General information
The MFK 16 DVB-T signal meter meets the highest quality standards based on its
design and highly reliable workmanship. DVB-T signals can easily be measured, as
the spectrum is not relevant and there is no need to see a picture on the screen. Also,
the signal levels of adjacent analogue channels can be represented with the MFK 16.
Additionally, it provides a standard list of all VHF/UHF channels.
This manual tells you how to select the broadcasters covering the individual regions and
all the stations they provide.
The manual features the latest available information. You can find the very latest
information and updates on the Internet at
“www.kathrein.de”.
We will in future be making additional region lists available by way of software
updates.

Charging the battery
When shipped, the battery is not charged. We recommend you leave the battery on
charge for 24 hours before using it for the first time, so that it is fully charged and the
state of charge of the cells is equalised. This recommendation also applies if the unit has
not been used for a lengthy period of time.
The battery must occasionally be recharged, even if the meter has not been in use. After
the battery has been disconnected from the mains power and then reconnected, the
battery charge indicator shows 0 %. The correct state of charge is only indicated once
it has been charged again.
It makes no difference whether you charge the unit from the mains or in a vehicle.
PLEASE NOTE that it is not possible to use the MFK 16 while it is charging.
Charging from the built-in power supply unit
Open the flap on the rear of the MFK 16 to expose the mains power socket. Insert the
mains power cable into the socket and plug the other end into a wall socket. The battery
is fully charged when the display of the MFK 16 shows “Trickle Charge”.
Charging in a vehicle (DC vehicle battery charger leads)
The 12 Volt power socket (12 V DC) is on the right-hand side of the unit. Insert the DC
vehicle battery charger lead into the socket and plug the other end into the vehicle‘s
cigarette lighter. Note that in some vehicles the cigarette lighter only carries power when
the ignition is switched on.
Only the supplied vehicle battery charger lead may be used to charge the unit in the
vehicle. Using any other cable may damage the meter and void any warranty claim.
The MFK 16 can be left connected to any of the charging sources mentioned for a lengthy
period of time in “Trickle Charge” mode without damaging the internal components or
the battery.

indicator.
The second display readout indicates:
- the last region selected,
- the channel number,
- the received HF level in dBμV as a bar indicator,
- the battery state of charge.
Selecting a region
The factory pre-programmed regions enable users to scroll through the channels
in their respective region. This means both analogue (in RF level mode) and digital
transmissions (in BER mode) can be detected. Each region has more than one
transmission channel. Each channel is designated as a MUX (multiplexer). Each MUX
transmits multiple stations.

Getting started
Aligning an antenna / BER mode
Note:
If neither a bar nor DVB-T appears on the display, the signal is too low or the transmission
is analogue.
Real-time Pre BER bar

Carrier-to-noise
(C/N) ratio in dB
Select a channel and BER mode. For the best result, check each channel in the selected
region and set it to the best reception quality, e.g. a peak value on the bar indicator
(PRE BER).

Active 5V antenna switched on
After about 10 seconds the display shows the “Post VITERBI BER” as a numeric value
and the quality stars depending on the reception quality.
A BER of 2E-6 or less together with 3 stars (***) is required for satisfactory
reception.
Check ALL channels for optimum reception quality, e.g. signal peaks for the weakest
channel.
HF level mode
In RF level mode, the meter displays the signal level in dBμV. For levels below 25 dBμV
the under-range icon appears on the display.
If the meter has captured a digital carrier signal, “DVB-T” is displayed. To make this
clear, the acoustic signal changes pitch. If the 75 dBμV level is exceeded, an over-range
icon is displayed. In this case the supplied attenuator must be inserted into the antenna
lead (adding the 10 dB to the level then measured).
