Bit Error Ratio Meter; Audio And Video Monitoring; Figure 1.17: Ber Status Meter; Figure 1.18: Audio And Video Monitoring - TANDBERG Alteia Instruction Manual

The LEDs on the front panel indicate the equipment status. The two LED
colours used in this equipment are red and green. Red indicates a fault
condition, e.g. a missing or faulty input signal. All red alarm LEDs should
be off for correct operation, although some may be on during power-up.
NOTE...
The REMOTE LED is the exception to this as it is ON (red) to indicate that the unit is in either
REMOTE or Director OVER-AIR control mode.
Green indicates correct conditions and correct system functioning.

Bit Error Ratio Meter

All Alteia models excluding the M2/PDU/9xx variants are fitted with a Bit
Error Ratio (BER) status meter. This gives an indication of the robustness
of the incoming signal.
The meter shows BER in a range between 10
displayed on the meter indicates that the BER is high and decoding may be
prevented. As the needle moves to the right (further into the green area of
the scale), fewer errors are being received due to fading, interference etc.

Figure 1.17: BER Status Meter

NOTES...
1. Models M2/PTR/9xx (Terrestrial Receivers) dynamically display the current Post-Viterbi BER value
on the front panel BER meter.
2. Models M2/PDU/9xx (Decoders) are not fitted with a BER meter.

Audio and Video Monitoring

Three connectors provide monitoring points for the analogue video and the
two analogue, audio output channels.
