is 0 and the range available is always 1 smaller than the bus bits. For
example, when the bus bits is 16, the range available is 0, 1…15.
Next, press CH to specify a channel source for the bit currently selected in
Bit X.

4. Analog Channel Threshold Setting
To judge logic “1” and logic “0” of the buses, you need to set a threshold for
each analog channel (CH1-CH4). When the signal amplitude is greater than the
preset value, it is considered as “1”; otherwise “0”.

Press MATH Decode Options Auto Thre. to turn the auto threshold on
or off.
When the auto threshold is turned on, the instrument will calculate the center
point according to the current waveform trace automatically as the threshold of
each channel before decording.
When the auto threshold is turned off, you can press Thre.Set to turn the auto
setting menu. Press CH1, CH2, CH3, CH4 and use to set the threshold of
each channel. Press 50% to set the current threshold to 50% of the current
waveform trace.
5. Display-related Setting
Press Format to set the display format of the bus to Hex, Decimal, Binary,
ASCII or LINE. Note that LINE format is displayed the acyual value of the
bus in a binary number form, and the order is consistent with the bus
transmission sequence. This format is only valid for the serial bus, because
the serial bus has the difference of bit sequence of LSB and MSB; if bit
sequence of the bus is selected MSB, the LINE format is the same to the
binary format.
