Kathrein MFK 16 manual Aligning an antenna / BER mode, HF level mode

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.

Carrier-to-noise	Real-time Pre BER bar
(C/N) ratio in dB	indicator

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).

4 Quality stars

*	< 2E-4
**	< 2E-5
***	< 2E-6
****	< 2E-7

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).
