MODEM-Config
Modulation set: qam128_28e6_01 - adjusted modulation (“set mod at xxx”)
Bitrate : 139,61Mbps - bit rate at modem interface
Auto Acquire : on - setting of automatic synchronization
Tx mute : off - setting of output only for supporting frequency
Spectral inv. : auto
Sp inv. status: no inversion
latency mode : standard
Ext. agc mode : auto - setting of attenuation steering on cable
Mse allevel : -29 - value of lower MSE, when it triggers alarm
Ad.mod. config: off
Adaptive mod.0:
Adaptive mod.1: qam32_28e6_01 (-21.5dB,-75dBm) - modulation for worse weather
Adaptive mod.2: qpsk_28e6_02 (-14dB,-81dBm) - modulation for the worse conditions
MODEM-Status
Modem sync (1) : 1 - status of synchronization (1 = OK, 0 = loss, another number = code
of error)
Symbol rate : 24700272Hz - symbol speed (times number of status = “over air” bitrate)
internal AGC gain : -5.2dB - internal forcing of signal from cable (OK = -8 to -1)
external AGC gain : 17.0dB - external forcing of signal from cable (OK = 10 to 25)
carrier offset : -598Hz - offset supporting
MSE : -35.4dB - similar to S/N ration (smaller = better)
possible alarms of modem are:
"Sync byte detector not locked” - sync byte not found
"Equalizer MSI estimator below threshold", - unable to set equalizer
"Symbol timing not locked"
