This figure shows a changing signal level (0.5 μV to 1.9 μV) vs time. If the Aperture is set to 0 ns, the
sample value is 0.5 μV and the sample was captured at the time of the trigger. If the Aperture is set to
200 ns, the sample value is (0.5 μV + 0.9 μV)/2 or 0.7 μV, which is 200/2 or 100 ns after the trigger. If the
Aperture is set to 400 ns, the sample value is (0.5 + 0.9 + 1.3)/3 or 0.9 μV, which is 400/2 or 200 ns after
the trigger. If the Aperture is set to 600 ns, the sample value is (0.5 + 0.9 + 1.3 + 1.7)/4 or 1.1 μV, which
is 600/2 or 300 ns after the trigger.
