HDMI Cable Test Option (780C Only)
- The HDMI/DVI/HDBaseT Cable Test runs a test on all the leads in the HDMI/HDBaseT (CAT) cable and HDMI or HDBaseT networks (when extenders, splitters, switchers and repeaters are used) except the power bus as follows:
- Pixel error test using a pseudo-noise pattern on the TMDS lines using three separate timings:
- 480p60 using 8 bit/component color
- 720p60 using 8 bit/component color
- 1080p60 using 8 bit/component color
- 1080p60 using 12 bit/component (deep color)
- 2160p30 using 8 bit/component color
- Read/write test on the DDC leads and the CEC bus. It reads an EDID at the output from the input.
- Continuity test on the 5V/Hot plug leads.
- Hot plug delay and hot plug pulse width. The hot plug delay is the time that elapses between the falling edge of the hot plug line on the on the sink side of a repeater and the falling edge of the hot plug line on the source side. The hot plug pulse width is the time that the hot plug pulse goes low as detected on the HDMI Tx side.
What you can do:
- Verify HDMI and HDBaseT (Cat5/6) cables. Run tests on HDMI or HDBaseT cables. Test for pixel errors on multiple formats (resolutions) on the TMDS video and check continuity on the 5 volt, hot plug and DDC lines.
- Prequalify HDMI and HDBaseT networks (prior to installation) with Repeater Test. Verify HDMI networks comprised of cables, audio/video processors, extenders, switches, repeaters, etc. prior to installation. Test for pixel errors on multiple formats (resolutions) on the TMDS video and check continuity on the 5 volt, hot plug and DDC lines.
- Test HDMI/HDBaseT networks (once installed) with Frame Compare test. Verify HDMI/HDBaseT networks comprised of cables, audio/video processors, extenders, switches, repeaters, etc. once installed. Test for pixel errors on the TMDS video.
