Chapter 1, Calibrate the Test Set

CDMA Channel Level Calibration Procedure

Procedure Overview

The Test Set optimizes the level accuracy of CDMA code channels and the AWGN (Additive White Gaussian Noise) generator by measuring the analog I/Q signals using an internal DSP-based voltmeter. Level correction factors are generated by a ROM-based program named PCB_CAL and are applied to gain control DACs, which control the fine level adjustment in the amplitude scaling path.

Calibrated channel power provides accurate values for Eb/Nt, the ratio between Traffic channel power and AWGN. It is critical that these levels remain accurate. A level accuracy error of 0.8 dB could alter FER from 0.5% to 5%.

Calibration may take a minute or longer, depending o n the RF Channel Std and Alt Chn St d field settings. Average Power measurements are zeroed as part of the Channel Power calibration process.

Procedure Overview

Calibrating Channel Power measurements ensures that the Test Set achieves accurate low-level CDMA power measurements.

Channel Power measurements:

• indicate power in a 1.23 MHz bandwidth

• are performed at one of the Test Set’s IF frequencies by a DSP (Digital Signal Processor)

• use the Test Set’s average power detector to calibrate the relative levels measured at IF.

During this process, the message "Zeroing Average Power" will be displayed (for about 2 seconds).

If RF power was not lowered as shown in step 2, the Test Set will display "Zero degraded. Reduce generator level for best results."

Procedure Overview

This procedure establishes a 0 dBm reference for Average Power measurements. Average Power measurement mode is used on higher-level signals. Lower-level

power measurements are performed by the Test Set’s Channel Power measurement.

NOTE: A misleading Average Power measurement may appear when low (or no) signal power is

applied to the RF Input! When the RF generator’s output port selection is RF IN/OUT

some of the signal energy from the Test Set’s generator is detected by the Test Set’s broadband average power meter. This condition does not affect typical CDMA measurements for two reasons: 1) During Average Power measurements, CDMA generator levels are too low to introduce significant energy to the power detector. 2) When the generator level is high enough to introduce significant energ y to the power detector, the mobile station’s signal power should be within the range of Channel Power measurements. Channel power measurements are frequency-selective, an d do not detect significant energy from the Test Set’s generator, which is tuned 45 MHz away from the analyzer.

Correcting for RF Path Loss

Procedure Overview

Using the RF Level Offset feature of the Test Set corrects for RF path power losses that occur in cabling and connectors between the Test Set and a mobile station.

It is highly recommended that RF path loss is corrected for. Besides returning power measurements that do not have to be adjusted to account for RF path loss, the Test Set uses t he val u es you enter in this procedur e to adjust the ana lyz er path attenuation to an optimum value for demodulation and measurement functions.

NOTE: The settings you made in this procedure must be re-entered after a power-cycle or

instrument preset.

Chapter 2, Set Up a Call

Setting Up a CDMA Call

When you test a CDMA or dual-mode (CDMA and analog) mobile station you should first attempt to set up a CDMA call. Once a CDMA call is connected, mobile station transmitter power measurements are displayed and many other

CDMA measurements are available when by selecting the Test Set’s CDMA screens.

If the mobile station has dual-mode capability, the CDMA call can be handed off to analog operation at the press of a knob. With the mobile station operating in analog mode, fundamental audio and RF transceiver measurements are provided on one screen.

NOTE: If the mobile station being tested is not able to make a call, analog transceiver

measurements can be made using the Test Set’s general-purpose measurement capability. Refer to the ANALOG MEAS, SPECTRUM ANALYZER (Opt 012 only), and OSCILLOSCOPE screen descriptions in the HP 8924E User’s Guide

Requirements:

Before you start this procedure, make sure you have the following items or information , or meet the following cond itions.

❒ Isolation or shielding apparatus for the mobile station if significant signal interference is

present.

❒ Hardware (cables, adapters, and so forth) to ma ke the RF connection from the Test Set’s

front-panel type N connector to the mobile station (cabling should be as low-loss as possible).

❒ Knowledge of the CDMA RF channel that mobile station is programmed to find service

on.

❒ Knowledge of the CDMA protocol and RF channel standard used by mobile station. ❒ A power supply with dc-power cabling to the mobile station or a battery that has

sufficient charge to power the mobile station for the duration of testing.

❒ (Optional) If you want to make analog audio measurements, a way to make audio

connections (microphone and ear) from the mobile station to the Test Set’s audio BNC front-panel connectors.

NOTE: Mobile stations operating in the PCS frequency band (1900 MHz) can be tested only on

HP 8924E Test Set’s that are configured with the HP 83236 PCS Interface. This interface attaches to the bottom of the HP 8924E inside of a “shell” called the Ben c h Top Kit.

3. Enter the mobile station’s preferred system identification.

4. Press the PREV key to return to the CDMA CALL CONTROL screen.

System ID is programmed into the mobile station by the service providers. When power is turned on, the mobile station searches for CDMA signals. When the CDMA signal is demodulated, the mobile station

finds out whether or no t the Test Set’s system matches the system it is programmed to prefer service on.

