2 Making Measurements 2-1
Making Measurements Using This Chapter Using This Chapter Use this chapter to obtain an overview of how to operate the Agilent 8922M/S GSM Test Sets. This chapter is divided into the following sections: • • Making Measurements • Agilent 8922M/S Operating Modes - explains how to configure the Agilent 8922M/S so that measurements can be made. • Measurements - details how to perform the many different measurements available on the Agilent 8922M/S.
Making Measurements Agilent Technologies 8922M/S Operating Modes Agilent Technologies 8922M/S Operating Modes This section details the procedures necessary to control the Agilent 8922M/S and GSM mobile phone in each of the main operating modes. It is recommended that you read this section before attempting the “Measurements” section.
Making Measurements Agilent Technologies 8922M/S Operating Modes To configure the Agilent 8922M/S to the desired operating mode, carry out the following instructions, referring to Figure 2-1 on page 4 for the position of the fields. • NOTE Ensure (1) is set to mobile phone type you require (GSM900, E-GSM, DCS1800, or PCS1900). For use with DCS1800 or PCS1900, refer to the HP/Agilent 83220A/E Users Guide which explains how to configure the Agilent 8922M/S to test other mobile phone formats.
Making Measurements ACTIVE CELL ACTIVE CELL This is the default mode after cycling the power or selecting PRESET . A functional mobile phone will lock on (camp on) to a signal which is produced by the Agilent 8922M/S. The characteristic of this signal appears in the BASE STATION fields, (1), see Figure 2-2 on page 2-6. These fields show the Channel number and the Amplitude of the signal.
Making Measurements ACTIVE CELL 3 2 3 4 6 5 Figure 2-2 Active Cell Mode Making a Call From To call (or page) the mobile phone from the Agilent 8922M/S, it is necessary for the the Agilent 8922M/S Agilent 8922M/S to know the number of the SIM in the mobile phone. [This number to the Mobile Phone is the International Mobile Subscriber Identity (IMSI). This and other information is stored on the SIM card.] NOTE The Network number cannot be used to make a call.
Making Measurements ACTIVE CELL Press the following keys to do this: • • • SHIFT , CELL CONFIG (MS INFO) Move the cursor to the Paging IMSI field and enter the IMSI using the numeric data entry keypad. CELL CNTL , ORG CALL Performing a “location update” from the MS INFO screen allows the Agilent 8922M/S to update the IMSI. This can be done by either: • changing the Current location parameters and waiting for the mobile phone to re-camp. • setting IMSI Attach/Detach to On before powering on the phone.
Making Measurements ACTIVE CELL There may be many reasons for the measured level not being close to the expected level. The two most likely are that, either, the mobile phone is not operating correctly, or, there is some power loss between the Agilent 8922M/S RF IN/OUT connector and the mobile phone. If you suspect it is the second case, you can compensate the Agilent 8922M/S generator settings and measurement results for external losses or gains.
Making Measurements TEST MODE TEST MODE To enter this mode, select TEST MODE as described in the section titled “Agilent 8922M/S Operating Modes”. In TEST MODE, the Agilent 8922M/S no longer controls the mobile phone. The TEST MODE is used when it is not desired, or not possible, to set up a call between the Agilent 8922M/S and the mobile phone. The MOBILE PHONE area available in Active Cell controls three functions simultaneously: • • • The traffic channel transmitted by the Agilent 8922M/S.
Making Measurements TEST MODE NOTE While the Test Mode is selected, the three MEASURE ON parameters are also available on the bottom right-hand side of all measurement screens. This provides control of the Expected Input parameters during measurements. 4 1 2 3 Figure 2-3 Test Mode Mobile Phone To measure an incoming signal from the mobile phone’s transmitter, perform the Transmitter Testing following steps: Using Test Mode • Select TEST MODE.
Making Measurements TEST MODE Code is not known, it can be determined and corrected from measurements described later. Refer to the “Advanced Features” section mentioned later in this chapter. NOTE In the Active Cell mode, the Colour Code is automatically set. Once these have been selected, the Agilent 8922M/S is ready to measure incoming signals of the type specified. The mobile phone should be set up to generate a corresponding test signal to the one expected.
Making Measurements CW GENERATOR CW GENERATOR To enter this mode, select CW GENERATOR as described in the section titled “Agilent 8922M/S Operating Modes”. The CW Generator mode has the same measurement capabilities as the Test Mode but replaces the GSM BCH and forced TCH signals with a single unmodulated RF carrier. The frequency and amplitude of the Continuous Wave (CW) signal is controlled by the Channel, Amplitude, and the Frequency fields (1).
