A “Transponder” is the summary of several data
streams on one frequency band (a frequency with a
bandwidth = channel). The wording “Channel” usually
means a broadcasting station.
2 Product Description
The smartmeter T20 is a compact digital meter used to check signals and
locate errors on aerial systems to easily and quickly align outdoor DVB-T
aerials and to identify the optimum location for DVB-T room aerials.
The smartmeter T20 gives several measured values for the selected station, e.g. signal strength and signal quality as numerical values (in %) and
as bar graphs, signal-to-noise ratio (SNR), Modulation Error Ratio (MER)
and bit error rate (pre BER, post BER). Additionally, the user can check the
TV picture quality on the 8.9 cm-wide high-resolution LCD display.

3 General Safety Notes
3.1 Intended Use
The meter is intended for measuring signals on digital aerials and aerial
systems. It is intended for this purpose only and must not be used for other purposes. Please use the accessories only for the purposes described
in this user manual.
General Safety Notes
12 smartmeter T20
Any use other than the intended use is improper and can result in material
damage or even bodily injury.
We assume no liability for any damages or injuries resulting from improper
use of the device.
3.2 Hazards from Improper Use
CAUTION!
Make sure the meter and especially the power plug are
always kept dry.
Do not expose the meter to temperatures below 0 °C.
Connect the power plug only to 100-240 V AC,
50/60 Hz.
Charge the meter only with the supplied power plug.
During electrical storms, disconnect the meter from the
aerial and from the power supply.
Do not put heavy objects onto the meter.
Avoid mechanical influences that can damage e.g. the
LCD display or the housing of the meter.
Do not bend or crimp the cables.
Do not start to use the meter if you can see signs of
damage or if you can hear loose parts inside the device.
WARNING!
Danger of electrical shock from high voltage
Damages on the housing of the power plug or an improperly repaired power plug can expose the user to
mains voltage.
Do not open the supplied power plug.
Have the power plug repaired by qualified personnel
only.
Taking the device from cold into warm temperatures
can lead to condensation forming inside the device.
Do not connect
the device instantly. Leave it switched
off for a few hours.
General Safety Notes
smartmeter T20 13
3.3 Safety of People
When you install and align the aerial, make sure that people cannot be
injured by falling objects, e.g. tools or parts of the aerial.
When working on pitched roofs or close to roof edges, use a safety rope
and secure yourself according to professional practice.
3.4 Lithium-Ion Polymer Battery
The smartmeter T20 is provided with a lithium ion polymer battery. Please
observe the following safety notes for the battery:
WARNING!
WARNING!
Fire and explosion hazard
Any kind of heat (from inside or outside) can trigger uncontrollable chain reactions inside the battery.
Do not store or use the battery in temperatures above
40 °C.
Never connect the two poles (+ and -).
Never expose the battery to high temperatures, e.g.
close to stoves or cookers or other hot objects.
Never store the meter in a car during sunshine. De-
pending on the storage location you can get temperatures of more than 50°C!
Charge the battery only with the supplied power plug.
CAUTION!
Risk of injury
Damages on and improper use of the battery can lead
to fumes leaking from the battery. When inhaled, these
fumes can irritate the respiratory tracts.
Avoid any damaging of the battery.
If fumes leak from the battery, open the window and
seek medical advice if you experience health problems
that may result from inhaling battery fumes.
Initial Start-Up
14 smartmeter T20
CAUTION!
Damages to other objects
Defective batteries can leak and spill battery liquid onto
close-by objects.
Check the objects affected.
Clean or, if necessary, replace the objects affected.
4 Initial Start-Up
4.1 Charging the Battery
Charge the battery completely before you use the meter
for the first time.
The battery can be charged regardless of
• whether the meter is switched on or off or
• whether the battery-switch on the underside of the
meter is set to On or
Off
.
Charge the battery as follows:
1. Plug the power plug into a 230-V socket.
2. Connect the low-voltage plug of the power plug to the low-voltage
socket on the bottom of the meter.
The battery starts charging as soon as you connect the smartmeter T20 to
the power plug.
When the meter is switched off, charging is indicated by a yellow Power
LED. When the meter is switched on, charging is indicated by a continuously moving battery symbol in the display:
Completed charging is indicated by a steady battery symbol filled with
four bars:
An integrated automatic charging system ensures optimum charging of
the battery. Please keep the meter switched off during charging.
Initial Start-Up
smartmeter T20 15
When you charge the battery for the first time, charge it
for at least 5 hours.
• The maximum charging time is 12 hours.
After charging is completed, disconnect the meter from the power plug.
Store the battery at temperatures between 0 °C and
40 °C.
When you store the battery for longer periods, make
sure to charge it every two weeks. This will prevent the
battery from over-discharging.
4.2 Connecting the Meter
4.2.1 Connecting a DVB-T Aerial
Connect the aerial or the aerial system you want to check to the aerial
port on the top of the smartmeter T20.
4.2.2 Connecting an External Video Source (optional)
Connect the video device you want to check (e.g. SAT receiver, PC
graphics card with TV output) to the
Video In and Audio In ports on the
top of the smartmeter T20.
4.2.3 Connecting a USB Data Storage Device (optional)
Connect a USB data storage device (USB memory stick, USB hard
drive) to the USB port on the bottom of the smartmeter T20. Using a
USB data storage device is absolutely required for some of the functions of the smartmeter T20. The manual indicates which functions
these are.
4.2.4 Connecting the Power Plug (optional)
Connect the supplied power plug to the low-voltage socket on the bot-
tom of the smartmeter T20 to charge the built-in battery (see instructions for charging of the battery in the section 4.1).
Initial Start-Up
16 smartmeter T20
The aerial port and the
Video In
and
Audio In
ports are
located underneath the black cover on the top of the
smartmeter T20. Remove the cover to access these
ports.

The transmission frequencies used for DVB-T are the same as UHF and VHF channels used
for analogue broadcasting. In Western Europe, DVB-T uses VHF 7 MHz channels and UHF 8
MHz channels. In digital broadcasting, these channels can be used more efficiently than in
analogue broadcasting, because more than one station per channel can be broadcast (multiplexing).

Displayed item
Meaning
Constellation diagram On the left side of the screen you see a so-called con-
stellation diagram.
A constellation diagram is the graphic reprenentation
of a digital modulated signal (e.g. Quadrature Amplitude Modulation QAM or Quadrature Phase Shift Keying QPSK).
Example: 64 QAM
The more point-source the dots are, the less noisy is
the signal.
MER Modulation error ratio: all signal disturbances are
summarized to one measurement value. The higher
the MER value, the better is the signal quality.
The MER can be worsened by these issues:
Noise (C/N)
Low frequency hum (50/100 Hz)
Inter modulation errors (distortioned amplifiers)
I/Q modulation errors (phase/amplitude)
Signal overlap (DECT phone)
Standing waves (maladaptation or unfavorably
mounted cables)

Meaning
SNR Signal to Noise Ratio. The measure compares the
level of a desired signal to the level of background
noise. It is defined as the ratio of signal power to the
noise power. The higher the SNR value, the better is
the signal.
Pre BER Bit error rate before the error correction („pre“ = „be-
fore“). BER = number of falsified bits during a time period / total number of bits in this period.
Post BER Bit error rate after the error correcti
on („post“ = „after“).
