Equipment required:
• Head unit
• SG: Capable of outputting sine waves up to 1.5 GHz (no modulation function is required)
• DMM
• Adjustment stick (with flat tip)
1. VCO ADJUSTMENT
1) Connect the GEX-P900DAB to a DC regulated power supply. Connect the head unit and the GEX-P900DAB with an
IPBUS cable.
2) Set the power to ON, and enter DAB Service mode.
3) Set frequency to 13 F.
4) Check R556 on the side where P1 is located (the side not in contact with D551) with DMM (1) so that VT (tuning
voltage) can be measured. Adjust air-core coil (L553) so that VT is 7.00 V.
5) Set frequency to 5 A, and confirm that VT is within the range from 1.2 to 1.7 V.

2. TRK (Tracking) ADJUSTMENT
1) Connect the GEX-P900DAB to a DC regulated power supply. Connect the head unit and the GEX-P900DAB with an
IPBUS cable.
2) Connect SG to ANT input.
3) Set the power to ON, and enter DAB Service mode.
4) BAND 3 ADJUSTMENT
Set frequency to 10 A. Set SG to 209.936 MHz and 35 dBuV. Then, check SLEVEL terminal (IC 391, Pin 7) with DMM
(2) so that SLEVEL voltage can be measured. Use the adjustment stick to adjust the air-core coil (L473) in front of
FET to maximum SLEVEL voltage. Similarly, adjust the air-core coil (L475) behind FET, as well as the air-core coil
(L477) behind L475. Repeat these adjustment steps several times to set SLEVEL voltage to maximum.
5) L-BAND ADJUSTMENT
Basic adjustment of L-Band is the same as adjustment of BAND 3. Set frequency to L12. Set SG to 1471.792 MHz
and 25 dBuV.
Use the adjustment stick to adjust the air-core coil (L503) in front of FET to maximum SLEVEL voltage. Similarly,
adjust the air-core coil (L505) behind FET, as well as the air-core coil (L507) behind L505. Repeat these adjustment
steps several times to set SLEVEL voltage to maximum.
- Confirmation of Operation
Equipment required:
• Head unit
• RF SG: Capable of outputting DAB signals up to 1.5 GHz (IQ modulation function is required)
• DAB encoder (e.g. KENWOOD DAB-3801)
1. Confirming Operation
1) Confirming BAND 3
Set the encoder to MODE 1.
Set the receiver and RF SG as shown below. Measure the error rate (see Note) to check whether the sensitivity
and maximum input of the specification are satisfied.
Receiver RF SG
5 A 174.928 MHz
10 A 209.936 MHz
13 F 239.200 MHz
2) Confirming L-BAND
Set the encoder to MODE 2.
Set the receiver and RF SG as shown below. Measure the error rate to check whether the sensitivity and maximum input of the specification are satisfied.
Receiver RF SG
L 1 1452.960 MHz
L12 1471.792 MHz
L23 1490.624 MHz
Note:
Error rate is evaluated at 1E-4 if the error rate after correction can be measured. To measure the error rate before correction, evaluation should be made at 5E-2.
The unit operates correctly if the specification is satisfied.

7.3 EXPLANATION
7.3.1 CIRCUIT DESCRIPTION
- What is DAB?
Digital Audio Broadcasting (DAB) is digital broadcasting for mobile communications using the MUSICAM (MPEG
Audio) audio compression system. The system was developed by the EUREKA 147 in Europe. For the digital modulation system, DAB uses Coded Orthogonal Frequency Division Multiplex (COFDM) based on multicarrier.
Internationally, DAB is also called as SYSTEM A in ITU-R.
Digital broadcasting may be called differently in some countries or areas. Even if the system is the same as DAB, it
may be called in different name.
DAR: Digital Audio Radio (IBOC, IBAC or DAB in the United States)
DRB: Digital Radio Broadcasting (DAB in Canada)
DSB: Digital Sound Broadcasting
- What is Coded OFDM?
Although OFDM technology has been known over years, it has recently attracted attention along with development of
FFT technology. In DAB, the system encodes and transmits signal.
1) Encoding is error correction using convolutional code. Compared with codes used in CDs (block code), convolutional code is more effective to handle random errors. Generally, it is called Viterbi decoding.
2) DAB signal requires wide band (1.54 MHz), and is given priority to be allocated to 12 channels of TV in Europe (5-13
channels under the standard). Also used is L-band (1.5 GHz).
Calculating based on band mode 2 will be: 4 KHz × 384 = 1.536 MHz Thus, 1.54 MHz.
Mode 1 1 KHz (1536) Band 3 (VHF) SFN (terrestrial)
Mode 4 2 KHz (768) L-Band (1.5 GHz) SFN (suggested by Canada)
Mode 2 4 KHz (384) L-Band (1.5 GHz) Local (terrestrial and satellite)
Mode 3 8 KHz (192) 3 GHz Cable

