» Which buildings and structures are located
in the surrounding area?

Radio signals are electromagnetic waves.
When these waves encounter an obstacle,
they will be reflected, attenuated or even
completely absorbed due to their physical
properties.

In general: The lower the frequency, the
better the penetration. The higher the
frequency, the worse the penetration.

» Which negative consequences result from
this?

Especially objects or structures made of
steel or metal can stop radio waves. This
also includes fences made of wire, steel
reinforcement in the masonry or metal
coated window panes.

Leaves from trees or bushes or rain or snow
as well lead to the attenuation or absorption
of the signal.

» Which positive effects does the
surrounding have for the transmission?

Smooth surfaces of buildings made of
masonry or reinforced concrete can be
used as reflection surfaces, in favor of the
transmission quality and range.

» Selection of appropriate antennas

Pay attention to the correct frequency
range! Short antennas are optimal for
mobile applications, but normally are less
sensitive. Long antennas are more sensitive,
but are not appropriate for mobile
applications, as the antenna socket is
exposed to a greater leverage when under
intense pressure and can be damaged as a
result of this.

» Take care that the antennas are (as much
as possible) unobstructed !

Avoid every limitation of the transmission
and reception area by buildings or walls
directly at or in immediate surrounding of
the antenna.

Please make sure that, especially in a
mobile production, the antennas are able to
transmit and receive in all directions freely.

» Pay attention - if possible - to the identical
altitude of transmission and reception
antennas.

2.3. Alignment and positioning of the antennas

Before operation

» Pay attention to the polarization of the
antennas.

Omnidirectional antennas normally are used
in vertical operation. Transmission and
reception antennas always have to be
aligned identically!

Exception:

fast-moving camera work, for example in
operations with steadycam etc.

Possible antenna configuration at the
receiver:

antenna 1 vertical (90°),
antenna 2 horizontal (0°)

or

antenna 1 turned to 45°
antenna 2 turned to 135°

» Installation of antennas
(by grip, universal clamps etc.)

The grip is to be attached exclusively at the
lowest end of the antenna (maximum 4cm
from the lowest end), else the properties of
the antenna will be negatively affected.

2.3. Alignment and positioning of the antennas

» Are the antennas put at a distance from the system via cables ?

Please do pay attention to the length of the antenna cable. Just exclusively use the cable
"AirCell 7" (3m, TNC male / TNC female, Art.No.: 752010006), which is available as an accessory!

Please pay special attention to the quality of the cable and plugs used!

Example: DX-cable Aircell 7

Cable attenuation: . @2,4GHz: 0,36dB per metre

@5,8GHz: 0,65dB per metre

Effect on the range: at 3dB attenuation: range divided by 1,5

at 6dB attenuation: range divided by 2
at 12dB attenuation: range divided by 4

Calculation example: if you remote the antennas at a 5,8GHz-receiver with a 10m long
antenna cable from the system, the attenuation due to the cable will be 6,5dB.
If the range without antenna cable was 2000m, then the range will reduce to 1000m
because of the antenna cable (range 2000m divided by 2).

Via a BNC connector an SDI video signal (HD/SD-SDI) is fed to to the transmitter, which is then
wirelessly transmitted to the appropiate digital video receivers.

Connector: BNC, female, 75 ohms
Standard: ANSI / SMPTE 292M, SMPTE 259M
SDI signal level: 800mV (p-p) nominal ±10%

If the transmitter does not auto-detect a new video format after this has been changed,
please restart the transmitter.

If a video signal contains a lot of noise this produces huge data rates in the encoder. In
cases of extreme noise levels in the original video signal, the resulting data rate can
increase to such an amount that the remaining available data is insufficient to guarantee
a technically proper transmission of the image.

4.1. Starting the transmitter

When the transmitter is switched on it starts with an initialisation which automatically identifies the
video norm of the input signal. The whole process takes no longer than 6 seconds.

As soon as the initialisation is finished the display should look like the above picture.

After the start-up it takes a total of approximately 30 seconds until a solid connection between
transmitter and receiver has been established. During this start-up process, occasional picture
flickering or frame drops are possible.

If the transmitter does not auto-detect a new video format after this has been changed,
please restart the transmitter.

After switching off the transmitter, the last selected program will be saved and is displayed at the
next start.

4.4. Modulation and transmission power

Modulation and transmission power play an important role in the transmission.

Modulation

Choose „HG“ (High Gain) for a robust, almost faultless transmission. It is especially suitable for
mobile applications without line-of-sight-connection between transmitter and receiver. This setting
makes use of the QPSK modulation, thereby considerably reducing transmission interferences
and errors. In return, the image quality is lower than HPQ.

