description
Carrier based events
Digilyzer is not able to lock to the
input.
Sample frequency in 1C2f mode is
to high.
The received data eye pattern
opening is less than half of a bit period
(problems on the transmission line).
Violation of the biphase-mark format
of the carrier signal.
A change of the carrier level greater
than 100mV generates this event.
Details about the carrier level (average,
min. and max. carrier level) are
also acquired.
A change of the carrier frequency
greater than 1 Hz generates this
event. Details about the carrier frequency
(min. and max. carrier frequency)
are also acquired.
Frame based events
Validity bit set. This happens e.g.
at a CD player with active error
correction.
