Section 1
In the loader program you will see a column to select the Channel Bandwidth (BW)
Import and Export buttons are used to move plans , between loader programs easily . Satcatcher will publish small files which can be added to
your loader and users can also send plans to each other. More details of
how to do this are on the CD you received with your meter.
You must add the bandwidth for the frequency you are adding to the plan
you are making. You can select 6 , 7 or 8 MHz for each channel. Check
you local channel bandwidths before you save your plans. Each plan can
have a maximum or 200 channels , which can be a mix of UFH/VHF
analogue or digital, FM and DAB .
Also you will need to know what PAL audio format you use in your country.
This is important when you are configuring your channel plans , as the
Video and Audio frequencies are not the same spacing's , dependent on
which country to are working in.
1. Battery Charging:
Your new meter is supplied uncharged from manufacture and must be
charged using the mains charger for an initial time of 5 hours. This will
optimise the life of the battery for future use. Subsequent charges may be
less. Full charge is shown on the mains charger indicator light on the
mains charger housing. RED light indicates full charge. GREEN indicates
charging in progress. The meter may be used for short periods of time with
the mains charger attached. However we do not recommend prolonged
use. The meter can be left on mains charge and will automatically shut
down when it is fully charged. After the first few initial charges the batteries working time will be optimised. Note: Using powered switches for prolonged periods of time will reduce the battery working time. Note: Only use
genuine Satcatcher accessories supplied with your meter.
2. Vehicle Charging.
You can charge the meter from the vehicle cigarette lighter outlet using
the mains charger and power inverter ( if supplied ). The Vehicle charging
cable can also be used if your meter is supplied with this option.
3. Storage.
Your meter is supplied with a lockable aluminium flight case and foam
protective inserts. We recommend that the meter is stored in this box
when not in use. Keep it stored in a dry area away from sources of water.

Section 2 Item 3
Terminology
For any new user to Terrestrial meter’s this section gives a brief description of some of the words and terms used , It explains the terms in an
easy to understand format and tries not to be so technical. For a more
technical understanding , we advise you to search for the words on the
internet.
CBER — PRE (CHANNEL BIT ERROR RATE) This is the amount of errors in
the bits of information, before any device has corrected these errors. You
will need to have largest Number after the ‘E’ to have the best signal.
VBER — POST (VITERBI ERROR RATE) This is the amount of errors in the
bits of information after the errors have been corrected by the receiving
device. These are corrected by the Meter or the Set top box used. You will
need to have largest Number after the ‘E’ to have the best signal.
LEVEL .This is the actual complete signal that is being received.
COFDM (Coded Orthogonal frequency Division Multiplexing) The modulation scheme used for digital terrestrial signal transmitting. Signals are sent
in various formats as seen below in the QAM explanation.
QAM. (Quadrature amplitude modulation) A way in which some digital
signals are transmitted. 16 QAM and 64 QAM are used for digital TV .You
can interrogate the parts of this signal with the COFDM/QAM test
function. The tighter together the constellation diagrams
(small dots that refresh on the screen) the cleaner the signal. One part or
multiple parts of the quadrant may have errors which you can view.
MER ( modulation error ratio ) This measurement is a calculation of the
amount of errors present in a digital signal. The higher this value , the less
corruption in the signal. Over 25 dB MER is an acceptable level, but must
considered along with good CBER,C/N and VBER readings.
POWER LEVEL .( DIGITAL POWER ) This is the averaged power of the incoming signal. Shown in the search screen as large numbers in the centre
of the screen. The higher the number , the stronger the signal.
C/N (CARRIER TO NOISE RATIO) This represents a calculation of background dirty signal (noise) against the good incoming signals. Aim for the
highest figure of C/N to have the best quality signal.

Editing using personal computer
Your new meter is supplied with a software CD which contains a loader
program which can communicate via a USB connection port on your P.C to
the full USB port on the meter. It is important that you install the program
on your P.C before you connect the meter to your computer. The install will
set up the port as a com port in Device manager on your P.C. You can go
into Device manager and change the port number if you wish. Please refer
to instructions in the readme file on the CD Provided.
Insert the CD into the CD/DVD drive on you P.C and follow this procedure:
On your P.C Click START - MY COMPUTER - Click on the correct drive
for which the CD is loaded. Double Click on the Icon TMAX and you will
see the installation screen appear. Select a location to add the program
and follow the on screen prompts to install the program. After installation
is complete , you will see an Icon appear on your desktop , which you can
use to access the loader program.
The TMAX loader is designed to allow you to edit, add and delete channel
plans for download to your meter. Your meter’s internal memory can store
15 channels plans , with a total number of 500 individual entries.(200
max per plan) This means you can have many channels added in one
plan , or less channels in multiple plans. Each plan can be named as you
wish, with any type of entry being available in each plan. For example :
Plan 1 , you may wish to enter Analogue, FM , DAB and Digital entries of
your local transmitter, with Plan 2 being a plan of the full frequency range
of the channels (21—69 ) with both Analogue and Digital entries present .
You can use the same channel number more than once , as the meter will
prompt you to select which type of you channel you need to test.
There are two screens in the Loader program.
Screen 1 is the configuration screen , which is used to edit current plans ,
delete channels or plans and for adding new channel data to new plans
you wish to add. You can also import and export plans from this screen.
Screen 2 is the Download screen , which is were you select which plans
you want inside the meter before you connect and add them. Pictures of
the two screens can be seen overleaf.
IMPORTANT NOTE : When downloading new plans to your meter, do not
disconnect your Meter or PC until you see the COMPLETE message on both
devices.