Making Measurements Measurements Measurements The measurements available on the Agilent 8922M/S can all be accessed from the cell control screen by selecting a measurement field under MEASUREMENTS, (see Figure 2-5 on page 2-13) and pushing the knob. GSM Specific Measurements The measurements available are: Ancillary Measurements You can also use the toolkit capabilities of the Agilent 8922M/S.
Making Measurements Measurements After making one type of measurement, another can be made by simply pressing CELL CNTL and, using the knob, selecting the next measurement of your choice. Peak Carrier Power The peak transmitter carrier power averages the transmitter carrier power for a Measurement single burst. This average is calculated over the time that the data information bits are transmitted.
Making Measurements Measurements Phase and Frequency Error Measurement Phase error and frequency error are measures of the modulation and noise performance of the radio’s transmitter path. Method Select the PHASE FRQ field on the cell control screen to access the phase and frequency measurements. NOTE The test is run automatically when the screen is selected. The measurement fields in this screen are RMS Phase Error, Peak Phase Error and Frequency Error (1), see Figure 2-7 on page 2-15.
Making Measurements Measurements These are: • • Power Ramp Mask Measurements PHASE ERR - this displays the phase error graphically. The phase error trace is displayed using an autoscaling phase error axis versus data bits (numbered 0 through 147). DATA BITS - this screen allows you display a screen which details the values of the 148 bits in the timeslot (including midamble). If a known test signal is being used, the reception of these bits can be verified.
Making Measurements Measurements The power ramp measurements are divided into three screens where you can view different parts of the signal and one screen which displays a series of amplitude values at various times during the burst. These screens can be revealed by highlighting and selecting from the View field (2): • • • • Rise Edge - displays the top 30 dB of the rising section of the waveform.
Making Measurements Measurements Pulse Measurements If you have option 006 (spectrum analyzer) installed, you can make measurements (Available if Option on the lower portion of the pulse. These measurements can be accessed from the 006, Spectrum Power Ramp screens.
Making Measurements Measurements Bit Error Rate Measurement The Bit Error Rate measurement allows you to test the sensitivity of the mobile phone’s receiver. By reducing the signal transmitted by the Agilent 8922M/S, you can test the ability of the receiver to accurately decode its incoming signal. Data bits that are decoded are sent back to the Agilent 8922M/S. The Agilent 8922M/S compares them to original signal that was sent out and the differences are derived from this.
Making Measurements Measurements By varying the Base station Amplitude field (4), you can test the mobile phone’s receiver sensitivity. Actual results can be compared with the values reported by the radio. NOTE If the Base Station amplitude is lowered too much, the radio will lose the call. This will need to be re-established by increasing the base station amplitude, returning to the cell control screen, and originating the call before you can continue measurements.
Making Measurements Measurements This sets the reference level to which the offset frequency values are compared. • • Select Ramping or Modulation (3). Set your Freq Offset value (4). 5 2,3 Figure 2-11 Output RF Spectrum Measurements • Output RF Spectrum Measurements Using a 3-Pole Synchronously Tuned Measurement Filter 1,4 The trace of the output RF spectrum can be viewed if you highlight View and select Trace (5). GSM Recommendation 11.10 and 11.
Making Measurements Measurements In the Agilent 8922, Output RF Spectrum measurements are made using a 3-pole synchronously tuned measurement filter. The measurement results will differ from measurements using a 5-pole filter. The difference between measurements of the “ideal” signals using a 3-pole filter and a 5-pole filter are shown in Table 1 and Table 2.
Making Measurements Measurements Table 3 Table 4 Adjusted Limits Based on 3-Pole Filter Output RF Spectrum Due to Modulation Power Control Level Offset from Carrier (kHZ) 0 100 200 250 400 600 to 1800 0 (43 dBm) 0 dB 0.5 dB -27.5 dB -32 dB -51 dB -70 dB 0 (39 dBm) 0 0.5 -27.5 -32 -51 -66 0 (37 dBm) 0 0.5 -27.5 -32 -51 -64 ≥5 (≤ 33 dBm) 0 0.5 -27.