- Why DAB is More Effective with Multipath Than FM?
Different from FM, DAB systems are designed under the conditions that multipath exists. DAB disperses the portion
that will be distorted by multipath, and corrects such part with error correction.
1) Frequency interleave
2) Time interleave
Portion containing error caused by multipath, etc. (digital data)
384ms
Changes burst error to random error by the time axis.
Corrects error by Viterbi decoding.
Received signal (1.54 MHz)
Reallocation of frequency after FFT
Distorted portion by multipath, etc.
Disperses distorted carriers by frequency
interleave to change them as random error.

3) Guard interval
The time 25% more than the sampling time required for processing DAB signals by FFT is called "guard interval." For
multipath within the time of guard interval, errors can be corrected in most cases, regardless of the D/U ratio.
Mode 1 2048 points (1 ms): Number of samples required for FFT
512 points (250 µs): Guard interval
The time of guard interval depends on modes. Different time of guide interval is used for transmitting frequency,
receiving speed (vehicle speed), etc.

- What is SFN?
Single Frequency Network (SFN) functions in the same way as with Network Follow (NF) of RDS. The principle of SFN
uses the advantage of DAB that signals can be received for multipath having delay within the time of guide interval.
1) Different from FM, all transmitting antennas use the same frequency in SFN. Thus, completely muteless status can
be achieved in NF.
2) SFN receives frequency from several antennas simultaneously. Thus, network gain may be obtained by several dBs.
Viewing from the receiver, both SFN and mutipath behave in the same manner.

- Broadcasting Content
DAB can be considered as a system that can transmit the conventional seven broadcasting stations using a single
broadcasting wave. New styles of broadcasting can be offered by replacing the content of broadcasting in audio signals with data.
1) Currently, audio quality equivalent to CD for a maximum of seven channels and RDS data of upward compatibility
are transmitted. The capacity of every channel can be quickly changed by technology called "Dynamic
Reconfiguration," thus can increase the number of channels.
2) DAB has transmission capacity of a maximum of 1.7 Mbps (larger than Video CD), thus various types of data can be
transmitted.
3) We are planning to transmit navigation-related data, such as DGPS and TMC, in the future. The DAB signal itself has
a simple system to detect its own position (TII: Transmitter Identification Information), implying a possibility of simplified navigation.
Actual selection of service using a DAB receiver will be as the illustration shown below
(a large display is required).
Currently, use of the DAB standard in future is examined in public organizations in Europe and other areas, including
EUREKA 147, WorldDAB, EACEM, CENELEC, ETSI, and CEPT.
The latest information on DAB can be obtained from home page (http://www.kp.dlr.de/DAB/) via the Internet. The content is shown as a menu that links to detailed information.

Basic Operation
Basic Operation of DAB
1. Select DAB.
When you first switch to DAB, Auto Seek is performed to find the highest
Ensemble frequency. (Auto Seek is also performed in the same way each
time you switch bands.)
Once Ensemble is received, Auto Seek ends.
2. Select a desired Service.
If you cannot find a desired Service, repeat step 2 after switching to
Ensemble in step 3.
3. Tune to a high or low frequency (Ensemble).
4. Turn the source OFF.

Selecting the Ensemble
You can switch to an Ensemble offering a desired Service.
• Tune to a high or low frequency (Ensemble).
By pressing the same button, search stops and the unit switches to standby
for reception of that Ensemble frequency.
Note:
• The initial Language Filter setting is OFF.
Language Filter OFF
Priority is given to the first Service in a received Ensemble. After it is
selected, sound of that Service’s Primary Service Component is output.
Language Filter ON
Search for a Service Component of the set language among the received
Ensemble is performed.
- When a Service Component is found
Sound of that Service Component is output.
- When a Service Component is not found
Priority is given to the first Service. After it is selected, sound of that
Service’s Primary Service Component is output.
