General Information

DB7000 is a frequency-agile, digitally-tuned FM Re-Broadcast Receiver equipped with a sophisticated and high-selective DSP based FM-tuner. The RF (IF) signal is digitalized as soon as it enters the device and all signal processing is then made through DSP algorithms. The signal being digitalized in this way, at the input, the equipment acquires measurement reproducibility over time. The high-accuracy DSP based IF bandwidth filters help to solve difficult adjacentsignal. The DB7000 measures conveniently all important parameters of FM transmissions. The built-in monitoring system generates automatic warning messages in case of faulty or missing data. The incredible processing power of the device enables all measurements to be refreshed simultaneously and synchronously, thereby allowing for detailed readings of all the Multiplex FM signal components.

The DB7000 has an easy to read, high-resolution OLED graphical display and ultra-bright alarm indicators that allow reading the signal at a glance. An additional feature to the list of

DB7000 characteristics is that the RDS information contained in the processed MPX signal is easily visualized and represented as RDS/RBDS Data and detailed RDS/RBDS Statistics. The

DB7000 is designed to support USB and LAN communication interfaces, allowing flexibility in remote connection and control of the unit. Easy channel status monitoring or audio listening from everywhere is possible through your mobile phone. With the Audio Stream Server you can listen to the audio of the received radio program.

The Band Analyzer function of the DB7000 presents an overview of all FM signals available, plus the RF signal strength of these stations. Scans are possible within any section of the band in the FM band in 3 different modes. The generated spectrum diagram shows the RF Level vs. the

Frequency. Scheduled Band Scans can also be enabled for RF intruder or pirate transmissions detection. In case of a transmission failure, maintenance staff will be immediately alerted via

E-mail, SNMP, or SMS which signals the technicians to restore a normal service as soon as possible.

A high performance level and sustained reliability make the DB7000 to satisfy the requirements of the most demanding broadcasters, as well as the satellite and cable operators. This product has been designed with the latest state-of-the-art audio technology in use, and with very low harmonic distortion!

Our DB7000 meets all necessary requirements of high level FM rebroadcasting.

RF ENVIRONMENT – PRECAUTIONS,

INSTALLATION SPECIFICATIONS AND ANTENNA TYPES

The observation of the RF Environment, in which DB7000 is functioning, is necessary for ensuring normal and reliable function of the device. In order for the device to work properly, the best conditions according the standards listed below should be provided.

The usage of an external antenna is required because DB7000 is used for off air re-broadcasting away from the transmitter site. Proper outdoor FM antenna, antenna location and direction should be selected. The three most popular antenna types are: omni directional, unidirectional dipole and directional multi-element array antenna.

Because of the low antenna gain, the bad signal to noise ratio (compared to any directional antenna) and its high multipath interfaces reception, we do not recommend the usage of omni directional antenna with DB7000.

The other type antennas: unidirectional dipole and directional multi-element array antenna are much proper for your needs. We recommend the usage of factory made antenna or antenna system, manufactured specially for the FM Radio Band 88 – 108 MHz.

The recommended working RF signal strength is in the range of 55-90 dBµV. If the input RF level is above this range, we recommend using external RF attenuators with attenuation value between 20 – 90dB.

After selecting the antenna type that will meet your needs, the next step is its installation. The following important principles should be considered:

- Install the antenna far enough from walls, roofs, buildings or any transmitting equipment;

- The minimum spacing between the antenna and the closest object should be more than 3 meters.

One unit DB7000 re-broadcast receiver is used for re-broadcasting of one transmitter site, transmitting more than one program. In such cases, the best antenna that can be used is a directional antenna directed exactly to this site.