MHz (megahertz ) This the unit of measure that this meter is capable of
measuring . The range can be from 46 MHz up to 870 MHz . This range will
cover installations of antenna’s for DAB (Digital Audio Broadcasts ) FM
radio , Analogue TV and DVB-T ( Digital TV ).
BW (Bandwidth ) This the size (width) in MHz of each of the channels on
view. These can vary from country to country. Your meter is capable of
testing 6,7 and 8 MHz bandwidth channels. This is selectable in meter
setup. In the spectrum screen channel BW is automatically found , based
on the frequency selected. EXAMPLE: VHF = 7MHz UHF = 8 MHz.. This
may differ from country to country and will be software configured
before purchase.
When using the spectrum analyzer you can expand these bandwidths to
see a more detailed image of the frequency on test. (Keys 1 to 8 )
PLAN. These are the local settings for blocks of channels that can be
added to the meters memory. The meter can have 15 plans stored inside
with a maximum of 500 individual channels. All of the entries can be edited by hand , or the loader program provided can be used with your PC to
add plans. The data for making these plans can be found on the internet,
from your local antenna supplier, or from your satcatcher dealer. Each
plan can have a maximum of 200 entries.
NOISE. This is signals without meaning, this being found as a by product of
signal transmission or interference. You always find this type of signal with
your antenna, which is also present even in the lower area of good signals.
With high clean signals, noise will not affect your TV pictures or Audio.
Excessive noise will give interference and degrade a good incoming signal.
FREQ (Frequency) This is the scale measured in MHz to define a channel.
Each channel uses a different frequency. FM and DAB radio use a single
frequency for each channel. Analogue TV uses 1 frequency for video and 1
for audio. DVB-T uses a single frequency for audio and video combined.
Different countries , areas , transmitters and sub transmitters can use the
same or different frequencies for channel transmission. You need to check
what your local frequencies are to make a suitable Plan for your meter.
dBuV . The unit of measurement which is the signals Power . Your meter
would normally be set to this unit of measurement.
dBmV The unit of measurement expressed as microvolt's.
dBm
The unit of measurement which is above one milliwatt.

AMPLIFIER (MAST HEAD)
This electronic device is added generally on the mast to which the antenna
is fitted. It adds extra power to the incoming signal, in areas of weak signal
or areas with other signal power problems. This is fitted in line on the coaxial cable from the antenna , normally a maximum of about one meter
from the antenna. These devices require 5 volts or 12 volts or a variable 512 volts to work correctly. Power is provided by the set top box or a separate power supply unit. Your meter can supply 5 Volts or 12 Volts for
testing your installation. In all screens repeatedly pressing the +/- key of
the meter ,adds the voltage required. Powering down the meter , removes
the voltage from the test and needs to be selected again if required ,
when the meter is next powered on.

TV SCREEN.
This screen will allow you to view the TV channels from the selected entry
used for the installation. This is only possible with free to air Digital DVB-T
channels, so please check the frequency used is not encrypted in any way .
When this screen is selected, a notice will appear on screen to inform you
that the meter is searching and downloading the available channels. The
first of the channels will appear on screen, so you can view the picture and
check the picture for its quality and stability. Using the NAVIKEY up/down
buttons , you can move to the next channel if any other channels are
present. The NAVIKEY left /right buttons will control the volume when in
this screen.
To exit this screen press the F4 button from the keypad.
Test Values Explained:
The CBER (Channel Bit Error Rate) gives you an idea of the quality of the
signal. Depending on its value you can tell how good your reception is: CBER <= E-4: this is optimal and you can feel confident with the quality of
the signal. - CBER = E-03: is slightly low and will decrease more when it
starts to rain heavily. Either the antenna type used is wrong, the area is
bad for reception or the antenna is incorrectly positioned - CBER >= E-02:
is too weak to give a clear uninterrupted TV picture.
The VBER (Viterbi Bit Error Rate) which is the error rate after correction.
This with a high CBER result will give a signal reading < E-08 , this is the
highest value.
The LEVEL, is shown as the BAR on the main screen. It is easy to see this
move up and down as you move the antenna. When it is at its highest
point ,then you can check the other results in the search screen.
The C/N is shown in the search screen and is linked to the Pass, Margin
and Fail results. In the top right hand side of the search screen you will see
a P , M or F letter to indicate the status of your test. This is an indicator
only and we recommend you read all the results to determine if the signal
is acceptable. You can set C/N levels in the setup menu to suite yours
requirements.
The V and A (Video and Audio levels for analogue) shows the two levels.
Under this you can see the amount of the difference between Audio and
Video signal. This figure needs to be as low as possible , to avoid high
audio level interference to the Analogue video pictures.
Page 8
ON SCREEN MESSAGES EXPLAINED :
(WARNING! SHORT CHECK 12V. )This message will appear if you have
selected 5v or 12v with the +/- key, without any amplifier present. The meter will automatically shut down to protect itself. Switch the meter back on
and the voltage will be reset to zero voltage automatically.
BATTERY INDICATOR
This can be seen at the top of each screen and shows the status of the
battery power.
SAME CHANNEL NUMBER SELECTION.
The full frequency plan is pre-installed in the meter , with the full frequency
band listed with both Analogue and Digital channel numbers in UFH /VHF.
In the full frequency plan (if installed) , you will see the same channel number may be added for both Analogue and Digital channels. In all the test
screens, when you select a duel entered channel number , you will see a
prompt box appear on the screen , to be able to select either Analogue or
Digital to test. Pressing F1 or F2 will select the correct channel as detailed
in the prompt box. You can only add two channels with the same number
into your plans. If you try to add a third channel with the same number,
you will see an error message on screen.
SHORTCUT KEYS.
The right hand buttons on the keypad can be used to quickly to access any
of the test screens. See page 12 for details.
