1.1 What are the Axis Series Transmitters?
The new Axis series transmitter comes in three different packages designed to suit the needs of many
different types of applications. These transmitters both offer excellent coverage, low delay performance
and multiple format/frame rate capabilities that enable users to acquire stunning images via a wireless
connection, at extended non line of sight ranges. By using 2
nd
generation MPEG4 H.264 compression
technology, users can now deploy 2 or 3 cameras within the same bandwidth previously required by a
single MPEG2 system. All modes of DVB-T modulation are also supported.
The increased compression and efficiency of the MPEG4 H.264 encoder offers users additional range with
the added benefit of small size, low latency and low power consumption. In particular, high quality HD
transmissions are now possible using 40% lower band width requirements than those of conventional
MPEG2 systems need, allowing for HD transmission in a single 8MHz DVB-T channel and also being able to
use very robust error correction and modulation settings. Built with a solid aluminum housing, the ability
to transmit images in a non-line of sight environment at ranges well over a ½ mile and its low delay
capabilities makes this transmitter a very formidable workhorse to suit almost all your RF needs.
The AXTX1 camera back transmitter is a rugged, digital video transmitter, ideal for Sports, ENG News and
other Broadcast applications and the AXTX1M-Mini and AXTX1MB-Mini B are smaller packaged version
geared towards Digital Cinema and Video Assist applications.
The AXTX1 camera back transmitter can have either Anton Bauer or Sony “V” Mount battery plates
installed to facilitate easy mounting to most camera types. The AXTX1M-Mini has a Sony “mini” battery
mount, as well as a threaded mounting hole on the bottom of the unit to attach to a wide range of camera
brackets for easy mounting of the AXTX1-Mini to many different style cameras. While the Axis series
transmitters can be operated with almost any receiver that supports DVB-T signals, we recommend using it
with the Wave Central AXRX1 receiver. The AXRX1 receiver is available in many different configurations
with options for 2-way, 4-way, 6-way and 8-way diversity.

1.3 Applications
The Broadcast Transmitter has been designed to operate in multiple roles in many environments. Here are
some examples:
1.1 Professional Camera Back Applications – Sports and News
We can supply either Anton Bauer or Sony “V” mounting plates that enable the camera back transmitter to
be directly connected to professional cameras.
The Sony “V” mount, for example enables the transmitter to be mounted directly onto cameras such as the
SONY PDW Series Cameras and Thomson 8000 Series. The transmitter mounts between the camera and
the battery. The camera is powered from the battery, through the AXTX1 transmitter, powering both units.
The AXTX1 is also available with Anton Bauer connectors to directly mount onto Panasonic and Ikegami
ENG type cameras.
1.2 Helicopter Integration for Sports, News and Traffic Coverage
A variety of installation options can be made much simpler and easier to operate, by using either of the
AXTX1 transmitters. By having ASI in/out connectors, the AXTX1 allows for specific “Heli-Tele”
configurations and options.
1. ASI out: Can be used to encode an HDSDI signal from a gimbal mounted camera to ASI, which is then
fed to an RF amplifier and directly coupled to an antenna. (Minimal RF loss)
2. ASI in: Can be used in an aerial “re-trans” system. Signals sent up to a helicopter from ground vehicles
and then sent to remote receive sites, miles away.
3. The small lightweight AXTX1-Mini is perfectly suited for these types of applications.
1.2.1 System Integration into Vehicles or Aircraft
Users should be aware of the following issues when integrating the equipment into vehicles.
1. For the additional range required in vehicle applications, the use of amplifiers should be considered.
Interconnection between the transmitter and any power amplifier should be kept as short as possible,
but where this is not possible, special attention should be taken to use only low loss cables.
2. Long cable runs from the RF output to the antenna should be avoided, for maximum RF output.
3. The antenna should be mounted vertically ideally, and exposed to free space.
4. The equipment should be supplied with a clean supply in the range 7V to 18V and capable of 1.10A
maximum at 12VDC. Care should be taken to avoid direct supply from the vehicle 12V which can be
very noisy. Power conversion will be required for 24V vehicles.
5. The video input can be connected across long video cable lengths so remotely mounted cameras should
pose no problem.
6. Insure for proper ventilation of equipment, especially RF transmitter and Amplifiers.

These guidelines will help you install and set up your system. As a general rule we connect in order:
Antennas
Signals
Power
6.2
Connecting Antennas
Each AXTX1 unit requires one antenna. The antenna must be fitted before the unit is placed into RF
mode.
6.2.1 Assembling the Antenna System
AXTX1 units normally use simple Omni-antennas and do not require any rigging. Naturally, it is possible to
use a variety of antenna types for specialist applications.
6.2.2 Attaching the Antenna
You’ll need an AXTX1 and one antenna. An ANT2-200250, 2dBI flexi N-Type mount antenna 2.00 to
2.50GHz would be a typical example for an S-Band variant.
1.
Connect the antenna to the N-Type N connector on the top panel of the transmitter unit.
2.
Do not over tighten the antenna – hand tight only!
CAUTION: Antennas should be connected directly to the unit. If you have to use cables between the
antennas and the AXTX1 (in a mobile application for example), keep them short and use very high quality
cable.
Note: There are many types of antenna that can be fitted to the AXTX1 unit. Your antennas may look
different from those in this guide.
6.2.3 Antenna Polarization
COFDM links are very robust and are tolerant to changes in antenna position, however, it is important to
try and keep the antennas in the same plane if possible.
The antennas used with the COFDM links are normally linearly polarized.
6.3

8 . Advanced Operation
8.1
General
These guidelines will help you perform advanced operations on your radio.
8.2
Encryption
Your material is a valuable asset to your organization and naturally you don’t want others intercepting your
radio signal. To do this, all that they need is a radio receiver that operates in the same mode and on the
same frequency you are using to transmit.
8.2.1 Encryption System
If the AES scrambling option has been purchased for the Axis system in use, then it is possible to encrypt
the link. Both Bcrypt128 and BCrypt256 are license-controlled features. You’ll need to encrypt the traffic
leaving the transmitter and set up the receiver for decrypt.
8.2.2 Switching on the Transmitter Encryption
Here’s how you set up Encryption on the device:
1.
Connect your radio to your PC and run the control application (see Ch10, Control System)
2.
In the Scrambling combo box click the drop-down arrow and select an encryption type. (AES128 for
example).
3.
Click the Encryption button (yellow key icon).
4.
The Write encryption key dialog box will open
5.
In the Key type combo box click the drop-down arrow and select the key type you want to write.
(Should match the key type you chose in step 1).
6.
In the AES128 key text box, type the encryption key you want to use.
7.
Click the OK button.
![](/img.php?id=2642091&img=bg23.png)
35
Figure 8-1 Switching on Transmitter Encryption
8.2.3 Number of Encryption Key Characters Required
In our example above we used AES128 encryption. This needed a key of 32 characters. If we had chosen
AES256 it would need a 64 character key which we spread over two fields like this:
Figure 8-2 Write Encryption Key Dialog for AES256 key Type
Key Type
Number of Characters Needed
ABS
8
AES128
32
AES256
64 (32 in each field)
![](/img.php?id=2642091&img=bg24.png)
36
Note: AES128 uses the same key entered as AES256 (lower). Therefore, setting one will overwrite the
other. In the same way, Bcrypt uses the same keys as AES. ABS is entirely separate.
![](/img.php?id=2642091&img=bg25.png)
37
9 . Control System
9.1
General
To get the most from your radio system you must customize the programming for your operations and
area. Use the Transmitter Control Application to navigate to the system setting you want to customize.
CAUTION: Before you start programming your radio make sure the batteries are fresh and fully charged.
If the radio loses power while you program it, its memory might be corrupted which will require you to
reset defaults. All information programmed in the radio might be lost. It is recommended the use an AC
adapter to power your radio.
The control system provides equipment that controls the communication system, to keep it functioning in
proper and stable order. It enables you to change many of the settings of the radio like frequency or
bandwidth.
The control system may be in the form of a Control Application that runs on your PC connected to the
device using Serial communications. The AXTX1 uses this system.
Alternatively, it may be in the form of Control Pages that are viewed on your PC browser when connected
to the device using IP communications.
9.2
Connecting your PC to your Radio
The AXTX1 has a Control Application which enables you to perform many configuration tasks quickly
and easily. This section tells you how to connect your PC to the transmitter and then configure the unit
using this Control Application.
9.2.1 Installing the Control Application
Install Control Application system onto your Personal Computer (PC). It comes as a simple exe file which
you just place on your desktop or other convenient location on your PC.
It does not need to write anything to your registry.
Remember, the AXTX1 is very simple to operate using its control panel after it has been fully configured
using the Control Application.
9.2.2 Serial Connection between Radio and PC
You’ll need a fully powered AXTX1, USB Cable and a personal computer running the Control
Application.
1.
Connect the USB cable into the USB connector (bottom of AXTX1).
2.
Connect to other end of the USB cable to your PC.
9.2.3 Starting the Control Application
1.
Power up the radio.
2.
Double-click the Solo4 transmitter control icon on the PC
3.
The PC and Transmitter negotiate a serial connection (this may take several seconds)
4.
The AXTX1 Transmitter Control window opens
![](/img.php?id=2642091&img=bg26.png)
38
9.2.4 Logging in to the Control Application
You do not require a login to access the AXTX1 with the Control Application.
9.2.5 A Look at the Main Window
Every Windows based application must have a main window as its entry point function. For the transmitter
Control Application, this is the AXTX1 transmitter control window:

9.3.19 Basic Setup Pane - Quick Setup
There are several basic setup fields that enable you to do a quick setup of the unit without getting into
fine details. (We’ll meet those later).
There are the six basic things to setup:
Basic Setting
What you
can do…
Output frequency (MHz)
Type in the
frequency
that you want this device to
use in megahertz (MHz).
If you type in a frequency which is out of range, the
unit will automatically round to the highest or lowest
frequency which actually is available.
The transmitter frequency can be set in step sizes of
125kHz.
Bandwidth mode
In this combo box the drop
-
down arrow enables you
to choose between DVB-T modes.
Note: To select 6MHz or 7MHz DVB-T modes the user
must first click the Advanced button to enter the
Advanced setting page.
Video Input
You can select the type of camera you want to
connect to the transmitter.
Note: If you select an HD Video Input a second drop-
down box will open to the right where you should
select the resolution and scan frequency.
Audio Encoder 1 and 2
In this combo box the drop
-
down arrow enables you
to select the audio source.
By default, audio encoder 1 is set to Embedded and
audio encoder 2 is Off. You can select:
Off, Embedded or Analogue
The audio settings are optimised based on the bit rate
of the selected transmit mode.
Scrambling
If the encryption option has been purchased it is
possible to encrypt the link.
In this combo box the drop-down arrow enables you
to choose between various encryption modes. (See
Note-(1)).
Note-(1): Some encryption modes are licensed features. If you are not licensed for these modes you’ll
be able to select them from the drop-down list but when you click the Apply button the combo box will
drop back to off automatically.
9.3.20 Understanding Presets
There are sixteen presets available to you. You can set up just one of them if you want but it can be very
useful to have all sixteen populated. Try having different frequencies and range settings available.
![](/img.php?id=2642091&img=bg2e.png)

9.6.3 DVB-T Settings (2)
On the AXTX1 Transmitter Control window in the Bandwidth mode combo box, it is possible to select
DVBT mode. This uses a wider Bandwidth of 6, 7 or 8MHz.
When selected, this next set of DVBT parameters now become important. (They are ignored when we
are working in narrowband or Ultra narrowband).
DVB-T stands for Digital video broadcasting, terrestrial. It’s the same standard that’s used if your
digital TV at home gets its signal from a conventional antenna.
Unit Parameter