DE-EMPHASIS AND PRE-EMPHASIS SELECTION

As well known, there are three different de-emphasis selections. One of the problems with the high quality VHF FM transmissions is that the increased audio bandwidth means that background noise can often be perceived. It is particularly noticeable towards the treble end of the audio spectrum, where it can be heard as a background hiss. To overcome this, it is possible to increase the level of the treble frequencies at the transmitter. The frequencies are correspondingly attenuated at the receiver in order to restore the balance. This also has the effect of reducing the treble background hiss which is generated in the receiver. The process of increasing the treble signals is called pre-emphasis, and reducing the treble signals in the receiver is called de-emphasis. The rate of pre-emphasis and de-emphasis is expressed as a time constant. It is the time constant of the capacitor-resistor network used to give the required level of change.

In UK, Europe and Australia the time constant is 50μs whereas in North America it is 75μs. The de-emphasis and pre-emphasis should be selected depending on the region you are located or can be disabled.

Operation

RE-BROADCASTING LIMITATIONS

Signal Strength

The signal strength is a major factor when a signal is re-broadcasted, measured and evaluated.

FM compared to AM is less susceptible to the inherent noise of the radio reception.

When speaking about FM broadcasting, it is the monaural reception which can tolerate and profit from a much narrower IF bandwidth. The stereo reception adds all noise present in the 23 –

53 kHz sub-band. The amplitude component (AM) of the sub band is converted down to audible noise and added to the program signal. That is why the noise performance of FM-stereo can be as much as 20 dB worse than that of monaural broadcast.

Better reception and measurement can be obtained by using highly directional outdoors antenna.

This will improve the signal strength and contribute in eliminating the multipath distortion.

Multipath Distortion

In FM reception, regardless of overall signal strength, a very important consideration is that obstacles, which an FM signal may encounter in the line-of-sight path tend to reflect and disperse the signal in many directions. In many locations, especially in urban areas where many tall buildings interfere with the direct transmitted signal or in suburban areas surrounded by hills or mountains, an FM receiver may pick up a station’s primary signal but, also, several secondary reflections coming from various directions. These reflections arrive at the receiver out-of-phase, slightly delayed in time with the primary signal and tend to blur or distort the principal signal. The degree of distortion depends on the number and relative strength of the reflections.

The result, known as multipath distortion in FM reception can range from a low-level fuzziness to a severely distorted sound quality, particularly at the high frequencies or treble. Multipath distortion is especially troublesome in FM stereo reception.

DB7000 has a multipath distortion detector and Front panel multipath LED indicator with adjustable threshold. A bar graph indicator representing the multipath level of the received signal can be reached under LEVELS menu.

Co-channel Interface

In many populated areas, there is not enough space in the radio spectrum and stations might be jam-packed. Poor frequency planning may also result in the mutual interface between the broadcasting stations.

The inherent broad bandwidth of DB7000 re-broadcast receiver is vulnerable from stations working on the nearby frequencies, where signal strength will be the most important factor – the stronger the interfering station, the stronger the interference effect.

We recommend you to observe the independent positive and negative deviation readings in order to identify adjacent channel interference. If the positive deviation is higher than the negative one, interference from a strong station above the monitored frequency would be indicated and vice–versa. For example, the negative deviation can probably be trusted as an indication of total carrier modulation, though this should be confirmed in free of interference RF environment.

Anyhow, the program deviation should be fairly symmetrical about the carrier frequency. Using the built-in Attenuator can be of some help, but the usage of an outdoors directional antenna could improve the situation with unwanted adjacent working stations. Other solutions include a bandpass filter at the primary frequency or a trap at the interfering frequency.

RE-BROADCAST SETTINGS

The Stereo MPX is signal used for FM Stereo broadcasting and represents a complex combination of the following signals:

- Sum of the left and right audio channels occupying the band from 0 to 15kHz;

- Difference signal (Left minus Right) located in the band 23-53kHz;

- Pilot tone at exactly 19 kHz;

- RDS signal, used for transmitting text and other data, may also be added. It occupies a narrow band around 57kHz;

The amount of each signal contained in the final MPX signal is called injection level.

DB7000 has a built-in stereo generator and Radio Data Systems (RDS/RBDS) encoder.