Depending on how the mobile station is programmed, entering an incorrect number in this field could cause the mobile station to delay any call-p rocessi ng until it has exhau sted a search of other RF channels , or it may not allow any calls at all.

5. Make the RF connection between the Test Set and the mobile station.

Setting up a Call

Make sure all connections to the mobile station, including dc power, are made.

Some mobile station’s do not have an RF connection. In these cases, the manufacturer will usually make a fixture, such as a car adapter, that will provide an RF cable connection. The mobile station snaps into the fixture and an RF connection is made through an electromagnetic coupler near the mobile station’s antenna.

6. Turn on power to the mobile station.

Wait until the mobile station has found digital (CDMA) service (this should take no longer than about 30 seconds).

If the mobile station does not find digital service, refer to the

Checklist" on page 52

Most mobile stations have a NO SERVICE annunciator that will go out when the mobile station has found service. Other mobile stations use an LED that indicates when service has been found.

"Problem Solving

(igital)

If a strong signal from an analog base station is present, or the mobile station is programmed to prefer analog service, the mobile station may not find digital service. If this condition exists, re-program the phone, or isolate it from the competing analog signal using an RF isolation chamber.

Caution: Do not exceed 6 W continuous power into the Test Set’s RF IN/OUT connector with any transmitter.

7. Dial 1234 on the mobile station’s handset, then press SEND.

You can use practically any sequence of numbers to perform this step. 1,2,3 was chosen simply for convenience.

The Test Set’s Access Probe annunciator will light, indicating that the mobile station sent an access probe sequence, then the Connected annunciator will light.

After a mobile station has successfully originated a call, you will see the mobile station’s identification displayed in the MS Database field.

Another way to retrieve MS Database data from the mobile station is by selecting the Register fiel d b e fore a call is connected.

8. Speak into the mobile station’s microphone.

Your voice will be echoed back wi th a 2 second delay.

H e l l o

This test is referred to as “Voice Echo” and is performed with the mobile station connected on a Service Option 1 or Service Option 32768 call.

Voice Echo is a subjective test of the mobile station’s ability to encode your voice, modulate the carrier with the information data representin g your voice, and demodulate/decode the same voice information, then outp utting an audio reproduction of you voice on the earpiece of the mobile station.

Procedure Overview

Many mobile station tests performed by the Test Set require that a call be connected. To set up a call, the Test Set must be configured to include:

❒ The mobile station’s CDMA RF Channel ❒ The mobile station’s Protocol ❒ The mobile station’s RF Channel Standard ❒ The mobile station’s system identification (unless mobile station roams).

The steps beginning on page 42 describe how to make a mobile st at ion originated call (by dialing number s on the mobil e station). The mobile stat ion regis ters as the call is being connected, but there are other circumstances that can cause mobile station registration. They are:

Chapter 2, Set Up a Call

Procedure Overview

• Power-up registration (usually initiated when mobile station is turned on) and

• Zone-based registration (initiated by selecting the field labeled Register)

Regardless of which event causes the mobile station to register, the field labeled

MS Database displays the mobile stati on’s identif ication. As soon as you see this

field updated, you have the option of making a base station originated call by pressing the CALL key on the Test Set’s front panel.

Chapter 2

Chapter 2, Set Up a Call

Problem Solving Checklist

If the mobile station does not find service, does not register, or does not connect when a number is dialed on it, check the following items:

❒ Is the RF cable connected? ❒ Is the RF Channel number correct? (Set the RF Channel on the CDMA Call Control

screen.)

❒ Is Sector A Power adequate? If interference f rom other cellul ar band signal s is present,

Sector A Power may need to be set to a level greater than the instrument’s preset value of −75 dBm/BW. (Set Sector A Power on the CDMA Call Co ntrol screen.) Example: If the mobile station is finding analog service, adjust Sector A Power to −30 dBm/BW, then cycle power on the mobile station. Isolating the mobile station may be necessary.

❒ Is the AWGN generator (CDMA Gen Control screen) off? ❒ Is the mobile station programmed to roam? If not, set the System ID on the CDMA Cell

Site Configuration screen, then cycle power on the phone.

❒ Are the entries in the Rgstr SID and Rgstr NID fields valid entries for the mobile

station? (The Rgstr SID and Rgstr NID field entries, found on the CDMA Cell Site Configuration screen, must be recognized as a valid SID/NID pair by the mobile station).

❒ Are the entries in the Rgstr SID and Rgstr NID fields different than the mobile station’s

Home SID/NID? (The Rgstr SID and Rgstr NID fields, found on the CDMA Cell Site Configuration screen, must be d ifferent than the mobile station’s Home SID/NID).

❒ Is the power s upply providing ad equate current? (Make s ure the mobile statio n’s power

supply duplicates the voltage, impedance, and ampere hours of the manufacturer’s recommended power supply).

Chapter 3, Mobile Station CDMA Tests

Rho (Transmitter Waveform Quality)

Measurement Overview

The value you obtained during the Rho measurement is based on a compar ison, or cross-correlat ion, of the actual transmitted signal to the ideal signal transmitting the same data. Rho represents the percentage of power in the transmitted signal that correlates with the ideal signal.

