X-Y Mode
Examine the Phase Difference between Signals of two Channels
X-Y mode is a very useful when examining the Phase difference of two signals.
1. Set the +/-/XY control on the front panel to the XY position.
2. Set the switch in the probe to 1X or 10X, depend on your need (see "Set
the Probe Attenuation Coefficient" on P9).
3. Connect the probe of Y Input to the Y-axis signal (vertical axis signal).
Connect the probe of X Input to the X-axis signal (horizontal axis signal).
4. Turn the Volts/DIV knob to set the vertical scale of Y-axis signal. The
vertical scale of X-axis signal is fixed as 0.5V/DIV.
5. The vertical position is adjusted using the
Position knob. The horizontal
position is adjusted using the
◁▷
Position knob.
6. With the elliptical oscillogram method adopted, observe and calculate the
phase difference (see Figure 3- 7).
