Setting up analyzer to measure timing

114 Chapter 8 Analyzing Digital Sources and Cables
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
page 130.
The analyzer provides two measurement methods:
• Basic timing measurement – Displays limited measurements on LCD.
• Detailed timing measurement – Displays detailed measurements on a display
connected with the generator.
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
page 130.
To operate the analyzer, you must select the desired HDMI/DVI signal source and set
signal format settings and parameters.
To set HDMI/DVI signal source parameters:
1. Start the Analyzer Setup Utility (see page 112).
2. Press and release the Step key.
The Step key illuminates and the Analyzer Images field is highlighted.
3. Using the Format knob, select the Auto Based On field.
