Data
Sets the source waveform of the data line. Waveform 1 of channel signals, math wave-
forms, and reference waveforms can be used for decoding. For triggering on a serial bus,
a channel signal is required.
SCPI command:
BUS<m>:LIN:DATA:SOURce on page 701
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. The interpretation of HIGH and LOW
is defined by the Polarity.
There are three ways to set the threshold:
●
"Threshold"
Enter the value directly in the field.
●
"Set to 50%"
Executes the measurement of reference levels and sets the thresholds to the middle
reference level of the measured amplitude.
●
"Preset"
Selects the default threshold voltage for various signal technologies from a list. The
value is set to "Manual" if the threshold was set with "Set to 50%", or was entered
directly.

Bit rate
Sets the number of transmitted bits per second. The maximum bit rate for LIN is 20 kbit/
s.
