Set the Threshold Level
To judge logic "1" and logic "0" of the buses, you need to set a threshold for each
analog channel (CH1~ CH4). When the channel signal amplitude is greater than the
preset threshold, it is judged as logic "1"; otherwise logic "0".
Click or tap the input field of Threshold, and then use the pop-up numeric keypad to
set the threshold. You can also use the corrsponding multipurpose knob to set the
value. The range of the threshold is related to the current vertical scale and offset.
Endian
In Endian, select "Invert" or "Normal" as the endian of the bus.
Polarity
In Polarity, select "Positive" or "Negative" as the data polarity.
