If the demodulator is locked, this screen shows the following: 
 

This shows the value of Eb/No calculated by the demodulator. The value 
referred to here is the energy per information bit (Ebi), divided by the noise 
spectral density (No). 
 

∆F 

The frequency offset of the received carrier, in kHz, with a displayed resolution 
of 100 Hz. 
 

This is an estimate of the corrected BER. 
 

(Buffer fill state) This shows the fill state (in percent), of the receive Buffer. After 
a reset, it will read 50. A value <50 indicates that the buffer is emptying, and 
>50 indicates that it is filling. 
 

A dBm reading indicating the signal level of the desired receive carrier. 

 

 
 

 
 
The top line displays the value of Remote Eb/No of the demodulator at the distant end of 
the satellite link. The Remote Eb/No will display UNLOCK if the remote DEMOD is 
unlocked. The bottom line shows how much the AUPC system has increased the output 
power. If AUPC is not enabled, the value of TX POWER INCREASE will show as  
0.0 dB. 

 
 

 

 

Select LOAD, STORE or EDIT using the [

←][→] arrow keys, then press ENTER. 

 
The user can store, load up to 10 different modem configurations, or record the date  
and time of stored configurations in the non-volatile memory of the modem. These 
configurations can be viewed using the [

↑] [↓] arrow keys, and their names edited.