If you select „HPQ“ (High Picture Quality) you operate with better picture quality. This settings
uses the 16QAM modulation, which transfers a higher data rate per second, yet consequently is
more susceptible to transmission interferences and errors.

Please note that setting 16QAM is only available for HPQ models!

Transmission power

This function can switch transmission power to an admitted value. For example a 100mW
transmitter in frequency band 5.8GHz transmission power can be reduced to 25mW (“middle“)
so that the European regulations regarding licence free 5.8GHz-ISM-band are fulfilled.

In case you intend to operate your system according to R&TTE directive and thus without
the need to get an approval of your local/national authorities, please take into account
that, the transmission power (EIRP) may not exceed the maximum threshold value
defined by your local/national authorities!

4.6. Excess temperature

Due to insufficient ventilation or too high ambient temperature the transmitter heats up during
operation. If the maximum temperature exceeds 60°C, a blinking symbol appears instead of the
audio display and shows the current temperature.

If the temperature inside the transmitter exceeds 75°C, the internal electronics switches off and
stops the video transmission. In order to be able to restart the transmitter and thus continue the
transmission, it is inevitable to allow the transmitter a cool down period.

> 60°C » Temperature warning
> 75°C » Switch off

To avoid transmitter switch-off please switch on the internal ventilations. Every passively
cooled transmitter without internal ventilation needs to have sufficient circulation of air.
Never cover the radiator of the transmitter as this suppresses with the heat exchange!

Putting into operation

5. Putting into operation

This checklist is a guideline for the most common problems that occur in practice. It is a
convenient first approach to various issues that will help you save time when working or
troubleshooting.

1. Simple application errors

» The provided voltage is not in the necessary range between 9 and 40 Volts

Voltage below 9 Volt: System does not power up
Voltage higher than 43 Volt: possible damage to the device

» provided Ampage is not in the necessary range from 325mA (at 40 Volt) to 1,444A (at 9 Volt)

» The temperature of the devices is raised by either an application error (e.g. transmitter is

covered with cloth, fabrics, etc.) or infavorable conditions (like permanent exposure to hot
sunlight), thus having a negative impact on the device's performance.

2. Basic check-up of the transmitter/receiver

In order to check the basic functions of the wireless device, please take the following points into
account:

This test should only be made in LOS conditions, the transmitter and receiver must be
placed in visibility range to each other. There must not be any obstacles, barriers, etc. in
between the two devices. Plus, both devices should not be moved during the test.

» Take care that transmitter and receiver are connected correctly.

» Adjust the transmission setting to any "low" profile (HG low or HPQ low)

» Choose an identical channel in both transmitter and receiver.

» The distance between transmitter and receiver should be 5 meter in LOS condition.

There must not be any obstacles between transmitter and receiver !

» The following information should now appear in the display of the receiver for both tuner.

Quality = 100
BER 0.00e-8

» If those values are displayed:

Increase the distance to 30 meters. If the values BER and quality remain constant, both
transmitter and receiver are basically working.

» If the quality level in 5 meter LOS condition is not at 100:

First check the antennas on the transmitter and receiver. If they are connected correctly,
change the channel on the transmitter and the receiver.

3. Channel evaluation

In order to check individual channels regarding interferences by other wieless sources, please do
the following:

» Take care that transmitter and receiver are connected correctly.

» Adjust the transmission setting to any "low" profile (HG low or HPQ low)

» Choose an identical channel in both transmitter and receiver.

» The distance between transmitter and receiver (in LOS condition) should be adjusted until

the receiver displays the following values:

Level (RF): 35-40
Quality (SNR) : 100
BER: 0.00e-8

» If the values for both quality (SNR) and BER remain solid (SNR between 95-100 and BER

between e-8 and e-7) under these conditions, the channel is devoid of interferences.

Troubleshooting

6. Troubleshooting

This checklist is a guideline for the most common problems that occur in practice. It is a
convenient first approach to various issues that will help you save time when working or
troubleshooting.

1. Transmitter / receiver without function (display off)

A. Check power source

--> Power source (battery/camera/mains adapter)

--> Cable (broken?)

