Square: (Multi-period, Single-period, Rising Edge, Falling Edge, Cancel Autoset)
Video signal:
DC level, Unknown signal:
Description for some icons:
Multi-period： To display multiple periods
Single-period： To display single period
FFT： Switch to FFT mode
Rising Edge： Display the rising edge of square waveform
Falling Edge： Display the falling edge of square waveform
Cancel Autoset：Go back to display the upper menu and waveform information
Note: The Autoset function requires that the frequency of signal should be no lower
than 20Hz, and the amplitude should be no less than 5mv. Otherwise, the Autoset
function may be invalid.
Run/Stop: Enable or disable sampling on input signals.
Notice: When there is no sampling at STOP state, the vertical division and
the horizontal time base of the waveform still can be adjusted within a
certain range, in other words, the signal can be expanded in the horizontal or
vertical direction.
When the horizontal time base is ≤50ms, the horizontal time base can be
expanded for 4 divisions downwards.
Single: Push this button you can set the trigger mode as single directly, so when
trigger occurs, acquire one waveform then stop.
Copy: You can save the waveform by just pushing the Copy panel button in any
user interface. The source wave and the storage location are according to
the settings of the Save function menu when the Type is Wave. For more
details, please see "Save Function Menu" on P50.
