adjust the signal rate at a relatively larger step. The adjustable range is
from 10 kb/s to 1 Mb/s.
Note: The larger the rotation amplitude of the outer knob of the navigation
knob is, the faster the variation of the value will be. When you need to
adjust the signal rate within a relatively larger range, this function can help
you quickly finish the setting.
6. Adjust the sample position
The sample point is a point within a bit’s time. The oscilloscope samples the bit
levels at this point. The sample position is represented by the percentage of “the
time from the start of the bit’s time to the sample point time” in the “bit’s time”,
as shown in the figure below.
Press Sample Point and turn the multi-function knob to adjust this
parameter with a step of 1%. The default is 50%. The range is from 5% to 95%.
7. Specify the display format
Press Format and turn the multi-function knob to set the display format of
the bus data to Hex, Decimal, Binary or ASCII. You can also press Format
continuously to switch the current display format.
Note: When the event table is turned on, the decoding data in the event table
will also be displayed in the format selected here.
8. Adjust the vertical offset
Press Offset and turn the multi-function knob to adjust the vertical position
of the bus. Pressing the knob can quickly reset the vertical offset (zero).
