In this case, bits b5 and b2 have been asserted, indicating that there are two types
of errors:
b5
b2
YY: This complementary information is also expressed in hexadecimal. The value
of each bit indicates a possible anomaly in the operation of the circuit. In all cases, a
deviation with respect to the value of reference indicates a failure in some of the circuits
that compose the modulator. Contact technical assistance (CSC) for repair.
The value of reference (all OK) is 1B, which corresponds to the following value of
each bit:
HEX
Bits b7 and b6 are always "0". Bit b1 is always "1".
A change in bits b5, b4 or b3, indicates failure in the IF generation circuitry (Digital
to Analogue converter).
A change in bits b2 or b0 implies failure in the COFDM DVB-T modulator circuitry.
CCC... C: This parameter is a global error counter. It counts the number of errors
at the moment in which the error message is displayed. Therefore, if an error of any
type occurs continuously, this counter will have a different value whenever we look at
some of the first 16 errors detected by the equipment.
In relation to this value, it must be noted that, in order to detect an error (for
example the loss of synchronization with a TS input), the equipment waits for this
situation to occur for more than 5 seconds. So, it avoids errors in the transitions
between different modulator functions or temporary TS input disconnections to be
counted.
However, the total error counter
regardless of whether or not it lasts more than 5 seconds.
