XY Mode
In XY mode, voltage levels of two waveforms are compared
point by point. The display is changed from a volts- versus- time
display to a volts- versus- volts display. The time base is turned
off. This mode only applies to channels 1 and 2. Channel 1
amplitude is plotted on the X- axis and channel 2 amplitude is
plotted on the Y- axis. The cursors can be used to make
measurements on XY mode waveforms.
To use the XY horizontal mode
1
Connect a sine wave signal to channel 1, and a sine wave
signal of the same frequency but out of phase to channel 2.
2
Center the signal on the display using the channel 1 and 2
Offset knobs. To expand the signal for convenient viewing,
use the channel 1 and 2 volts/div drop- down list.
N O T E
In XY mode, the time base, delay and triggering functions are disabled. The
Normal trigger mode is enabled.