--> Contacts (pins, connector)

B. ON/OFF switch (only V-Mount TX, Handheld RX and V-Mount RX)

2. No video signal

A. Check signal feeding at the transmitter

--> Signal source (camera/player)

--> Configuration of video output (no CVBS, SD/HD-SDI only)

--> Cable (according the specifications)

--> Contacts (pins, connector)

B. Check wiring

--> SDI OUT (source) --> SDI IN (transmitter)

--> SDI OUT (receiver) --> SDI IN (monitor)
Connect the SDI Output of the receiver directly to a monitor without further peripheral
equipment in-between, in order to avoid further possible error sources.
(signal converter or distributor)
Ideally you are able to compare both the clean video source with the receiver output signal
in order to come to a conclusion

C. Display of video format at transmitters display

--> Disconnect and re-connect the BNC connector at the transmitter

--> automatic detection of the video format

If the transmitter, despite an error-free check-up of the previous points, does not automatically
show a video format, the fed video signal might not be in accordance with the necessary
SD-SDI/HD-SDI specification (SD-SDI: SMPTE 259M; HD-SDI: SMPTE 292M)

-> if possible cross-check with a standardized signal

D. Check settings and parameters

--> Identical channels at transmitter and receiver

--> in case of multiple pairs of TX/RX: distinct choice of channels

--> Display: Tuner not locked ?

--> transmission system operates in line of sight (5m line-of-sight LOS)?

--> correct antenna (frequency range) in use?

--> Antenna(cable) properly connected?
Should these 3 previous points be correct, please contact the corresponding service
for your area.

A08 - 25.09.2015

27

VTQ WMS HD - V/G-Mount TX

6. Troubleshooting

2. No video signal

--> Explicit peak at receivers OLED display for level & quality
No? --> Check BER: perfect if constant at 0.00 e-8

If BER > 0.00e-8 (z.B. e-7, e-6, etc.):

--> transmission systems works in line of sight (LOS)?

--> correct antenna (frequency range) in use?

--> Antenna(cable) properly connected?

If these 3 points are correct:

--> Change channel (more than one transmitter operates at the frequency?)

Should the problem prevail:

--> Test of identical transmitter with identical parameters

Should the problem prevail:

--> Contact service

3. Transmission range / Stability too low

(Please first exclude all possible error sources mentioned in point 6.1.)

A. Distance between TX and RX too large?

--> TX & RX in proper distance (LOS)?

B. Are the antennas aligned identically?

--> Standard: vertical polarisation

C. Booth receiver tuners displays identical parameters for RF level?

No: --> are 2 identical antennas connected?

--> switch the antennas and connect them to the opposite connector

--> Check and - if necessary - exchange cables
If the error "sticks" to and moves with one antenna or cable, exchange the identified
error source

Yes: --> If quality and bit error rate are bad, then check:

--> Correct antennas (frequency range) in use?

--> Antennas properly connected?

--> Too low distance between transmitter & receiver

--> Minimum 1 meter distance between TX & RX (ideal distance: 10m)

--> Is the frequency occupied by another transmission system?

--> Change channel

Should the problem prevail:

--> Test of identical transmitter with identical parameters

Should the problem prevail:

--> Contact service

Glossary

A1. Glossary

» BAS

(„Bild-Austast-Synchron-Signal“ = Picture blanking synchronous signal)

Common name of the monochrome TV picture signal. It consists of the picture information and the blanking
signal.

» BER

(„Bit Error Rate“)

The bit error rate (BER) is the percentage of bits that have errors relative to the total number of bits received in a
transmission. The BER is an indication of how often a package of data has to be retransmitted because of an
error. Sometimes a slower data rate will improve the transmission quality because the BER might be reduced.

» Booster

In this manual it is the name of an amplifier that increases the transmission power to have a larger range.

» CBR

(„Constant Bit Rate“)

Constant Bit Rate is a kind of compression technology. Using constant bit rate means that the quality is altered
to reduce the information to fit the fixed bit rate. Overflowing the available bit rate can lead to lost bits, whereas
the target of this technology is to stay just under the available bit rate. The degree of success in almost filling
the available space is a measure of the quality and efficiency of the compression system.

» COFDM

(„Coded Orthogonal Frequency Division Multiplexing“)

Coded Orthogonal Frequency Division Multiplexing is a modulation scheme which is used by the DVB digital
television system. It allows the use of multiple carriers. Concatenated error correction is integrated. The guard
interval is selectable. That makes the system resistant against multipath fading and burst failures and therefore
the best choice for mobile receivers.

» DVB-T

(„Digital Video Broadcasting - Terrestrial“)

Digital Video Broadcasting – Terrestrial, a transmission scheme for terrestrial digital television. It uses Coded
Orthogonal Frequency Division Multiplexing (COFDM), which spreads the signals over a large number of
carriers to enable it to operate effectively in very strong multipath environments.

» EIRP

(„Effective Isotropic Radiated Power“)

Effective isotropically radiated power is the amount of power emitted by an isotropic antenna. EIRP takes into
account the losses e.g. of connectors and the gain of the antenna. The EIRP is often stated in terms of dBm,
mW or dBW.