MPX out Configuration

There are three types of MPX signal that you can choose from:

1. RAW MPX - Directly modulated by your station RAW MPX without any further processing;

2. Stereo & RDS Gen - Generated by the internal stereo and RDS generators;

3. Calibration Tone 400Hz – used to adjust the transmitter MPX input.

The MPX signal can be configured through the front panel navigational menu:

Settings> MPX> MPX Source

Stereo Generator

The composite multiplex signal, including the pilot tone, is generated through the build-in

Stereo generator. The Stereo generator can operate in two modes - Stereo and Mono. In order to overcome the noise of the treble frequencies the Emphasis can be set to Flat, 50µs or 70µs.

Injection levels

The MPX signal is a combination of Audio, Pilot and RDS Signal. This option allows you to adjust the amount of each signal included in the MPX. The recommended and default values are:

0dB Audio gain, 7.5kHz Pilot and 5kHz RDS.

MPX limiter

The regulatory authorities, in most countries, require the total deviation not to exceed 75kHz

(100%). Therefore, DB7000 has a built-in MPX limiter that restrains the deviation below the predefined threshold. The preset threshold is 75kHz (100%).

The MPX limiter has 6 levels of processing:

- 0 – Soft processing for better sound quality

- 5 – Hard processing with lover processing delay

NOTE:

All Stereo Generator Settings can be configured through the front panel navigational menu:

Built-in RDS/RBDS Encoder

The use of RDS/RBDS Encoder will allow branding of your station and will enable the transmission of the Program Service name (PS), Program Identification code (PI), Traffic

announcement (TA) and other useful features.

The RDS/RBDS Encoder has four different working modes:

1. Original – Re-broadcast of the original RDS/RBDS data received from the station;

2. Orig/Local fallback – Upon loss of the Original RDS/RBDS the Local data will be used;

3. Replace with local – User-defined combination of the original and local RDS/RBDS data.

One or more values from the following can be modified: Program Identification Code

(PI), Program service (PS), Radio Text (RT), Alternative Frequencies (AFs), Program type

(PTY), Decoder Identification control code (DI), Music – Speech (M/S), Traffic program

code (TP), Traffic Announcement (TA);

4. Local only – User-defined RDS/RBDS data.

NOTE:

All RDS/RBDS Encoder Settings can be configured through the front panel navigational menu:

LEVELS PAGE

Enter the Main Menu page and select the Level icon, press OK button to enter the menu.

Levels page shows bar graph representation of the different signals, measured by DB7000.

The parameters are divided into groups. Each bar graph displays the low, average and high values of the signal. The number in the center below represents the average value. The shaded color number, placed on the left and right bottom edges, denotes the measurement range of the signal.

Measurement units and name of the signal are written above the corresponding bar graph.

Group 1. RF carrier related parameters

The RF level at the selected antenna input is measured in dBμV. The RF attenuation is included in the level calculation.

The Frequency offset of the RF carrier is measured in kHz. This signal measures the misalignment between the modulation and demodulation frequency. As the misalignment is expected to be small, a large offset will indicate disturbance (for example adjacent channel breakthrough).

The Frequency offset is measured with better accuracy if there is no modulation of the carrier.

The usable range depends on the selected IF filter bandwidth. For better results, we recommend the IF filter bandwidth to be manually set to 153 kHz.

The Level of multipath reception is measured in percents. The multipath detector measures the amplitude fluctuations of the signal. The FM signal is broadcast with a fixed level; therefore the level fluctuations will indicate degraded signal quality. At multipath conditions, large level fluctuations can be measured. Install the antenna at the reception point with the lowest multipath

level in order to achieve better re-broadcast.

IF Bandwidth - Shows the currently IF filter bandwidth.

Group 2. Stereo multiplex related parameters

MPX Positive and MPX Negative - These bar graphs represent the positive and negative deviation component of the MPX signal. In wideband FM, used in wireless broadcasting, the instantaneous frequency varies above and below the frequency of the carrier with no modulation.