Notes
DBVT FEC rate
1/2, 2/3, 3/4, 5/6
and 7/8
Default is 1/2.
The forward error correction (FEC) rate which is
being applied to the DVBT mode in use.
Think ‘data bits/all bits’
1/2 means 1 bit out of 2 bits is data and therefore
1 bit is used for error correction.
Little user data means less picture quality, but
![](/img.php?id=2642091&img=bg33.png)
51
more error correction means a more robust signal
and therefore more range.
7/8 means 7 bits out of 8 bits are data and
therefore 1 bit is used for error correction.
More user data means better picture quality, but
less error correction means less robust signal and
therefore less range.
DVBT guard
interval
1/32, 1/16, 1/8
and 1/4
Default is 1/32.
The guard interval which is being applied to the
DVBT mode in use.
The guard interval is a deliberate extension of the
RF symbol period to give immunity to reflections.
1/32, short extension, deals with fast reflections,
more data, less range.
1/4, long extension, deals with slower reflections,
less data, more range.
DVBT modulation
QPSK, 16QAM
and 64QAM
The COFDM constellation in use.
QPSK-less user data, more robust, more range.
16QAM-more user data, less robust, less range.
(link performance reduced by 5db)
64QAM-max user data, least robust, least range.
DVBT spectrum
inversion
Normal or
Inverted
Default is Normal. You would only use inverted if
you were using a non-compliant down converter
that inverted the COFDM spectrum.
DVBT 4KHz
offset
None, +4KHz or
-
4KHz.
A legacy feature to overcome extremely narrow
band interference. Enables the whole DVBT
frequency to be shifted a very small amount to
counter this problem.
Network Name
Unit1 is the

selected.
Let’s say you chose an HD 1080 format. This
is actually 1920 x 1080 where 1920 is the
horizontal resolution.
If you choose Full then you’ll see all 1920
pixels, if you choose 1/2 you’ll see a down-
sampled picture which requires much less
bit-rate to encoder.

sampled picture which requires much less
bit-rate to encoder.
Note: Using a sub-vertical resolution will
force the Encoding mode to progressive.
GOP Length
Default
Intra only
2 to 64 frames
GOP means Group of Pictures. The default
results in a GOP length equivalent to 1
second. (See Part-B Concept Guide, for an
explanation of GOP structures).
Shorter GOP, less delay, lower quality video,
more error resilience.
Longer GOP, more delay, higher quality
video, less error resilience.
Note: This option only affects Standard
delay Encoding modes.
DTS Delay (ms)

Advanced Encryption Standard
(
AES
)

standard comprises three block ciphers, AES-128, AES-192 and
AES-256, adopted from a larger collection originally published as
Rijndael. Each AES cipher has a 128-bit block size, with key
sizes of 128, 192 and 256 bits, respectively.
Amplification
The process of increasing the
strength (current, voltage or
power) of a signal.
Amplitude
The level of an audio or other signal in voltage or current. The
magnitude of variation in a changing quantity from its zero
value.
Amplitude
Modulation
Modulation in which the amplitude of the
carrier wave is varied
above and below its normal value in accordance with the
intelligence of the signal being transmitted. Also called AM.
Analogue
Analogue transmission
is a transmission method of

a continuous signal which varies in amplitude, phase, or some
other property in proportion to that of a variable.
Antenna

antenna
(or
aerial
) is a transducer designed to radiate or
receiver electromagnetic energy (generally RF).
Antenna Bandw
idth
The frequency range over which a given antenna will accept
signals.
Antenna Gain
The effectiveness of a directional antenna as compared to a
standard non-directional antenna. It is usually expressed as the
ratio in decibels of standard antenna input power to directional
antenna input power that will produce the same field strength in
the desired direction. For a receiving antenna, the ratio of signal
power values produced at the receiver input terminals is used.
The more directional an antenna is the higher is its gain.
Attenuation

63
from a camera to digital data.
F
Means…
FEC
Forward Error
Correction
is a system of error control for data
transmission, whereby the sender adds redundant data to its
messages, also known as an error-correction code. This
allows the receiver to detect and correct errors (within some
bound) without the need to ask the sender for additional data.
The advantage of forward error correction is that a back-
channel is not required, or that retransmission of data can often
be avoided, at the cost of higher bandwidth requirements on
average. FEC is therefore applied in situations where
retransmissions are relatively costly or impossible.

is an electrical engineering
measurement defined as the ratio of a signal power to the noise
power corrupting the signal.
Signal-to-noise ratio compares the level of a desired signal (such
as music) to the level of background noise. The higher the ratio,
the less obtrusive the background noise is.
Signal
In electronics, a signal is an electric current or electromagnetic
field used to convey data from one place to another. The
simplest form of signal is a direct current (DC) that is switched
on and off; this is the principle by which the early telegraph
worked. More complex signals consist of an alternating-current
(AC) or electromagnetic carrier that contains one or more data
streams.
