Also, you may notice that postprocessing the data in the equivalent-time
signal path includes calculating functions, storing data to the waveform
memories, transferring data over the HP-IB bus, or transferring data to and
from the disk.
After the measurements are performed, the data is sent through the display
portion of the oscilloscope. Notice that connected dots is a display feature,
and that it has no influence on the measurement results. The pixel memory
is also part of the video RAM, which is past the point where the
measurements are performed on the data. Therefore, you cannot make
measurements on data in the pixel memory. But, you can make
measurements on data stored to the waveform memories.
