DMM(1)
DMM(2)
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 5A 10 A 13 F RF SG 174.928 MHz 209.936 MHz 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 L1 L12 L23 RF SG 1452.960 MHz 1471.792 MHz 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. DAB receiver
L-band 1452-1492MHz
VHF 174-240MHz

Musicam
COFDM decoder 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). When DAB signal is allocated to TV 12 (approx. 7 MHz)

- 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 Received signal (1.54 MHz) Reallocation of frequency after FFT
Distorted portion by multipath, etc. 2) Time interleave
Disperses distorted carriers by frequency interleave to change them as random error.
Portion containing error caused by multipath, etc. (digital data)
Changes burst error to random error by the time axis. 384ms
Corrects error by Viterbi decoding.

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
Delayed multipath wave S1 S2 Actual DAB signal S1 S2 Direct wave (OFDM wave)
Interference between different symbols (effect of delay) Time required for FFT (1 ms)
Guard interval (250 µs)

S2 Received DAB signal
Time required for FFT for every symbol
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. antenna 1 102.2MHz antenna 2 89.6MHz antenna 3 106.8MHz antenna 1 225MHz antenna 2 225MHz antenna 3 225MHz

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).
