Data
Sets the source of the selected data line. Usually, the source is one of the analog
channels. Reference and math waveforms are only available if the trigger source is
one of the input channels but not the serial bus.
For triggering on a serial bus, a channel signal is required.
Remote command:
BUS<m>:ARINc:SOURce on page 1711
Polarity
Selects the wire on which the bus signal is measured : "A Leg" or "B Leg". The setting
affects the digitization of the signal.
Remote command:
BUS<m>:ARINc:POLarity on page 1713
Thresholds
Sets the threshold value for digitization of the data signal. If the signal value on the line
is higher than the threshold, the signal state is high (1 or true for the Boolean logic).
Otherwise, the signal state is considered low (0 or false) if the signal value is below the
threshold.
There are several ways to set the thresholds:
●
"Upper threshold" and "Lower threshold"
Upper and lower threshold levels. You can enter the values directly in the fields.
