Bit0 to Bit19 are set to D15 to
CH1 respectively.
 Set the width
When BUS is set to "User", you can set the bus width. Press Width, rotate
the multifunction knob
or use the pop-up numeric keypad to set the
width. The available range is from 1 to 20. By default, it is 16.
 Specify data channel for each bit
When BUS is set to any digital channel, you can specify the data channel for
each bit.
Press Bit X, then rotate the multifunction knob or use the pop-up
numeric keypad to set the bit of the channel.
By default, 0 is selected. Its available range is from 0 to (width - 1).
Press CH, then rotate the multifunction knob to select a channel source.
Press down the knob to select it. You can also press CH continuously or
enable the touch screen to select it. The analog channel (CH1-CH2) and
digital channel (D0-D15) can all be selected as the channel source.
 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-CH2). When the channel signal amplitude is
greater than the preset threshold, it is judged as logic "1"; otherwise logic
"0". Press Threshold, rotate the multifunction knob or use the pop-up
numeric keypad to set the threshold.
 Set the endian
Press Endian continuously to select "Normal" or "Invert" as the endian of
the bus.
 Polarity
Press Polarity continuously to select Positive or Negative as the
