The 980 HDMI Video Generator module supports video and audio functional testing at data rates up to 300MHz for testing 4K Ultra HD TVs at 50/60Hz. The module features two (2) HDMI outputs—both active simultaneously—for testing HDTVs with multiple HDMI inputs. The module also optionally supports analysis functions for testing source devices such as basic video analysis. The module now supports HDMI 2.0 test features for 1) 4K Ultra HD TVs at 50/60Hz using 4:2:0 pixel encoding, 2) 21:9 formats up to 300MHz and reading and 3) displaying EDIDs with HDMI 2.0 capabilities.

The 980 HDMI Video Generator module can be equipped in either of The Teledyne LeCroy quantumdata 980 Advanced Test Platforms:

  • 980B – 3/4-slot, 15″ touch display
  • 980R – 3/4-slot, rack-mountable chassis with a 7″ touch display (Discontinued)

The 980 HDMI Video Generator module is equipped with all the standard video timings and test patterns—including support for 3D—necessary for testing HDTVs including tests for HDMI protocols such as HDCP, EDID and CEC. The module provides compressed and uncompressed HDMI audio formats using a variety of audio test signals.

You can configure the list of format timings and test patterns using the Format List Editor and Image List Editor. These convenient tools facilitate and quick access during testing. The module provides a Format Editor for creating custom format timings or for quickly making modifications to existing timings for testing.

The 980 HDMI Video Generator module offers a variety of features for testing HDMI protocols. The Teledyne LeCroy quantumdata Auxiliary Channel Analyzer (ACA) application enables you to monitor EDID and HDCP transactions between the module and a connected sink device. You can monitor in real time through the 980’s embedded touch display and save files for later viewing or for sharing with colleagues at other locations. You view HDMI data island packets transmitted from the video generator module and a connected display. Test images enable you to view the status and progress of HDCP authentication. The EDID Decode feature enables you to view the contents of the EDID of the connected sink or display in human readable text.

The optional CEC Tester application enables you to send CEC messages and run robustness tests or “irregular” tests on your CEC device using message with bit corruptions, timing variations. You can also simulate irregular non-acknowledgement and arbitration scenarios.

The 980 HDMI Video Generator module can be controlled either through the PC-based 980 GUI Manager or through the embedded 980 GUI Manager running on the 980 itself. The 980/980B built-in color touch screen provides a graphical user interface (GUI) to control the instrument and will enable you to view incoming video and metadata in the Real Time mode when using the module’s optional analyzer feature available in subsequent releases.

The following are a list of features and benefits for the HDMI Video Generator module.

Video Pattern Testing – Test a display’s HDMI inputs with over 600 standard formats to ensure that it can render video test patterns including deep color and HDMI 3D patterns. Over 300 video patterns supported. Create your own custom formats using the user friendly Format Editor. Scroll bitmap patterns to test for motion artifacts. Create custom test pattern lists and custom format lists to facilitate testing.

HDMI Audio Testing – Send audio patterns, tones & noise through HDMI, SPDIF or Optical digital audio outputs. Program audio parameters such as sampling rate, bit depth and channels. Use a variety of audio formats including LPCM and Dolby and DTS compressed formats.

EDID Testing – Identify EDID problems and view the entire contents of the EDID of the sink device in human readable text using simple navigation through blocks and pages.

HDCP Testing – Verify an HDMI HDTV’s response to HDCP authentication. Send HDCP encrypted video content to a downstream repeater (e.g. AVR) and/or sink (e.g. DTV). Check the authentication response from the sink.

CEC Testing – Verify an HDMI HDTVs CEC message response.

Protocol Monitoring – Monitor EDID exchanges, HDCP authentication transactions and CEC messages with an HDMI HDTV or downstream distribution network.

 

The following are a list of options available for the HDMI Video Generator module.

HDMI Network Analyzer

Verify Video Timing and Type – Verify the video timing and video type of an HDMI source. Compare against a known-good timing. View AVI Infoframe content.

Verify an HDMI Source’s Response to an EDID – Emulate the EDID of any HDMI sink device to verify that an HDMI source device responds properly to it. Store and retrieve multiple EDIDs for use in testing.

Verify Audio Data – Read the audio infoframes and audio sample packet headers including channel status bits from a connected HDMI source.

Check for CEC Devices – Poll an HDMI installation for CEC devices.

HDMI Cable and Link Test

Verify HDMI Cables – Run tests on HDMI 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 Networks with Repeater Test – Verify HDMI networks comprised of cables, audio/video extend- ers, 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 Networks with Frame Compare Test – Verify HDMI networks comprised of cables, audio/video extend- ers, switches, repeaters, etc. once installed. Test for pixel errors on the TMDS video.

HDMI Auxiliary Channel Analyzer (ACA) option

Emulation Monitoring of DDC Transactions – Monitor the HDCP and EDID transactions on the DDC while the 980 HDMI Video Analyzer is emulating a known-good source device, a known-good display device or both.

CEC Tester Application

Test CEC message handling capability of CEC devices – Run robustness tests or “irregular” tests on your CEC device using message with bit corruptions, timing variations. Also simulate irregular non-acknowledgement and arbitration scenarios.
