Measuring timing of video signal
The analyzer provides the ability to analyze signal timing information of an external
HDMI/DVI source device. This feature allows you to test a transmitted HDMI/DVI signal for
anomalies and verify that the proper timing is output by the HDMI/DVI transmitter for a
given signal format.
The procedures below provide instructions for configuring the analyzer through the front
panel. Note that you can also measure timing with the analyzer through the command line.
For procedures using the command line refer to “

The analyzer provides two measurement methods:
•
Basic timing measurement
