Precautions

On safety
As the laser beam used in the CD player section is harmful to the eyes, do not attempt to disassemble the casing. Refer servicing to qualified personnel only. Should any solid object or liquid fall into the player, unplug the player, and have it checked by qualified personnel before operating it any further.

On operation

If the player is brought directly from a cold to a warm location, or is placed in a very damp room, moisture may condense on the lenses inside the CD player section. Should this occur, the player will not operate properly. In this case, remove the CD and wait about an hour for the moisture to evaporate. If the player has not been used for a long time, set it in the playback mode to warm it up for a few minutes before inserting a cassette. If you have any questions or problems concerning your player, please consult your nearest Sony dealer.

Troubleshooting

General The power does not come on. Connect the mains lead securely. Make sure the batteries are inserted correctly. Replace all the batteries with new ones if they are weak. You cannot turn on the player with the remote when you operate the player on batteries (CFD-S32/ S32L only). The power is not on, and "bAttErY" and "Error" are displayed alternately. Make sure the batteries are inserted correctly. Replace all the batteries with new ones if they are weak. There is no audio. Make sure the function you want to use appears in the display. Adjust the volume. Unplug the headphones when listening through speakers. Noise is heard. Someone is using a portable telephone or other equipment that emits radio waves near the player. tMove the portable telephone, etc., away from the player. CD Player The CD does not play or no dISC lights in the display even when a CD is in place. Make sure that the CD compartment is closed. Place the CD with the label surface up. Clean the CD. Take out the CD and leave the CD compartment open for about an hour to dry moisture condensation. Make sure "Cd" appears in the display. The sound drops out. Reduce the volume. Clean the CD, or replace it if the CD is badly damaged. Place the player in a location free from vibration. Clean the lens with a commercially available blower. The sound may drop out or noise may be heard if the CD is recorded using a personal computer(CD-R,etc.). Radio The audio is weak or has poor quality. Replace all the batteries with new ones if they are weak. Move the player away from the TV. The picture of your TV becomes unstable. If you are listening to an FM program near the TV with an indoor antenna, move the player away from the TV.
Tape Player The tape does not move when you press an operation button. Close the cassette compartment securely. The REC z button does not function or the tape does not play or record. Make sure the safety tab on the cassette is in place. Make sure "TAPE" appears in the display. Poor or distorted playback, recording or erasing quality. Clean the heads, pinch roller and capstan with a cleaning swab slightly moistened with cleaning fluid or alcohol. Replace all the batteries with new ones if they are weak. TYPE II (high position) or TYPE IV (metal) tape is being used. Use TYPE I (normal) tape only. Demagnetize the heads using a commercially available tape head demagnetizer.

2.3 Signals

A number of RF and audio signals were used during the NRSC testing. For convenience, these are listed and described below.

2.3.1 RF Waveforms

For all testing, the desired carrier was placed at 1.00 MHz, and the interfering station placed at 10 kHz offsets therefrom. Each carrier was modulated with one of the audio waveforms listed in Section 2.3.2, according to the test being performed. When a hybrid RF signal was required, DAB was enabled on the exciters front panel. This activated the DAB carriers, which were added to the analog modulated waveform by the exciter. With DAB off, the peak positive modulation was not allowed to exceed +125%, and the peak negative modulation was not allowed to exceed 100% (pinchoff). Because all of the modulating audio was known beforehand, the appropriate scaling for the analog audio to achieve the desired modulation was determined directly. Attachment C describes this procedure in detail. The resultant modulation percentage was verified daily using a modulation monitor. In addition, the spectral containment of the modulated carrier with various modulation was investigated to insure that there were no significant out-of-band emissions.
2.3.2 Baseband (audio) Waveforms
Full Scale 1kHz Tone: This track consists of a stereo, unprocessed 1 kHz sinusoid, 30 seconds in duration, which utilizes the entire dynamic range of the CD player. The tone was generated using the MATLAB code below, and subsequently written to CD in stereo 16 bit, 44.1 kHz audio format. fs=44100; a=cos(2*pi*1000*[0:1/fs:30]')*[1 1]; wavwrite(a,fs,'fullscale1khz.wav'); Silence: The silence track is a thirty second track of all zeros; that is, silence with no DC offset. The file was generated using the code below (which follows that above). The silence was then written to CD in stereo 16 bit, 44.1 kHz audio format. a=a*0; wavwrite(a,fs,'silence.wav');