Making Measurements Measurements Spectrum Analyzer (Available if Option 006, Spectrum Analyzer, is Fitted) The spectrum analyzer allows you to view the mobile phone’s signal over a wide dynamic range. It also allows you to view any adjacent interference which may exist. NOTE The spectrum analyzer can detect very low power signals where Active Cell and even Test Mode cannot operate. Broken cable or connectors can be found using this function. Method Select SPEC ANL in the cell control screen.
Making Measurements Measurements NOTE The RF Generator and spectrum analyzer can be tuned to different frequencies allowing the inspection of the IF signals inside the mobile phone. 1 2 Figure 2-12 3 Spectrum Analyzer Measurement Use the MeasReset (2) to reset the trace and measurements in the Agilent 8922M/ S. This is useful if you are using the Max Hold field (3). The resolution bandwidth of the spectrum analyzer is automatically coupled to the frequency span.
Making Measurements Measurements Scope The oscilloscope function of the Agilent 8922M/S allows you to view the demodulated signal from the mobile phone. This can be used for fault-finding in the audio path. Select SCOPE in the cell control screen to gain access to the oscilloscope function of the Agilent 8922M/S. Selecting (1), see Figure 2-13 on page 2-26, gives access to other functions of the oscilloscope.
Making Measurements Measurements Audio The audio function measures the audio frequency and voltage of the demodulated signal from the mobile phone or from a number of other sources selectable using AF Anl In (5), see Figure 2-14 on page 2-27. Select AUDIO in the cell control screen to gain access to the audio function of the Agilent 8922M/S. The measurements of the audio voltage and frequency commence within a short time of the screen being accessed.
Making Measurements Measurements CW Measurement The CW Measurement screen displays the carrier frequency and power of a continuous (non-pulsed) signal. The CW Power measurement offers a greater dynamic range than is available when making pulsed measurements. CW Power is a broadband measurement. The CW Frequency measurement is obtained using a tuned, selective input. The RF analyzer should be set to within 500 kHz of the expected signal frequency.
Making Measurements Measurements NOTE Although CW Measurements is a broadband measurement, it uses calibration data that relies on the expected input frequency being set correctly. The Power Detector is connected so that it will only make measurements on signals present at the RF In/ Out port.
Making Measurements If You Have Problems with a Measurement If You Have Problems with a Measurement This section tells you what to do if either of the following screen display events occurs: • Message Line Messages (on the top of the screen). • • • Is a Message Line displayed at the top of the screen. Possible Solutions to Message Line Errors. Sync Status Messages • Is an Error Message Displayed in the Sync Status Field. Refer to Chapter 7, “Messages”, for more information.

Making Measurements If You Have Problems with a Measurement Possible Solutions to Solution 1 - Trigger Timing Sync Status Errors Check if the trigger is being received. On the MEAS SYNC screen (press MEAS SYNC to gain access), check if the correct burst type has been defined. On the Data Bits screen: A The First Bit field on the Phase Freq:Data Bits screen displays the time difference between when a trigger is being received and when the first bit of a burst occurred (A).
Making Measurements If You Have Problems with a Measurement Solution 2 - Midamble Sync On the MEAS SYNC screen (press MEAS SYNC to gain access), • Check the definition of the signal’s burst type (A). • Check the Burst Sel field (B). A B Check the bit pattern of your measurement Perform a Data Bits measurement (D). An “M” will display under the bits that are identified as the midamble bits.
Making Measurements If You Have Problems with a Measurement Solution 3 - Level Check the following fields on the RF Generator/RF Analyzer screen (press SHIFT , CELL CNTL , (RFG/RFA) to gain access). 3 Pulse field (a), (if signal is pulsed) Ext or Hop Trig should be selected. 4 Amplitude field (b), for the expected amplitude 5 Frequency field (c), for the correct frequency. 6 RF Input field (d), for the correct connector choice. 7 AGC Mode field (e).
Making Measurements If You Have Problems with a Measurement Solution 4 - Amplitude Envelope • Check if the Pulse Amplitude is ± 1 dB of the expected value during the useful part of the burst. If FM Errors: Perform a Phase Freq:Data Bits measurement. Dashes (a) will display under the bits where the power is too low. If No FM Errors: Perform pulse demodulation measurements. Connect PULSE (DEMODULATION OUT) connector to SCOPE IN (MEASURE) connector on the front panel.
