Remote command:
BUS:SENT:DATA:SOURce on page 475
Polarity
Sets the idle state: "Idle Low" or "Idle High".
Remote command:
BUS:SENT:POLarity on page 475
Threshold, Technology, Find Level
Sets the threshold value for digitization of signals. If the signal value is higher than the
threshold, the signal state is high. Otherwise, the signal state is considered low.
You can select the threshold voltages for various technologies in the "Technology" list,
or set a user-defined value in "Threshold". You can also let the instrument set the
appropriate threshold using "Find Level".
Changing the thresholds in the bus configuration changes also the thresholds of ana-
log channels in the "Vertical" menu, or the thresholds of logic channels in the "Logic"
menu.

Clock Period
Sets the transmitter-specific nominal clock period (clock tick).
The clock period and signal length determine the speed of transmission.
Remote command:
BUS:SENT:CLKPeriod on page 476
Clock Tolerance
Specifies a tolerated deviation of the clock.
Remote command:
BUS:SENT:CLKTolerance on page 476
Ser. Message Format
Selects the protocol format in the transmitted signal.
"Short"
Short serial messages.
"Enhanced"
Enhanced serial messages.
"None"
No serial messages. Transmission sequences only.
Remote command:
BUS:SENT:SFORmat on page 477
Data Nibbles
Sets the number of data units in a single transmission sequence.
The maximum number of data nibbles is 6.
