Third oscilloscope screen shot. In this one both traces are active. Because the display on each trace is a colored in figure one trace can cover up another one if it is larger. As it happens trace to is larger in most places but trace 1 shows at a strategic point. Trace one is the from the same source as that shown in the second screen shot. The only difference is that the vertical scale is set to 1 volt per division instead of 700 mV per division. Trace 2 is also set to 1 volt per division. It is in front and when it begins at the left it is about 1 and one half divisions thick, three quarters of a division below zero and three quarters division above zero. It widens out reaching a peak at 1 division to the left of center and 2 and a half divisions above zero. It then droppes off as the trace did in the first screen shot. The floor of the valley is at the center of the screen and almost a whole division below the first peak. It rises to the next peak which is higher than the first being at 3 and one third divisions above zero and one division to the right of center. It then droppes off to end at the right side of the screen and is almost 2 divisions thick. Meanwhile back at the valley trace one is peaking through it because its peak is higher than the valley floor being 2.8 divisions above zero. The two Y cursors have been set to the peak of trace one and the higher peak of trace 2. The difference is shown as 500 mV. From this the insertion loss is calculated in the text.
