Signal selection
In the table, you select and configure the digital channels that are used in the selected
bus.
"State"
Enables a digital channel, and assigns it to the bus.
"Label"
You can enter a name for each digital channel. The name is displayed
in the diagram.
"Deskew"
Sets an individual delay for each digital channel to time-align it with
other digital channels. The deskew value compensates delays that
are known from the circuit specifics or caused by the different length
of cables. The skew between the probe boxes of the digital channels
and the probe connectors of the analog channels is automatically
aligned by the instrument. You can also set a value that is applied to
all digital channels, see "Deskew offset" on page 903.

D0-D7, D8-D15 ← Signal selection
The buttons select or deselect all digital channels of a pod at once.
Deskew offset ← Signal selection
Sets a general delay for all digital channels. The resulting deskew of a digital channel
is the sum of the general "Deskew offset" and the individual "Deskew".
Remote command:

Threshold setup
Sets the logical threshold. For each sample, the instrument compares the input voltage
with the threshold value. If the input voltage is above the threshold, the signal state "1"
is stored. Otherwise, the signal state "0" is stored if the input voltage is below the
threshold.
To avoid the change of signal states due to noise, a hysteresis is considered.