Rho measurements give you a very comprehensive indication of transmitter

performance. If there are significant problems with the mobile station’s output power amplifier, I/Q modulator, or filters there is a good chance they will cause degradation in the Rho measurement value.

When a Rho measurement is made, the following measurements are also made:

• Frequency Error (see table 1).

• Phase Error (excessive values may be due to filter ripple, I/Q modulator quadrature errors, or distortion or compression in output power amplifier).

• Amplitude Error (excessive v alues may indica t e distortion or compression in out put power amplifier).

• Time Offset (see table 1).

• Carrier Feedthrough (values higher than −25 dB indicate excessive I/Q modulator DC offsets)

• Average Power and Channel Power

Measurement Overview

During this test, FER is measured with the AWGN (Additive White Gaussian Noise) generator turned on. The relative settings of AWGN, Sector Power, and Traffic, along with Data Rate provide a value called E signal-to-noise ratio in analog radio test.

Test standards require FER testing at various levels of E using the Data Rate and Traffic fields. The value you enter in the FER Spec field provides Pass/Fail criteria for the test, which will be more stringent at higher values of E

Because the Test Set supports the Confidence Interval FER, the number of frames tested will typically be far less than the number of frames entered in the Max F rames field. T his speeds up F ER tests dramatically.

Performing a CDMA to Analog Handoff

The HP 8924E has the capability t o simulate both a CDMA cell site and an anal og cell site. This makes it possible to perform a handoff from a CDMA traffic channel to an analog voice channel. This type of handoff allows you to easily change from CDMA testing to analog testing.

The following conditions are required for a successful handoff:

❒ You must know the mobile station’s system type (AMPS, NAMPS). ❒ A CDMA call must be connected. ❒ The mobile station must be programmed to allow analog operation.

For some of the following analog tests, you will need audio connections from the

mobile station’s microphone and earpiece to the Test Set’s AUDIO OUT and AUDIO IN, respectively.

Chapter 4, Mobile Station Analog Tests

Chapter 4, Mobile Station Analog Tests

Receiver Audio Distortion and Hum and Noise (requires audio connections)

Measurement Overview

Receiver Audio Harmonic Distortion is measured with the Test Set providing an

FM signal to the mobile station, modulated by a test tone from the Test Set’s audio frequency generator. (A SAT tone is also present on the RF signal). To measure distortion, the audio signal from the mobile station’s earpiece (receiver output) is cabled to the Test Set’s AUDIO IN connector. The Test Set’s audio analyzer measures th e level of the audio output, then notches out the test to ne a nd measures only the RMS harmonic content produced by the audio signal. Distortion is then displayed as the percentage of mobile station receiver output level that was due to the harmonic content.

Typically, Audio Harmonic Distortion should be less than 5%. Receiver hum and noise uses essentially the same setup as distortion, except that

the modulation source is turned off, and residual FM is measured. The hum and noise measurement is the ratio of AC leve l from the mobile station’s receiver without modulation to AC level with modulation.

Typically transmitter Hum and Noise should be at least 32 dB below levels with modulation on.

SINAD, a measure of receiver sensitivity, also uses essentially the same setup as distortion, except the RF amplitude to the mobile station’s antenna input is lowered until 12 dB SINAD is rea che d.

7. Make the transmitter hum and noise measurement.

1. Position the cursor in front of the audio frequency generator level field as sh own. Press the ON/OFF key.

The Lo and Hi limit annunciators should be

flashing.

The FM Deviation field will display the FM hum

and noise level. It should be at least 32 dB lower than the reference level.

Setting the 0 dB reference allowed the Test Set to display the ratio of FM without modulation (residual FM) to FM with the test signal applied, in the FM Deviation field.

Measurement Overview

Transmitter D istortion (and Noise) is measured with a test tone adju sted to

frequency modulate the mobile station’s transmitter with a specified deviation. The FM signal from the mobile station’s transmitter is demodulated by the Test Set using a C-message weighted filter, and distortion and noise are measured.

Typically, distortion should be less than 5%. Transmitter Hum and Noise is measured by modulating the mobile station’s

transmitter with a test tone adjusted to produce a specified amount of deviation. With the signal from the mobile station’s transmitter demodulated by the Test Set using a C-message weighted filter, the amount of deviation is recorded. To determine the hum and noise, which is caused by residual FM, the modulation is removed and the ratio of residual FM to FM with the test signal on is calculated.

Typically, FM Hum and Noise should be less than

−32 dB.

Short Message Service Tests

Short Message Service Tests

The following SMS tests verify that the Mobile Station Under Test (Mobile Station) is capable of receiving short messages.

Short messages can be sent:

• on the Paging/Access channels (phone has registered but is not on a traffic channel)

• on the Traffic channels (Service Option 6 or 14)

• on the Traffic channels (Service Option 1 or 32768)

All SMS procedures performed by the Test Set are mobile station terminated, meaning that the Test Set is sending messages to the Mobile Station.

The short message feature for the Mobile Station must be activated to perform these tests.
