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.
Set the endian
In
Endian, select "Invert" or "Normal" as the endian of the bus.
Set the polarity
In
Polarity, select "Positive" or "Negative" as the data polarity.
15.1.3 Display-related Settings
In Decode menu, set the following display-related parameters.
Set the Display Format
Click or tap the drop-down button of
Format to select the display format of the bus
data and event table. The available options include "Hex", "Dec", "Bin", and "ASCII".
Set the Label Display
Click or tap the
Label on/off switch to enable or disable the label display of the
decoding bus. When enabled, the bus label will be displayed at the upper-left side of
the bus (when the bus display is enabled). The label shows the current bus type.
15.1.4 Event Table
The event table displays the decoded data and the corresponding decoding
information in time order in the form of a table. It can be used to observe relatively
longer decoded data. The decoding information includes the decoded data, the
corresponding line number, and time information.
