Set the Width
When the "BUS" setting is set to "User", you can set the bus width. Click or tap the
input field of
Width, and then use the pop-up numeric keypad to set the width. You
can also use the corresponding multipurpose knob to set the value.
Specify data channel for each bit
When the "BUS" setting is set to "User", you can specify the data channel for each bit.
Click or tap
Bit X set the bit of the channel. By default, 0 is selected. Its available
range is from 0 to (width - 1).
Click or tap the drop-down button of
CH to select the data channels for a bit.
Available sources include analog channels CH1-CH4 or digital channels D0-D15. Only
when the digital channel probe is connected, can you select the digital channel (D0-
D15) as the data channel for the specified bit.
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 corresponding multipurpose knob to set the
value. The range of the threshold is related to the current vertical scale and offset.
