Data
Sets the source of the data line.
Usually
, the source is one of the analog channels. Reference and math waveforms are
available as source if the trigger source is one of the analog channels but not the serial
bus.
Remote command:
BUS<m>:
SENT:DATA:SOURce on page 1899
Threshold
Sets the threshold value for digitization of the signal. If the signal value on the line is
higher than the threshold, the signal state is high. Otherwise, the signal state is consid-
ered low if the signal value is below the threshold.
There are several ways to set the threshold:
●
"Threshold"
Enter the value directly in the field.
●
"Autoset"
Starts software algorithms for determining the signal threshold levels and bitrate.
●
"Find thresholds"
Executes the measurement of reference levels and sets the thresholds to the mid-
dle reference level of the measured amplitude.

Clock Period
Sets the transmitter-specific nominal clock period (clock tick).
The clock period and signal length determine the speed of transmission.

BUS<m>:

Clock tolerance
Specifies a tolerated deviation of the clock.

Data Nibbles
Sets the number of data units in a single transmission sequence.
The maximum number of data nibbles is 6.
Remote command:
BUS<m>:
SENT:DNIBbles on page 1901
Serial protocol
Selects the protocol format in the transmitted signal.
"Short"
Short serial messages.
