Left inlet: Number of samples collected for each value in the display buffer. Smaller numbers expand the image but make it scroll by on the screen faster. The minimum value is 2, the maximum is 8092, and the default initial value is 256. In X or Y mode, the most maximum or minimum value seen within this period is used. In X-Y mode, a representative sample from this period is used.

Right inlet: Size of the display buffer. This controls the rate at which scope~ redisplays new information as well as the scaling of that information. If the buffer size is larger, the signal image will stay on the screen longer and be visually compressed. If the buffer size is smaller, the signal image will stay on the screen a shorter time before it is refreshed and will be visually expanded.

It might appear that the samples per display buffer element and the display buffer size controls do the same thing but they have subtly different effects. You may need to experiment with both controls to find the optimum display parameters for your application.

Left inlet: signal to display on the X axis of the oscilloscope
Right inlet: signal to display on the Y axis of the oscilloscope

If signal objects are connected to both the left and right inlets, scope~ operates in X-Y mode, plotting points whose horizontal position corresponds to the value of the signal coming into the left (X) inlet and whose vertical position corresponds to the value of the signal coming into the right (Y) inlet. If the two signals are identical and in phase, a straight line increasing from left to right will be seen. If the two signals are identical and 180 degrees out of phase, a straight line decreasing from left to right will be seen. Other combinations may produce circles, ellipses, and Lissajous figures.
