The 780 handheld test instruments for HDMI are battery-powered, portable video and audio generators and HDMI analyzers that enable you to conduct quick, on-site verification testing and troubleshooting of your HDMI system and analog video displays. The 780 series instruments 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.
The 780 supports HDMI testing at pixel rates up to 165MHz and TMDS rates up to 225MHz for deep color on the output and pixel rates up to 150MHz on the HDMI input.
Standard Features (included with all options):
- Battery powered for portability, Device is powered via internal batteries or externally via an AC charges.
- Video Pattern Testing. Test a display's HDMI and analog component inputs with all the necessary standard timinings to ensure that it can render video test patterns including deep color and HDMI 3D patterns. OVer 25 video patterns supported. Add customer bitmaps. Create your own custom formats. Scroll bitmap patterns to test for motion artifacts.
- HDMI audio testing. Send audio patterns, tones & noise through HDMI , SPDIF or Optical digital audio outputs. Program audio parameters such as a sampling rate, bit depth and channels. Use a variety of audio formats including LPCM, Dolby, DTS and high bit rate audio formats such as Dolby TrueHD and DTS Mater Audio.
- HDMI analyzer for source. Emulate a known-good HDMI sink device to analyze HDMI video and audio content from an HDMI source device HDCP content protection. View the incoming video images and metadata from an HDMI source device on the LCD display even when content is protected with HDCP.
- Installer Utility; Quickly diagnose HDMI interoperability problems through an automated and simplified interface. Run test upstream toward the source, downstream toward the sink or test both upstream and downstream simultaneously with the "link" test. The utility also enables you to test on both sides of a repeater.
Other Options (Not Included):
HDMI Network Analyzer (Optional)- Verify HDCP on repeaters and displays. 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.
- Check Max HDCP HDMI devices. Check the number of HDCP devices on HDMI source supports during HDCP authentication.
- Verifiy video timing. Verify the timing of an HDMI source. Compare against a known-good timing,
- Verify video type. Verify the video type of an HDMI source. VIew AVI infoframe content.
- Identify EDID problems. Run verification tests on the EDID of a sink Device. Run portions of the EDID compliance test, Compared two EDIDS.
- Verify an HDMI source's response to an EDID. Emulate the EDID of any, HDMI signk 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 & Link Test Options- Verify HDMI cables. Run tests on HDMI cables. Test for pixel errors on multiple formats (resolutions) on the TMDS video and check continutiy on the 5 volt, hot plug and DDC lines.
- Prequalify HDMI 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 networks (once installed) with Frame Compare test. Verify HDMI networks comprised of cables, audio/video processors, extenders, switches, repeaters, etc. once installed, Test for pixel errors on the TMDS video.
HDMI Auxilary: Channel Analyzer (ACA) option - Two options avaiable. - Option 1 - Emulation monitoring of DDC transactions and hot plug events. Monitor the HDCP and EDID transactions on the DDC and also monitor hot plug related events while -80 is emulating a known-good source devices, a known-good display device or both.
- Option 2 - Passive monitoring of DDC transactions and hot plug events (includes emulation monitoring option). Monitor the HDCP and EDID transactions on the DDC and also monitor hot plug related events while -80 is passively monitoring and HDMI system comprized of multiple devices. REquires an additional hardware module with four (4) additional HDMI ports.
Custom Bitmap Test Pattern Pack Options- China Res Test Pattern Package - The CinaTes test pattern is specified by the National Testing and Inspection Center for radio and TV Products of China. The image pack includes both a standard definition aspect ration (shown right) and a high definition aspect ratio. This test pattern is supported at 1920x1080, 720x576 and 720x480 resolutions.
- THX, LTD. Test Pattern Package - The THX test patterns enable A/V professionals to calibrate the displays on high-end 3D capable HDTVs to match the same standards as those used in post-production facilities worldwide. Below are some of the THX test patterns included:
- 3D convergence - test patterns to align pixels for proper convergence.
- 3D crosstalk - test patterns to determine level of 3D crosstalk.
- Color gamut - 2D/3D primary & secondary color patterns to fine-tune colors & gamma.
- Picture performance - pattern within THX Optimizer to verify accuracy of skin tones.
- THX box - 2D/3D grayscale test patterns to accurately adjust white point and gamma
- THX Optimizer - test patterns to easily adjust brightness, contrast, color, tint, etc.
- Uniformity - 2D/3D circle patterns to determine luminance & chrominance screen uniformity
Imaging Science Foundation (ISF). Test Pattern Package - The ISF test patterns enable A/V professional to calibrate the displays on moderm high-end HDTV's.
Below are some of the ISF test patterns included.
- Geometry - for testing geometry and resolution parameters
- White Pluge - for calibrating white level for dynamic range
- Black Pluge - for calibrating black level for dynamic range
- Red-Blue Color Multiburst - measures chroma resolution by identifying the maximum frequency individual lines can be discerned

Features
- You can use the 780/780A instruments as a pattern generator for calibrating your high definition TVs. The 780s are equipped with a variety of standard patterns and formats including deep color and HDMI 3D formats.
- Because the 780/780A series instruments have both HDMI output and HDMI input ports, you can test your HDMI cables and systems with splitters, extenders and switches even when already installed on site using the Frame Compare feature.
- The 780/780A series instruments can also be equipped with the optional Auxiliary Channel Analyzer (ACA) utility for monitoring the DDC (HDCP and EDID) transactions and hot plug events.
- There are two ACA options, one for monitoring while emulating an HDMI source and/or sink and a second option for monitoring passively an HDMI network comprised of an HDMI source, repeater and sink. The passive monitoring option requires an extra hardware board with 4 HDMI ports.
The 780s' 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.