The carrier frequency shifts in one direction when the instantaneous input wave is with positive polarity аnd vise-verse - when the instantaneous input wave is with negative polarity, the carrier frequency shifts in the opposite direction. At every instant in time, the extent of carrier-frequency shift (the deviation) is directly proportional to the extent to which the signal amplitude is positive or negative.

Mod Input FM Output

Pilot – Represents the deviation caused by Pilot tone injection. Our practice shows that the pilot deviation should be about 10% of the total deviation of the RF carrier.

RDS – Represents the deviation caused by RDS subcarrier. Our practice shows that the RDS

deviation should be about 5% of the total deviation of the RF carrier.

Group 3. Audio related levels

Group 4. Reception quality related levels

Ultrasonic Noise bar graph - Indicates the MPX signal amplitude in the approximate bandwidth of 80 kHz – 150 kHz.

Stereo Blend bar graph - In stereo signals, the difference (L-R) component of the MPX signal is more susceptible to disturbances than the sum (L+R) signal. Therefore, the separation of the left and right audio channels can be decreased in order the audibility of the disturbance to be reduced.

This channel separation reduction is called “stereo blending”. A value of 100% indicates that no reduction is applied. The level of stereo blending depends on the following input signals: RF

Signal Level, Multipath, Ultrasonic Noise and Pilot tone deviation.

High Cut bar graph –Audio disturbance effect is mostly present in the high frequencies.

Therefore, a means of reducing the effect of disturbances is to filter the high frequencies. The audio bandwidth reduction is called “high cut”. A value of 100% indicates that no “high cut” is applied. The applied High Cut level depends on the following input signals: RF Signal Level,

Multipath and Ultrasonic Noise.

Response of the FM High Cut function for several reduction values

Soft Mute bar graph - If a disturbance is present in the received signal, the perceived effect can be reduced by attenuating the audio signal. The reduction of audio volume is called “soft mute”.

A value of 0% indicates that no “soft mute” is applied. Soft Mute depends on the following input signals: RF Signal Level, Multipath and Ultrasonic Noise.

Alarm (ALARM). Alarm is a special parameter type with its own dialog editor. Each alarm parameter is composed of the following sub-parameters:

• Low threshold – the lower alarm limit of the measured signal. If the value stays below this limit for predefined time “low alarm” event will be generated;

• High threshold – the higher alarm limit of the measured signal. If the value stays above this limit for predefined time “high alarm” event will be generated;

• Trigger time – waiting time before a “low alarm” or “high alarm” event is generated;

• Release time – waiting time before an “idle alarm” event is generated;

• Set of notification channels – In case of alarm, maintenance staff will be immediately alerted via E-mail, SNMP, GPO or SMS (the additional GSM modem should be installed), which allows technicians to restore the normal service as soon as possible.

The picture above shows the structure of the alarm editor dialog. The bar graph indicates the signal range of the alarm. The highlighted area represents the permitted signal value range. If current signal value (pos. 4) is in this range, no alarm event will be generated. Basic elements of the alarm editor dialog:

1. Lower limit of the alarm range;

2. Low threshold value;

3. Measurement unit;

4. Current value of the signal;

5. High threshold;

6. Higher limit of the alarm range.

ALARM edit dialog, front panel buttons usage:

Left/Right – Selects previous/next sub-parameter of the alarm.

Up/Down – Change the value of the selected (highlighted) sub-parameter. The value always stays in the permitted parameter range. Low threshold value cannot exceed the high threshold and vice-versa;

OK – Accept the value and exits edit dialog;

SB2 – Toggles ON/OFF the low alarm generation;

SB3 – Toggles ON/OFF the high alarm event generation;

SB4 - Discards all changes and cancels edit mode.

