X-Y Display mode on Scopes - additional features with RIGOL DS1000Z-series oscilloscope (DS1074, DS1074Z-S, DS1104Z, DS1104Z-S) Last Updated: 30/05/2014
series offers more in X-Y mode:
In this mode, the Rigol DS1074Z oscilloscope
changes 2 of the 4 channels from voltage-time display mode to voltage-voltage
display mode. The phase deviation between two signals with the same frequency
can be easily measured via Lissajous method. The figure below shows the
measurement schematic diagram of the phase deviation.
To access the Lissajou mode of
your oscilloscope press the horizontal menu button, and then change the time
scale on the screen to X-Y mode. From
here you can choose between CH1-CH2, CH1-CH3, CH1-CH4, CH2-CH3, CH2-CH4 and
CH3-CH4 as your inputs.
NOTE: RIGOL's new DS1000Z-series offers two features in X-Y mode: you can still see a condensed normal signal display (Y-T) at the top margin of the screen and you can also access the Trigger Menu in X-Y mode.
