The oscilloscope can acquire the waveform according to a normal YT mode at any
sampling rate and can check the corresponding waveform at XY mode.
Control operation is as follows:
The
[Volt/div]
and the vertical
[POSITION]
of channel 1 control the setup of the
horizontal scale and position.
The
[Volt/div]
and the vertical
[POSITION]
of channel 2 control the setup of the
vertical scale and position.
Revolve the
[s/div]
knob to regulate the sampling rate so as to observe the
waveform better.
In XY display format, the following functions are not available:
Waveform arithmetical operation
Cursor
Auto setup (the display format is reset as YT)
Trigger control
Horizontal position knob
Vector display type
Scan type display
At the vector display mode, the oscilloscope connects the sampling points in a digital
interpolation manner, and the interpolation manner includes linear interpolation and sine
interpolation. The sine interpolation manner is suitable for the real-time sampling mode and is
available at a time base of 50ns or faster at the real-time sampling mode.
