Instructions

Digital Storage Oscilloscope 62
oscilloscope does not display a message to tell you that the mode has been changed
to Normal.
Average: Use this mode to reduce random or uncorrelated noise in the signal to be
displayed. Acquire data in Normal mode and then average a great number of
waveforms. Choose the number of acquisitions (4, 8, 16, 32, 64 or 128) to average for
the waveform.
Stopping the Acquisition: When you are running the acquisition, the waveform
display is live. Stop the acquisition (press the [Run/Stop] button) to freeze the display.
In either mode, the waveform display can be scaled or positioned by vertical and
horizontal controls.
2.10.1 XY Mode
The XY mode is used to analyze phase differences, such as those represented by
Lissajous patterns. The format plots the voltage on CH1 against the voltage on CH2,
where CH1 is the horizontal axis and CH2 is the vertical axis. The oscilloscope uses
the untriggered Normal acquisition mode and displays data as dots.
The oscilloscope can acquire waveforms in YT mode at any sampling rate. You may
view the same waveform in XY mode. To perform this operation, stop the acquisition
and change the display mode to XY.
2.10.2 Roll Mode
In Roll mode, the waveform display rolls from right to left. No trigger or horizontal offset
control of waveforms is available during Roll Mode, and it’s only available when set to
100ms/div or slower.
2.11 Display
The waveform display is affected by settings of the oscilloscope. A waveform can be
measured once it is captured. The different styles to display a waveform on the screen
give significant information about it.
Push the [Display] button and the following menu appears.