Making Measurements Advanced Features Advanced Features Other Screens The screens mentioned in this section are not necessary for simple measurement of mobile phones as the work is done by the functions mentioned previously. However, the advanced user may find it worthwhile to know what these screens are and what they are capable of doing. • RF Generator/RF Analyzer - this screen controls the Agilent 8922M/S RF generator and RF analyzer.
Making Measurements Advanced Features • Using RF Rise Triggering SMS Cell Broadcast - the SMS CB screen allows you to test whether the mobile phone is capable of correctly receiving and displaying a message sent from a base station using the Short Message Service (SMS) Cell Broadcast protocol. This screen can be accessed by highlighting the More field in any main screen and selecting SMS CB.
Making Measurements Advanced Features Power Ramp Setting The mobile transmitter output ramp should settle so that it complies with the power Time mask (GSM Rec 11.10) by the time output level calibration is done in the manufacturing process. The power mask is displayed in the Power Ramp screens. Peak Carrier Power measurement method is not made to GSM Rec. 11.10. If you need to make a measurement to this specification, go to the Power Ramp Summary screen.
Making Measurements Advanced Features The beginning of the 0 sample bin will be between 0 and 75µS (bit 0 - 20) after the trigger as the sampler runs asynchronously to the trigger. The last sample bin will complete sampling between 450µS and 525µS (bit 121 - 142) into the burst. The measurement processor discards the 0 sample bin. This effectively removes the ramp-up overshoot. Each measurement is also RF Power Qualified to ensure only valid bursts are measured.
Making Measurements Advanced Features NOTE The GPIB requires the use of base 10 values, 432h = 1074d, for example: SERV:LATCH:VAL 1074. 2 The value entered is relative to the beginning of the zero bit of the zero slot on the downlink baseband. A 4.7 bit modulator delay occurs between the baseband and the RF domain which must also be taken into account. Since the value may only be integer, round to the nearest whole value. The following timing error is introduced due to 156/157 bit timing.
Making Measurements Advanced Features Unexpected Operations NOTE These are descriptions of operations which may be unclear to the user as to how they occurred. These are NOT defects. 1 The Agilent 8922M/S occasionally sends ABORTS to the attached protocol monitor. These ABORTS are normal and logging data is not lost. 2 In the FA and SD/4+FA control channel configurations, the Agilent 8922M/S sends speech frames rather than fill frames on the FACCH when there is nothing else to send.
Making Measurements Advanced Features 9 The RF Generator may become uncalibrated in a hopping situation when the last CW frequency setting was outside the GSM or DCS band. If you are using the RF Generator outside the normal GSM or DCS bands, make sure you set a valid GSM or DCS frequency in the CW frequency before entering a hopping mode. This includes the ACTIVE CELL (ACTIVATED state on the CELL CONFIG 2 screen) on the Agilent 8922M/S.
Making Measurements Advanced Features 12 Some measurement results may be displayed as ---- due, for example, to mobile failure. The measurement has been armed but has not completed. In these circumstances a GPIB query of the measurement will not return a result. This event should be catered for by adding a time-out to the query and a “CLEAR” operation as described in paragraph 11, above. 13 When changing between screens, the DSP results may briefly show a very large number. This is expected behavior.

(Refer to ‘Loading a Test Procedure” on page 8-11 for help.) 3 Select the Run Test field.
Instrument BASIC Memory Cards The Memory Card Battery A memory-card battery should last between 3 and 5 years depending on its use. Write the date a battery is installed in the memory card. The date is important for determining when to replace the battery. When the battery needs replacing, insert the card into the Agilent 8922M/S and turn the POWER switch on. An inserted memory card takes power from the Agilent 8922M/S preventing the card’s contents from being lost.
Instrument BASIC Programming and Using the TESTS Subsystem Programming and Using the TESTS Subsystem This section describes the concepts and tasks associated with the TESTS subsystem. It is intended to help the experienced programmer develop programs, or modify existing programs. TESTS Subsystem File Descriptions Three types of files are used in the TESTS subsystem to store different types of information. Code Files The first aspect of an automated definition is the code itself.
Instrument BASIC Programming and Using the TESTS Subsystem Figure 8-10 TESTS Subsystem File Relationship TESTS Subsystem Screens The TESTS subsystem uses several screens to create, select, and copy files, and to run tests. The Main TESTS Subsystem Screen Refer to Figure 8-11 on page 8-28. The Main TESTS screen is accessed by pressing the front panel TESTS key. Notice that the first line shows the currently selected Procedure. The associated Library is listed, as well as the location of the code.
