The sound carrier level is only displayed when key  

[2]

 or 

[3]

 is pressed. 

 

 

NICAM Sound Bit Error Rate Measurement 

 

The bit error rate may be measured for an improved evaluation of the 
Nicam signal sound quality. 

Example

 

 

 

Calling up bit error measurement: 

Press 

[2ndF] [SC] 

Press   

[3]

 

 

 

 

In case there are no bit errors identified due to a strong signal, 

BER=0.000

 is indicated on the display. 

In case there is hardly a signal or no signal at all received, 

OVERFLOW 

is indicated on the display. 

SC: 5.85 MHz