For both the desired and undesired pre-processing, the unprocessed audio was played using DENON CD player #2, and the AES/EBU signal passed through the Optimod 9200, which was configured as follows: Voice cuts: Processing: Preset: News HF Curve: NRSC Setup: INPUT: Digital POS PEAK: 125% BANDWIDTH: HP FLTR: 50 Hz LP FLTR NRSC or 4.5 kHz Digital Input: DI MODE: DIG-L DI REV VU: -11.0 dBFS DI REF PPM: -3.0 dBFS Digital Output: DO 100%: -3.6 dBFS DO RATE: 44.1 kHz DO SYNC: Internal HF DELAY: Off HF Shelf: off Digital Input: DI MODE: DIG-L DI REV VU: -11.0 dBFS DI REF PPM: -3.0 dBFS Digital Output: DO 100%: -3.6 dBFS DO RATE: 44.1 kHz DO SYNC: Internal HF DELAY: Off HF Shelf: off Digital Input: DI MODE: DIG-L DI REV VU: -11.0 dBFS DI REF PPM: -3.0 dBFS Digital Output: DO 100%: -3.6 dBFS DO RATE: 44.1 kHz DO SYNC: Internal HF DELAY: Off HF Shelf: off

The AES/EBU outputs of the Orban were connected to the Digital Input of the LynxOne audio card for recordings. Cooledit Pro was used to perform the recordings. Once the processed recordings were completed, they were each cropped to the section of interest. These cropped files were then written to CD in stereo 16 bit, 44.1 kHz format for use in the subjective testing.

3. Test Procedures

3.1 Common Test Procedures
Several procedures are used repeatedly in both the calibration and testing procedures. For convenience, these detailed procedures are listed once in this section, and referenced by name or section thereafter.
3.1.1 RF Power Measurements
This test procedure is used to measure RF power level of one exciter at the end of the RF signal chain, just prior to the receiver. The test is performed using the HP 437B power meter and the HP 8482A power sensor, configured as described in Section 2.2.2, Equipment Settings. 1. Before connecting an RF signal to the input of the power sensor, press the ZERO button on the power meter to zero the unit prior to taking a measurement. 2. Disconnect Splitter #2 from the cable leading to the BNC bulkhead, and terminate this tap with a 50 terminator. 3. Disconnect the second exciters cable from Splitter #1. Terminate both the unused tap on Splitter #1 and the disconnected cable with 50 terminators. 4. Turn off the DAB carriers of the exciter, if necessary. Stop or pause any program material playing on the corresponding CD player. This will result in an unmodulated analog carrier. 5. Using cable 36-1DS, connect Splitter #2 to the power sensor. Read the power measurement to the nearest hundredth of a dB.
3.1.2 Audio SNR Measurements
Measurement of audio SNR can be performed with either of two measurement devices: the AP System II Cascade, or the HP Audio Analyzer. For the objective testing, the AP System II was used; for the subjective testing, the HP was used. Measurement of Audio SNR using the System II Cascade: 1. Cue and play the Full Scale 1kHz Tone track on the appropriate CD player. When making SNR measurements with an interferer present, simultaneously cue and play the appropriate processed pink noise track on CD player #2. 2. After 5 seconds, click on the Go button in the Sweep panel to start taking signal level measurement data. The Data Editor panel will display the recorded signal level measurements, and when the sweep is done it will calculate the average of the signal level measurements in dB. To set the zero reference level for the SNR measurement, enter the averaged value displayed in the Data Editor panel, into the dBrA box which is in the Reference section of the Analog Analyzer panel. 3. Cue and play the Silence track. When making SNR measurements with an interferer present, simultaneously cue and play the appropriate processed pink noise track on CD player #2. After 5 seconds, click on the Go button in the Sweep panel to start taking SNR