Instrument BASIC Programming and Using the TESTS Subsystem Figure 8-11 The Main TESTS Subsystem Screen TESTS Subsystem User-Interface Screens The TESTS subsystem allows the user to easily modify the test subroutines, parameters, specifications and configuration to correspond to the requirements of a specific Radio. There are several user-interface screens that allow the user to do this.
Instrument BASIC Programming and Using the TESTS Subsystem IBASIC Programming IBASIC gives you control over the internal functionality of the Agilent 8922M/S, as well as control over any external instruments connected to the GPIB. Refer to the Agilent 8922M/S Agilent Instrument BASIC Programmer’s Guide for details about IBASIC. The manual contains important information about the IBASIC programming-language code, Test Procedure and Test Library file structures, and programming and interfacing techniques.
Instrument BASIC Programming and Using the TESTS Subsystem 1 2 3 5 Figure 8-12 4 Test Execution Conditions To Have Testing Stop or Continue on a UUT Failure Refer to item (1) in Figure 8-12 on page 8-30. On UUT Failure.….….…. Continue Testing continues whenever the UUT (Unit Under Test) fails to meet its test specification limits. When this occurs, an error is listed on the test-results printout and/or is displayed on the CRT. On UUT Failure.….
Instrument BASIC Programming and Using the TESTS Subsystem To Select Printing Conditions Refer to item (3) in Figure 8-12 on page 8-30. Output Results.….……All All test results are shown on the output device (CRT and/or printer). Printouts include a “banner” listing the test conditions, measured values, lower and upper limits, and whether the test passed or failed. The Comment field is shown at the top along with any identifying information from the Output Heading field. Date, and time is also output.
Instrument BASIC Programming and Using the TESTS Subsystem Using Autostart Ensure the Autostart field toggle is set to On (see Figure 8-13 on page 8-32 (1)); this allows the Agilent 8922M/S to go straight to the Procedure Menu each time the Agilent 8922M/S is switched on, providing a Memory Card is inserted in the front panel of the Agilent 8922M/S. If the Procedure Menu screen does not appear on the Agilent 8922M/S display, select TESTS and load the procedure.
Instrument BASIC Programming and Using the TESTS Subsystem 5 Select the Yes/No field and decide if the test is to be run on all channels (select Yes), or if the test is to be run on prime channels only (select No). (Prime channels are selected from the Edit Freq field.) Four factors determine how long it takes to test a radio: • • • • The number of tests selected in the sequence. The kind of tests that are selected. The order in which the tests are selected. The number of points measured in a test.
Instrument BASIC Programming and Using the TESTS Subsystem 3 Test Sequence as described below. When finished editing sequence select TESTS to return to test screen. a. Select either Edit Parm or Edit Spec from the test function field to continue editing. OR b.

Glossary ARFCN Absolute Radio Frequency Channel Number BCH The BCH (Broadcast Channel) is a beacon which is always turned on so that mobile can look out for it when trying to find service. A useful BCH always carries information in timeslot 0. The BCH ARFCN has to be active in all timeslots to allow mobiles to synchronize to other cells. There are a number of other areas to the BCH: • TCH (Frequency correction Channel) is a special burst on the BCH.
Glossary Burst-by-Burst Bit Error Rate The Burst-by-Burst Bit Error Measurement makes use of a new loopback path within the mobile to calculate the equivalent Class II BER. This measurement is 5 times faster than the conventional method. This is also sometimes known as Fast Bit Error Measurement. Channel Coding The baseband digital process used to arrange the error protected speech data into the final form necessary for RF transmission.
Glossary only uses one burst in 26. When the FACCH steals control from the TCH small drop-outs in the speech can often be heard. Frame A repetitive collection of time slots in a TDMA system. GMSK Gaussian Filtered Minimum Shift Keying. The type of digital modulation used for the GSM system. GSM900 Global System for Mobile Communication. GSM900 is the original GSM system, using frequencies in the 900 MHz band, and is designed for wide area cellular operation.
Glossary RPE-LTP Regular Pulse Excitation Long Term Prediction. A commonly used technique for converting voice from analog to digital form. This is the CODEC that is used by GSM, DCS1800 and PCS1900 systems. RSSI Received Signal Strength Indicator. Reception level. SACCH There is a spare frame every 12 TCH frames and this is used for the SACCH (Slow Associated Control Channel). On the downlink, the SACCH is used to send slowly but regularly changing control information to the mobile.
