130 Chapter 8 Analyzing Digital Sources and Cables
Controlling analyzer using command-line interface
You can operate the Analyzer using the 802 generator’s command line interface. This
section describes Analyzer functions and commands and provides examples of command
sequences you can use to perform Analyzer tasks.
For command descriptions, see Appendix A, “Command Reference.”
Signal timing analysis commands
This section provides command line procedures for viewing signal timing parameters.
Viewing signal timing parameters (on an HDMI/DVI monitor)
This example displays timing and allows you to view real-time, detailed HDMI/DVI signal
timing information from a connected HDMI/DVI transmit device.
To view basic timing information of an external HDMI/DVI source signal:
1. Connect the HDMI/DVI transmit device to the HDMI/DVI Rx connector on the generator.
2. If desired, monitor the video signal received on the HDMI/DVI Rx connector (see page
110).
3. Using a terminal emulator, establish a terminal connection with the generator. Refer to
“Setting up a terminal connection with the generator” on page 14.
4. Enter the following commands to configure the generator to output a digital signal
(HDMI or DVI):
SROP 2 4
This removes analog friendly mode and configures the generator to output either a DVI
or HDMI signal depending on the interface hardware the generator is equipped with
(DVI or HDMI).
5. (optional) Enter the following command to set the status display mode:
SROP 8
6. Enter the following commands to initiate the measurement of timing parameters.
ANIG 1 // enables analyzer images to be displayed
IMGL FormatRx // loads the FormatRX image into the edit buffer
IMGU // applies the FormatRX image to the generator/analyzer
Viewing specific timing parameters
The following is an example of using commands to view the total number of horizontal
pixels and horizontal frequency of the HDMI/DVI signal.