measurement data. The Data Editor panel will display the recorded SNR measurements, and when the sweep is done it will calculate the average SNR in dB. 4. Save the raw and averaged SNR measurements by selecting File Export ASCII Data. The data will be saved as.adx files that can be opened in Excel. Measurement of Audio SNR Using the HP Audio Analyzer: 1. Select the CCIR weighting filter. 2. Place the instrument in Quasi-peak detector mode by entering 5.7 SPCL, followed by the AC LEVEL button. 3. Cue and play the Full Scale 1kHz Tone track on the appropriate CD player. 4. While the tone is playing, press the Ratio button twice to zero the measurement. It may be necessary to press the LOG/LIN button to change the readout to dB. 5. Cue and play the Silence track. 6. Visually average the SNR, if necessary, to the nearest tenth of a dB.
3.1.3 IBOC Exciter Shutdown
1. 2. 3. 4. 5. Enter the exciters diagnostic menu. Change the Boot Mode setting to Network, if necessary. Select System Shutdown. If the exciter was shut down in network mode, connect its monitor and keyboard. Reset the exciter by powering it off briefly, and then back on. If the exciter is being started in network mode, it will be necessary to manually load the DSPs from the DOS interface.

3.1.4 IBOC Exciter Reset

Upon restart of the exciter, which is necessary following a change of frequency, it is necessary to verify several menu settings before continuing with tests. 1. 2. 3. 4. After the exciter has finished loading its DSPs, enter its diagnostic menu. Verify that the BMUC Delay is set for 1024 samples. Verify that the Zero Analog Delay option is set to ON. Verify that the analog audio gain is set correctly; if it is not, enter the correct gain. The appropriate gain depends on the test being performed. 5. Set the 5 kHz LPF to the desired state; again, the appropriate setting depends on the test being performed. 6. Exit the diagnostic menu.
3.1.5 Modulation Monitor Configuration/Calibration
1. Under the UNIT SETTINGS menu, disable the INFINITE setting. Go to CALIBRATOR-OFF and set it to ON. The NEG MODULATION display should read 100 and the NEG PEAK, NEG PPM, and NORMAL LEDs should light up. 2. Exit this menu, and go to the POS MOD menu display; it should read 100%. Change to the CAR LEVEL menu display, it should read 100%. This indicates the positive modulation and the carrier level functions are correctly calibrated. 3. Go back to the UNIT SETTINGS menu and turn the calibrator off. 22

3.1.6 Audio Recording

1. In Cool Edit Pro, open a new mono file with 44.1 kHz sampling rate. 2. Click or select record to begin recording audio. 3. When making recordings with an interferer present, cue and play the appropriate undesired cut on CD player #2. The interferer may be started anywhere within its 10 minute length, provided the track does not end during the recording. 4. Cue and play the appropriate desired cut on CD player #1. 5. After the cuts have finished playing, stop the recording. 6. Save the recording using the following nomenclature: rx_RFM_DABstate_int_du.wav, where: rx is one of Delphi, Technics, Pioneer, or Sony, RFM indicates that the recording was made at the moderate RF level, DABstate is one of DABOn or DABOff, int is one of L1, L2, U1, U2, or Host, and du is one of NA, 0DU, 7.5DU, 15DU, 22.5DU, or 30 DU.

Exit the menu and scroll to the POS MOD measurement display. 7. Play the appropriate audio cut, as shown in the table above. When the cut is complete, record the measured positive and negative modulation levels from the front panel of the AM Wizard. The levels should be near +125% and -99%, respectively. 8. Reset the infinite hold measurement by setting INFINITE to OFF under the UNIT SETTINGS menu. 9. Turn off the +24 V power supply.
3.3 Receiver Calibration Procedure
The calibration measurements outlined below were performed on each of the four NRSC receivers individually, immediately prior to starting the NRSC AM Compatibility tests on that particular receiver.

