Teledyne LeCroy 780 Offers

The quantumdata 780 are equipped with both a reference HDMI source and a reference HDMI sink interface allowing you to test audio, video and HDMI protocols—HDCP, EDID, CEC & infoframes—of any type of HDMI device: sources, repeaters and sinks.

You can use the 780 as pattern generators for calibrating your high definition TVs. The 780 are equipped with a variety of standard patterns and formats including deep color and HDMI 3D formats for routine video pattern testing and calibration of high definition and ultra high definition displays and TVs.

The 780's portability makes them ideal for your bench and for use in the field. A color touch display makes the 780 instruments easy and convenient to use and when testing a source device you can view the incoming video image and metadata on the built-in LCD.

Because the 780 test instruments have both HDMI output and HDMI input ports, you can test your HDMI cables and HDMI network with splitters, extenders and switches even when already installed on site using the Frame Compare feature.

Diagnose and Troubleshoot

The 780 model provide a status bar on the bottom of the touch screen. The status bar provides basic information about what the instrument is transmitting to a display and what it is receiving from a source. The instruments can run quick video audio and protocol tests on individual sources, displays, repeaters, distribution gear as well as cables. Protocol tests include tests for EDID, HDCP authentication, info frames and timing data. You can place the 780 at any point in a video distribution network and run tests upstream toward the sour while emulating a display (or sink). Or you can run tests downstream while emulating a source. Generator reports to demonstrate test series completion.

Ease of Use

The 780's color touch screen provides ease of use. The rich set of routine tests and diagnostic tests are accessible with just a few touch clicks. You can quickly configure settings on the outputs. A rich command set, available the USB port supports automated testing.

View Incoming Video and Data

The 780 status bar provides essential information about the incoming video. The Video Display Test shows the incoming video and essential video and audio meta-data. Both provide quick time-to-insight when conducting routine tests or diagnosing interoperability problems.

Test Response to EDIDs

Many interoperability problems are related to EDIDs. 780 enables you to emulate any EDID to test a source's response. You can use commercial EDIDs or test EDIDs with specific video and audio support. Test with EDIDs with known anomalies.

View Aux Chan Transactions

Complex interoperability problems require visibility into the auxiliary channel. You can monitor HDMI and HDBaseT Display Data Channel data to view EDID, HDCP and CEC transactions. You can check details of each transaction in the log and distribute the logs to colleagues.

Verify Cable/Network (Loop)

The 780 enables you to test distribution equipment to verify integrity of extenders, matrix switches and distribution amps. You can test individual devices or entire networks including video cables.

Verify Video at Far End

The 780 supports testing of installed distribution networks from the far-end at the display.

Verify Video

Select from CEA or VESA formats or create you own custom formats including 1080p resolutions with deep color for testing up to 225MHz. Use the test pattern library to verify specific video display elements. Set bit depth, pixel encoding, colorimetry and sampling parameters. Use industry standard patterns for color calibration. Create custom bitmap test patterns. Scroll bitmaps to test motion artifacts.

Verify EDID Contents

Many interoperability problems are related to EDIDs. You can view the EDID contents of any connected display to verify its audio/video capabilities. You can verify the structure of an EDID and check for compliance. Capture and EDID from a connected display and save it for future testing.

Verify Audio

You can use the 780 to verify audio on displays or audio systems using programmable LPCM test tones. Set sampling rate, bit depth, amplitude and number of channels. You can select Dolby and DTS compressed audio clips including Dolby TrueHD & DTS Master Audio.
