Key Points
Persistence. When using persistence, old data retained is displayed in
gray while the new data is black.
With Persistence set to Infinite, record points accumulate until a
control is changed.
XY Format. This format only applies to channels 1 and 2. Choose XY
display format to display channel 1 in the horizontal axis and channel
2 in the vertical axis. The oscilloscope uses the untriggered sample
acquisition mode and data displays as dots. The sampling rate is
1 MS/s and can not be changed.
NOTE . The oscilloscope can capture a waveform in normal YT mode
at any sampling rate. You can view the same waveform in XY mode.
To do so, stop the acquisition and change the display format to XY.
The controls operate as follows:
H
The channel 1 VOLTS/DIV and vertical POSITION controls set
the horizontal scale and position.
H
The channel 2 VOLTS/DIV and vertical POSITION controls
continue to set vertical scale and position.
The following functions do not work in XY display format:
H
Ref or Math waveforms
H
Cursors
H
Autoset (resets display format to YT)
H
Time base controls
H
Trigger controls
