●
Vil(max) is being used for the falling edge evaluation. This "l" (low) threshold is the
maximum level for the signal to be identified as "0". If the signal value comes from
a high state (hence, falling edge), the state remains to be considered as high ("1"),
until it has fallen below V
il(max).
There are four ways to set the thresholds for the digitization of the signal lines:
●
"Threshold"
Enter the values directly in the fields.
●
"Preset thresholds"
Allows to select the default threshold settings according to the Ethernet standard:
2.0 V and 0.8 V.
●
"Auto thresholds"
Executes a measurement of reference levels and sets the thresholds to the middle
reference level of the measured amplitude.
●
"Couple thresholds"
Overwrites the data thresholds with the clock thresholds.
