Advanced DVB-S2 Receiver Operational Manual
SR1 Specifications
32
The Status menu includes the following:
Tuner Lock: RF lock of the tuner on digital signal in the configure frequency
Demodulator lock: Lock on DVB-S / DVB-S2 signal
Transport Lock: Transport stream is received with IP packets on it (valid MPE). The Transport
stream will stay unlock until first IP packets will pass through the SR1.
Demodulator Es/No: Provides information about the RF signal quality
Signal Input Level: Provides indication about the RF signal power
Demodulation link margin: Provides information about the margins for a given RF signal and
the MODCOD. Link margin calculation is based on measuring the Es/No and comparing it to
pre-defined thresholds per MODCOD
Demodulation Bad Frame Count: The number of error Base Band frames in the DVB-S2
demodulator.
Demodulation Bad Packet Count: Number of error Transport stream packets in the DVB-S2
demodulator.
FPGA: Loaded indicates FPGA was loaded successfully
The example below shows an example, of the UI when receiver #1 is not locked:
