This application guide describes manual and automated procedures for testing Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA) Standard 136 mobile phones with the HP 83206A Cellular Adapter, HP 8920B Test Set, and the HP 83236B PCS Interface (if PCS mobiles are being tested). Each topic includes a description, test conditions, a manual procedure and a sample HP BASIC program.

Making Measurements

This document is intended to be used as a tutorial and a quick reference document. The

tests and procedures shown are those most commonly used by mobile manufacturers.

About the TIA/EIA 136 and 137 Standards

These standards describes a Time Division Multiple Access (TDMA) cellular communications system. The major feature that distinguishes the TIA/EIA 136 and IS-137 standards from its predecessors, TIA/EIA-54B and 55, is the addition of a Digital Control Channel (DCCH).

About the HP 83206A Cellular Adapter

The HP 83206A works with the HP 8920B to perform call processing, transmitter tests, and receiver tests on DAMPS (TIA/EIA 54) and DCCH (TIA/EIA 136) mobiles. See IS-137

Test Descriptions on page 113.

The HP 83206A is controlled by the host HP 8920B Test Set. Once installed, the adapter becomes part of the measurement path for the Test Set.

Without the Cellular Adapter, the Test Set can still test mobiles using standard analog modulation schemes, such as AMPS and NAMPS.

About the HP 83236B PCS Interface

The PCS Interface extends the mobile test frequency range into the PCS band of 1.7 GHz to 2.0 GHz. The interface is controlled entirely by the Test Set using a serial cable connection between the instruments.

The Test Set detects the presence of the PCS Interface when the Test Set is powered-up. However, the PCS Interface is not automatically enabled at power up. Therefore, you must

enable the PCS Interface on the Test Set’s CONFIGURE screen before making PCS or cellular band measurements through the interface. Enabling the interface tells

the Test Set that all measurements will be made through the interface and not through the

Test Set’s own RF IN/OUT port.

Measuring High Level Analog Carriers

If you need to make high level power measurements (>1 Watt) on an analog carrier, disable the interface on the CONFIGURE screen and connect your signal directly to the Test Sets RF IN/OUT port. Do not exceed the level printed under the port.

Using the PCS Interface

The PCS Interface must first be connected to the test set as shown in the instructions for TDMA subscriber (mobile) testing in the HP 83236B Operating Manual.

The test set looks for the PCS Interface through its serial control connection when the test set is first turned on. Always turn the PCS Interface and test set on at the same time, or turn the PCS Interface on before turning on the test set.

IMPORTANT!

The PCS Interface is disabled if test set power is cycled or if the PRESET key is pressed. To enable the use of the interface, you must set the PCS Mode field in the CONFIGURE screen to On.

The Analog Registration program listing contains an example of how to automatically detect the presence of the PCS interface and enable it if present.

If you are using the PCS Interface and cannot get the mobile to find a control channel or make any measurements, make sure you have enabled the interface before trying to find another cause.

Set to On to use the PCS Interface.

Compensating for Temperature Changes in the Interface

Operation varies over time as the interface warms up. To compensate for the change, select the Temperature field on the DCCH CALL CONFIGURE II screen after the interface has been on for 30 minutes. If the temperature has changed enough to require compensation, the interface will begin a compensation routine that lasts several seconds (you will hear the interface making several clicking sounds during the procedure). If compensation is not needed, the interface will not start the compensation routine.

You can query the need to compensate first (optional), or just issue the compensation command periodically. Compensation occurs only if needed after issuing the command:

SERV:LATCH:SEL ’pcs_temp_comp_status’ !Select compensation status latch. SERV:LATCH:VAL? !Query latch value. Returns 1 if needed, 0 if not needed. CALLP:DCCH:PCS:TEMP:COMP !Start the compensation process.

Connections

All of the tests described in this document use a single connection from the mobile’s antenna connector (or test port) to the RF IN/OUT port on the Test Set or PCS Interface. No separate audio connections are used.

Analog Registration

Description

This function causes the mobile station to “register” with the test set. This function causes the phone to send data such as Mobile Identification Number, Electronic Serial Number, and phone type (Station Class Mark).

Simulating this with the test set requires placing the test set into an analog “active” mode to simulate an active analog cell site. When the phone locks onto the test set and indicates service, the registration function is selected on the test set. The test set sends a series of alternating registration messages over the air until the mobile phone detects the messages and responds. The test set then decodes and displays the registration data sent from the mobile.

Test Conditions

• CALL CONTROL screen

•System Type = DCCH

• Control Channel = Analog, Channel Number 321

• RF Amplitude = −50 dBm (default)
