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.
⚫
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-CH4) 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-CH4). 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.
