About This Manual
This manual assumes that you are familiar with using an oscilloscope
−in particular the Teledyne
LeCroy oscilloscope that will be used with QualiPHY
−and that you have purchased the QPHY-
HDMI software option. Some of the images in this manual may show QualiPHY products other
than QPHY-HDMI, or were captured using different model oscilloscopes, as they are meant to
illustrate general concepts only. Rest assured that while the user interface may look different
from yours, the functionality is identical.
