seri al Contro l and fol low the remaining instruct ions di splayed on the Test Set’s screen.

Instructions for connecting the PCS Interface and running the connectivity software are provided in the HP 83236B PCS Interface Operating Manual shipped with the interface. Connections to the interface are provided in “PCS

Interface Connections” on page 288.

In order for the Test Set to detect the connected PCS Interface, the PCS Interface must already be turned on while the Test Set is powering up.

Using the PCS Interface

DO NOT USE AUTOTUNING WITH THE PCS INTERFACE

After installing the PCS Interface and successfully running the System Connectivity test software, you need to perform some additional operations to properly use the interface. These operations include:

1. Initializing the PCS Interface for operation with the Test System.

2. Entering path losses into the PCS Interface.

3. Specifying the type of mobile your are testing.

4. Compensating for temperature changes.

5. Selecting the correct vocoder.

Initializing the PCS Interface

This must be done every time you turn the instruments on, even if you are not testing PCS mobiles.

Set. Also, set the CALL CONTROL screen to test a mobile.

After configuring the Test System to meet your test needs, you can save the configuration for later use in a SAVE/RECALL register. This eliminates the need to manually reconfigure the Tes t System each time you use it.

There are two ways to save your test configuration:

1) Press SHIFT, RECALL (SAVE), and enter a name (such as DCCH_PCS). The next time you turn the Test System on, you can press RECALL and select the name you entered. The Test System returns to the same state it was at when you saved the settings.

2) Press SHIFT, RECALL (SAVE), and enter the name “POWERON”. The next time you turn the Test System on, the Test System will automatically re -establish all settings you saved.

CAUTION: SAVING SETTINGS FOR PCS OPERATION

Emulating a Base Station

To use SAVE/RECALL registers, you must use the same hardware configuration present at the time the register is created. If you save instrument settings when a PCS Interface is connected to the Test Set, the Test Set expects to detect the presence of the interface when the register is recalled. If the PCS Interface is not connected to the Test Set when the register is recalled, or the interface is turned off, a non-recoverable firmware error occurs. If you encounter this error, the Test Set must be turned off, and the PCS Interface must be connected and turned on, before the Test Set can power up normally and function cor rectly.

Authentication

The process of testing DCCH authentication (TIA/EIA-136) through the Call Processing Subsystem req uires the use r to synchroni ze the base st ation and mobil e station. This synchronization requires that the base station and the mobile station possess two pieces of shared secret data (SSD) to confirm a valid call. The first piece is the

A-key. The A-key is a secret 26-digit number stored in the mobile station’s semi-

permanent memory. The following sections describe how to:

• Initialize Call Processing with Authentication

• Page a Mobile Station with Authentication

• Originate a Call with Authentication

• Perform an SSD Update

• Perform a Unique Challenge

DTC AND AVC AUTHENTICATION SETTINGS

These procedures assume you understand how to configure the Test System to emulate a base stat ion. (See “Configur e the Test Set to Emulate a Base Sta tion” on

page 64)

The authentication settings used when connected on a DTC are somewhat different than those used on an AVC. Basically, the RANDSSD data and A_KEY information are entered differently. Otherwise, operation is the same.

Making Measureme nts

This chapter discusses the difference between data and measurements. It also explains how to read data and make measurements.

Making Measurements

Chapter 4, Making Measurements

How to Read Data and Make Measurements

Most measurements are made directly by toggling the Data/Meas field. Measurements are available in both the CALL CONTROL screen and the DIGITAL MEASUREMENT screen. BER is only available in the DIGITAL MEASUREMENT screen. MAHO is only available in the CALL CONTROL screen. Some measurements, such as BER and Average Power, have special conditions that must be met before the measurement is accurate. These measurements are described in detail later in this chapter.

The Difference Between Data and Measurements

Data is the contents of messages tr ansmit ted or rece ived by the m obile or Test Set. Data usually has no units associated with it. Some data is listed below.

Data

• phone number

•ESN

•SCM

Measurements are evaluations of the Device Under Test (DUT). Measurements typically have units associated with them. Some measurements are listed below.

Measurements

•EVM1 (%)

• adjacent channel power (dB)

•BER (%)

• Average Power (requires HP 8920B Option 006 or PCS Interface)

• TX Power
