Getting started
Aligning an antenna / BER mode
If neither a bar nor DVB-T appears on the display, the signal is too low or the transmission
is analogue.
Note:
Carrier-to-noise
(C/N) ratio in dB
Real-time Pre BER bar
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).
