– Displayed—this trace is on screen when checked, and not visible when not checked.
– Inverted—signal polarity is reversed when checked, normal when not checked.
– Coupling AC—check when sampling an AC signal, do not check for DC signals.
– Peak Detect—use when trying to capture a fast event or signal glitch.
9. The scope samples the signal and internally calculates the best way to display it when Auto
Find is selected. A scale and the vertical position for the zero line of the trace that allows the
whole waveform to fit on the screen is established when Auto Find is selected. If Auto Find is
selected on the trigger channel, it also sets the trigger level halfway between the minimum and
maximum value of the sampled signal to provide a stable waveform.
10. The baseline position is the zero line of the trace, use the slider and arrows to adjust it.