APPENDIX 1: Alarm Triggers

ALARM TRIGGERS

After collecting all the data, the DSP-based core compares the values measured with the predefined by the user threshold levels, for all the alarms monitored. In case that a parameter is beyond limits, the device will initiate the sending of an alarm notification via the selected communication path. All the alarm events are stored in the device’s log. It is essential that, if there is a very short fault of the signal, with duration shorter than the ‘alarm trigger time’, the device would not trigger an alarm.

There are several Alarm Triggers for the following parameters: RF, MPX, MPX Power, Left/

Right Audio, RDS Group loss, Pilot and RDS levels. An option for defining different limits for each of the parameters is present. All these values, the ‘trigger time’ and the ‘release time have to be assigned separately for each of the alarms.

E-mail: [email protected] ,Web: www.devabroadcast.com

When an observation event takes place, the Alarm Trigger’s State will refresh, if necessary.

Should we consider an instance when the Alarm Trigger is in Idle state, having in mind that an alarm is not triggered immediately when a parameter level passes beyond threshold: If the parameter level becomes stable, within Thresholds, and the Alarm Trigger Time is not elapsed, then the

Alarm Trigger remains in Idle state. If the Alarm Trigger Time expires and the parameter level is still beyond limits, the Alarm Trigger would change its state to High/Low. This would result in predefined actions - Alarm Notifications (E-mail, SMS, SNMP trap) and Save a Log Record. The state will not be immediately switched into Idle when the parameter stabilizes, within Threshold levels, not up until the ‘Alarm Release Time’ is elapsed. Meanwhile, if the parameter crosses again any Threshold, the Alarm Trigger will remain in Active state. If the parameter remain within the

Threshold levels and the Alarm Release Time expires, then the Alarm Trigger would switch into

Idle state and again predefined actions would be initiated.

If the RDS Group has not been received within the Alarm Trigger Time, the state would be changed into Active. If the Active state and the Release Time have elapsed and the RDS Group is received, the state is changed to Idle. Should the RDS Group is received before the Release Time is elapsed, the state would remain Active.

APPENDIX A

RDS: EUROPE VS AMERICA

The European Broadcasting Union (EBU) and its member countries originated the concept of

“Radio Data” transmission. The European RDS specification, CENELEC Standard EN50067, was first published in 1984. It was revised in 1986, 1990, 1991 and 1992.

European RDS has grown in use following initial adoption of the Standard. RDS is nearly universal throughout Europe; it is almost impossible to find a European FM broadcasting station that does not carry a radio data subcarrier.

The popularity of RDS in Europe is very much in contrast with initial reluctance on the part of US broadcasters to embrace this technology. This can be ascribed to material differences in broadcasting practices.

Almost without exception, FM broadcasting in the United States is ‘detached’ and independent

- each station originates its own programming. America’s National Public Radio might be considered as an exception, though for most of the broadcast day even NPR stations originate, or at least schedule, their own programs.

Most of European broadcasting is similar to the concept of network radio that was common in the US prior to the 1950s. In Europe, a central program originator may have many transmitting facilities of modest power situated throughout the country, at several different frequencies to blanket a designated service area. The European disposition, toward lower-power transmitters can be found on the “local radio” level, as well.

The European concept of a service area equates to the US broadcaster’s market. The subtle difference between these designations further characterizes broadcasting practices and ethics.

RDS benefits the European broadcaster through almost an altruistic endeavor to be of service to his listeners. The US broadcaster is marketing his programming and is primarily interested in how he can create additional revenue from RDS.

THE RDS SYSTEM

RDS is a digital data channel, transmitted as a low-level subcarrier above the range of the composite stereo program signal in the FM baseband. The data transmission (baud) rate is comparatively low, yet it is quite robust because of data redundancy and effective error correction.

It is not within the scope of this Manual to cover the details of RDS subcarrier coding and modulation. For this, the reader is directed to the Specification appropriate to his location either the

CENELEC EN50067 Specification for Europe or the United States NRSC Specification. Since the

Manual will deal with specific implication of RDS implemented with the DB7000, it is assumed that the user is familiar with the RDS concept.
