both show ‘0.0'.
Examples:
08.0,13.5,2.5,1.8 means:
Minimum Eb/No observed in the measurement interval = 8.0 dB
Average Eb/No observed in the measurement interval = 13.5 dB
Maximum TPLI observed in the measurement interval = 2.5 dB
Average TPLI observed in the measurement interval = 1.8 dB
LOSS,04.5,0.0,0.0 means:
There was a loss of demod lock during the measurement interval
Average Eb/No observed in the measurement interval = 4.5 dB
Maximum TPLI observed in the measurement interval = 0 dB
Average TPLI observed in the measurement interval = 0 dB