3.3.1 Receiver Setup

1. Place the DUT in the screen cage, and apply power. For the automotive units, set the DC power supply voltage for +12.0 V with a calibrated multimeter. For the Sony boombox, insert new batteries in the DUT, and unplug the isolation transformer from its wall outlet. 2. Verify that the settings of the DUT are as specified in Section 2.2.2. Connect the outputs of the DUT as shown in the Testbed Diagram in Section 2.1. 3. Allow the receiver to warm up for a period of one hour prior to continuing the test, unless the receiver has been warmed up (outside the screen cage) beforehand.

3.3.2 IBOC Exciter Setup

1. If necessary, set the transmit frequency of the undesired exciter to 1.00 MHz by depressing the FREQ button for several seconds, and then entering the frequency. 2. If a retune was necessary, perform the IBOC Exciter Shutdown procedure for the undesired exciter, as detailed in Section 3.1.3. The exciter should not be shutdown in Network Boot Mode. 3. Perform the IBOC Exciter Reset procedure (Section 3.1.4) for each exciter, to verify both are configured correctly. The analog gain settings should be 1.00 and the 5 kHz LPFs should be set to OFF.
3.3.3 RF Signal Power Level
1. Reconnect Cable 36-4DS to the appropriate attenuator, if necessary. 2. Remove all attenuation from the undesired exciters RF signal path, except that of the 1/839 attenuator. Set the attenuation of the 1/839 attenuator to that determined in the Daily Calibration Procedure (Section 3.2). 3. Measure the unmodulated RF signal power being output by the undesired exciter according to the RF Power Measurement procedure (Section 3.1.1). If necessary, adjust the attenuation of the appropriate Kay Elemetrics 1/839 attenuator to produce an RF level nearer to 14.00 dBm. 4. If an adjustment is made, record the attenuator switch settings and the resultant RF power level in the Calibration Results template. 5. Reconnect cable 36-1DS to the spectrum analyzer when the measurement is complete.

3.3.4 Audio Output Power Level
1. Re-connect the output of Splitter #2 to the BNC Bulkhead leading to the DUT. 27
2. Add the necessary attenuation in the Final RF Adjust attenuator to achieve a Strong RF level for the DUT (the appropriate levels are listed in Attachment A). 3. Adjust the volume setting of the DUT to achieve output power as close as possible to the levels in Table 4, without exceeding these levels. The procedure for performing the audio power measurement is detailed at the end of this section. 4. Record the measured power level in the Calibration Results template. 5. Add 14 dB of attenuation to the Final RF Adjust attenuator and repeat the measurement at this moderate RF level. For the objective tests, these measurements were performed using the Audio Precision System II Cascade. For the subjective tests, the HP Audio Analyzer was used. Measurement of Audio Power Using the System II Cascade: 1. In APWin, load the test file named AMCompTests-SNR.at2c. 2. Using CD player #2, play the track with an unprocessed full-scale 1 kHz tone. The audio output power level, in Watts, as measured by the Audio Precision System II Cascade, will be displayed in the Level meter in the Analog Analyzer panel. This audio output power level is referenced to the load impedance value given in the Watts window of the Reference section in the Analog Analyzer panel. For the Pioneer, Delphi, and Sony, use a load impedance of 4. For the Technics, use a load impedance of 10k. Measurement of Audio Power Using the HP Audio Analyzer: 1. Enable the audio analyzers 30 kHz LPF by pressing the labeled button on the front panel, if necessary. 2. De-select the CCIR weighting filter, if necessary. 3. Continuously play the 1 kHz tone track on the CD player. 4. Place the instrument into power measurement mode by entering 19.4 SPCL. The readout will display the measured power into a 4 load. For the Technics, this is not the actual output power, but the power can be calculated based on this measurement and knowledge of the impedance used in the testing.
Delphi automotive unit: 1 Watt (2 Vrms) into 4. Pioneer automotive unit: 1 Watt (2 Vrms) into 4. Technics home unit: N/A (Line level outputs used) Sony portable unit: 0.25 Watt (1 Vrms) into 4.

Table 4 - Audio Output Levels
3.3.5 Audio Distortion Level
1. Measure the audio distortion at this RF level. Record the measurement in the calibration results template. The procedure for performing the Audio Distortion Level measurement is included at the end of this section.
2. Change the undesired exciters analog gain to 0.80 and repeat step 1. Set the analog gain back to 1.00 when the measurement is complete. 3. Remove 14 dB of attenuation from the Final RF Adjust attenuator and repeat Steps 1 and 2 at the Strong RF level. For the objective tests, these measurements were performed using the Audio Precision System II Cascade. For the subjective tests, the HP Audio Analyzer was used. Measurement of Audio Distortion Using the System II Cascade: The distortion level, in percent, is displayed in the Function Reading section of the Analog Analyzer panel when the THD+N Ratio selection is made in the drop down menu. Measurement of Audio Distortion Using the HP Audio Analyzer: Continuously play the 1 kHz tone track on the CD player. Select the distortion measurement by pressing the DISTN button. It may be necessary to press the RATIO or LOG/LIN buttons to switch the reading to % distortion. The distortion is displayed in the instrument readout.
3.3.6 Analog SNR Proof of Performance
For the objective tests, these measurements were performed using the Audio Precision System II Cascade. For the subjective tests, the HP Audio Analyzer was used. 1. Add 14 dB of attenuation to the Final RF Adjust attenuator to achieve a Moderate RF level. At this moderate RF level, perform the Audio SNR Measurement according to the procedure in Section 3.1.2. Record the measurement in the Calibration Results template. 2. Objective testing only: Remove 14 dB of attenuation from the Final RF Adjust attenuator and Perform the Audio SNR Measurement procedure detailed in Section 3.1.2. Record the measurement in the Calibration Results template. Add 14 dB of attenuation to return to the moderate RF level. 3. Add 14 dB of attenuation to the Final RF Adjust attenuator to achieve a Weak RF level. 4. Perform the Audio SNR Measurement according to the procedure in Section 3.1.2. Record the measurement in the Calibration Results template.
3.3.7 Recording Proof of Performance
The Recording Proof of Performance is necessary only when performing the Subjective Testing, because no recordings are made during the Objective Tests and the Lynx One card is not used. Subjective testing only: 1. Remove 28 dB of attenuation from the Final RF Adjust attenuator to obtain the appropriate strong RF level for the particular DUT. 2. Configure the Lynx One Audio Card as described in Section 2.2.2. Set the mixers input trim level for 10 dBV. 3. Using the appropriate CD player, cue and play the Full Scale 1 kHz Tone track. 29

4. Using the Cool Edit Pro audio utility software, start a recording by pressing the record button. 5. Zero the HP Audio Analyzer as described in Step 4 of Section 3.1.2. 6. Cue and play the Silence cut. Visually average the SNR reading of the HP Audio Analyzer to the nearest tenth of a dB, and record this measurement in the Calibration Results template. 7. Once a reading has been obtained, stop the recording in Cool Edit Pro. Save the audio file, using a descriptive naming scheme to properly identify the recording at a later time. 8. Connect the Left Analog Outputs of the Lynx One Audio Card to the HP Audio Analyzers input. 9. Play back the recording using the Cool Edit Pro audio utility software. Zero the audio level for the SNR measurement while the tone is playing, as described in Step 4 of Section 3.1.2. While the silence is playing, visually average the SNR reading of the HP Audio Analyzer to the nearest tenth of a dB, and record this measurement in the Calibration Results template. 10. Compare the measurements taken in Steps 7 and 10 to verify the integrity of the recording equipment.

3.3.8 Noise Floor Check

In the subjective testing, the Lucid DA9624 D/A Converter and the Sennheiser HD600 headphones were used. For the objective testing, the digitalLabs AES converter and KOSS headphone combination was used. 1. Add the necessary attenuation to the Final RF Adjust attenuator to obtain the weak RF level for the particular DUT. 2. Using the CD player, play the silence track continuously. 3. Using the headphones, which are connected to the digital outputs of the LynxONE audio card through the AES/EBU converter box, listen to the noise floor of the test setup including the test receiver for a few minutes. 4. Make a note of any audible abnormalities. For the Sony boombox, connecting the RF Ground Strap shown in the testbed diagram may eliminate any audible 60 Hz hum.
