Logger Event Coding

The following chart lists all details to the Digilyzer Logger event coding.

The remark column states:

• Any format not applicable (n.a.) for the individual events

• Maximum amount of events indicated per second (rec./s) or

“sample“ (= each sample is counted)

Appendix

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 (aver-

age, 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 fre-

quency (min. and max. carrier fre-

quency) are also acquired.

Frame based events

Validity bit set. This happens e.g.

at a CD player with active error

correction.
