N5998A HDMI Protocol/Audio/Video Analyzer and Generator
Protocol/audio/video analyzer
The N5998A’s protocol/audio/video analyzer supports the HDMI source compliance tests 7-16 through 7-40, with the exception of tests 7-20, 7-21, 7-22 and 7-39. The protocol analyzer captures up to 4 GB of data as shown in Figure 2. The analysis is then conducted in postprocessing.
Prior to the processing, a data file has to be uploaded, and saved on the controller PC. The CTS source audio tests require the minimum sample time of 2 seconds. The minimum file size to meet this requirement for each primary video format is calculated with the formulas below. Note one pixel is 64 bit (8 Byte) in the target file.
The N5998A HDMI software provides the pattern required for the sink tests 8-16, 8-21, 8-23, 8-29, 8-31 and, in conjunction with the Keysight TMDS signal generator E4887A, 8-25.
If you need to generate additional patterns, beyond those defined by the CTS, Keysight in partnership with BitifEye provides a frame generator application. The frame generator (BIT-HDMI-FG-PAG), allows you to define the patterns to generate and automatically sends it out through the N5998A PAG. For more information regarding the frame generator application, please see the related literature section for the datasheet.
required). This enhancement enables the user to export the captured file into a format that can be viewed by the logic analyzer software (no logic analyzer module hardware required). In the logic analyzer software, you will be able to see not only the pixel information, but also see the relationship between the data channels, as well as the control signals, such as V_Sync, H_Sync, video guard band, etc.
The waveform view clearly highlights the relationship between the different signals and allows for easy navigation through markers and zoom-in/zoom-out capabilities. Other tools for the logic analyzer software such as filter and colorization are also available.
