Vertical Scale: The scale of each grid in the vertical direction. For example, when the vertical
scale is 1.00 V/div, the full scale of the oscilloscope is 1.00 V/div*8 div=8 V.
Vertical Offset: The offset of the channel in the vertical direction. When the vertical offset is
0, the channel offset indicator is located in the middle of the vertical axis.
Probe Attenuation Factor: Set the probe attenuation factor to match the actual attenuation of
the probe. The oscilloscope automatically calculates the vertical scale according to the probe
attenuation factor. For example, the vertical scale of the oscilloscope is 100mV/div with 1X
attenuation, and 1V/div if the attenuation factor is changed to 10X. When inserting a
standard 10X passive probe with a probe sense terminal, the oscilloscope will automatically
set the factor to 10X.
：1:1 attenuation, suitable for direct coaxial cable connection or passive probes with 1X
attenuation
：10:1 attenuation, suitable for general passive probes or active probes with 10X
attenuation
：100:1 attenuation, suitable for some high-voltage probes
：Custom attenuation factor
8.5 Timebase and Trigger Descriptor Boxes
Trigger delay: The time offset of the trigger position. When the trigger delay is 0, the trigger
delay indicator is in the center of the horizontal axis of the grid area.
Horizontal scale: Timebase, the time of each grid in the horizontal direction. For example, if
the scale is 500 μs/div, the time of each grid is 500 μs, and the full-screen time range of the
oscilloscope is 500 μs/div*10 div = 5 ms.
# Samples: The number of sample points on the current screen.
Sample Rate: The current sample rate.