» ETSI

(“European Telecommunications Standards Institute”)

The ETSI is a charitable institute founded to set Europewide standards regarding telecommunication. It was
founded in 1988 on the initiative of the European Committee. It has over 700 members of over 50 countries
inclusive operating companies, service providers, administrations, and producers.

» FBAS

(composite colour picture signal)

The FBAS signal identifys the entire TV signal that is required for the colour – image transmission. It consits of a
colour signal (F), image signal (B), blanking signal (A) and the synchronous signal (S). In English: CVBS
(Colour Video Blanking Signal).

» FEC

(“Forward-Error-Correction”)

This technology is used to reduce the error rate regarding digital data transmission. In the transmitter the
transmission data is coded by the Forward Error Correction so that the receiver is able to recognize and correct
the errors. It is used e.g. on compact discs (CD) or for wireless transmissions.

» Guard Interval (GI)

The guard interval is one of the most important parameters for robustness of the COFDM-signals. It is inserted
between two successive symbols and thereby avoids interference by echoes.

» GoP

(„Group of Picture“)

At this kind of compression pictures for different purposes are compressed at different levels The I-pictures are
compressed regardless of the other pictures. These are the biggest pictures. All other pictures are reduced in
size in regard of other pictures in the video stream. These different kinds of pictures are used in different
frequencies. Typically they appear as so-called GOP (Group of Pictures). One GOP reaches from one I-picture
to the next. Often they have a length of half a second.

» H.264

H.264 (MPEG-4 AVC) is a standard in videocompression. It performs with an approximately 3 times higher
coding efficiency than MPEG2 (h262). This means that with only a third of the data rate compared to MPEG2 a
similar picture quality is achieved. At the same time the computing effort increases by up to the factor 3.

» HF-Performance

(„High Frequency“)

In contrast to EIRP the HF-performance does not measure the radiation power but the pure transmission
performance of a transmitter measured at the antenna output jack.

» ISM

(“Industrial, Scientific, and Medical Band”)

ISM marks frequency bands which can be used for industry, science, and medicine purposes. It is possible to
use them free of licence fees and charges.

» MER

(„Modulation Error Ratio“)

The Modulatio Error Ratio is - according to the DVB standard - a parameter for the assessment of interferences
during the transmission. All perturbations are concentrated in one measured value. The higher the MER value,
the better the signal quality.

» MPEG

(„Moving Pictures Experts Group“)

The MPEG is a experts group which standardizes video compression. MPEG-2 is a MPEG Standard regarding
video and audio data compression. Also this standard is used by DVB-T, the digital television in Germany.

» NTSC

(“National Television Systems Committee”)

NTSC is a system of the analogue colour television in the United States and in parts of Eastern Asia. It is the
pedant to the European PAL Standard.

» OFDM

(“Orthogonal Frequency Division Multiplexing”)

Instead of modulating only a single carrier several thousand carriers are modulated at the same time. Every
single carrier is phase and amplitude modulated and therefore carries the information of several bits per symbol
(typically 2 or 6 bit).

» OSD

(“On Screen Display”)

On the screen a menu of the current picture is displayed. These menus serve for operation and set up of the
devise.

» PAL

(“Phase Alternating Line”)

PAL marks an analogue colour television norm. PAL was developed by Walter Bruch in Germany who applied
for patent in 1963. Main objective of this norm was to reduce the colour line error. The principal concepts of
signal transmission were taken from the NTSC-system.

» QAM

(“Quadrature Amplitude Modulation”)

QAM is a coding method which combines the digital amplitude modulation and the digital phase modulation.
The objective is a constellation of signal points which represent a definite combination of bits.

» QPSK

(“Quadrature Phase Shift Keying”)

QPSK is a digital modulation method. With this method it is possible to transmit 2 bits per symbol. Thus the
exploitation of the available band width can be doubled.

» SDI

(“Serial Digital Interface”)

The SDI Standard describes the transmission of a digital serial video stream. The video data is transmitted
uncompressed with bit rates from 143 Mbit/s (NTSC composite) to 360 Mbit/s (16x9 4:2:2 component). The
digitalized audio data can be transmitted in the horizontal blanking interval. Also the HDTV transmission can be
standardized by SDI which is called HD-SDI. Here the data rate is 1,485 Gbit/s.

» SMA

Sub-Miniature Version A”)

SMA marks a high frequency plug connector for antennas. Appropriate antennas with this connection can be
connected to the system.

» VBR

(“Variable Bit Rate”)

With this compression method video and audio data are transmitted by a variable bit rate. The memory volume
of the therefore used material is compressed in regard of the signal complexity. Per time unit an appropriate
data amount is produced depending of the signal complexity. The opposite of this method is the constant bit
rate (CBR).
