SDATA Polarity
Defines the interpretation of high and low signal states.
●
"Active high": HIGH (signal level above the threshold level) = 1 and LOW (signal
level below the threshold level) = 0
●
"Active low": HIGH = 0 and LOW = 1
Remote command:
Threshold setup
Opens a dialog to set the thresholds value for digitization of signals for each line.
If the signal value on the line is higher than the threshold, the signal state is high. Oth-
erwise, the signal state is considered 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 individual values for each line directly in the fields.
"Find thresh-
olds"
Executes the measurement of reference levels and sets the thresh-
olds to the middle reference level of the measured amplitude.
This option is only available for analog sources.
"Couple
thresholds"
Sets all thresholds to the same value. Enter the value in the "Thresh-
old" field.
