QD780 Handheld Video Test Kit
The 780 handheld HDMI test instrument is a battery powered, portable multimedia pattern generator that enables you to conduct quick, on-site verification testing of your HDMI system and analogue video displays.
The 780 is equipped with both a reference source and a reference sink HDMI interface allowing you to test audio, video and protocols - HDCP, EDID, CEC & infoframes - of any type of HDMI device: sources, repeaters and sinks. You can test and calibrate your high definition TVs with a variety of standard patterns and formats including deep colour and HDMI 1.4a 3D. Its portability makes it ideal for your bench and for use in the field. Because the 780 has both an HDMI output and an HDMI input, you can test your HDMI cables and systems with splitters, extenders and switches as well with the optional pixel error rate test feature.
A colour touch display makes the 780 easy and convenient to use and when testing a source device you can view the incoming video on the built in LCD.
You can monitor the DDC transactions, hot plug events and CEC messages using the 780's (optional) Auxiliary Channel Analyzer feature.
See all of the 780's applications depicted in the 780 data sheet.
Standard Features (included with all options)
- Battery powered for portability. Device is powered via internal batteries or externally via an AC charger.
- Video pattern testing. Test a display's HDMI and analogue component inputs to ensure that it can render video test patterns including deep colour and HDMI 1.4a 3D patterns. Over 25 video patterns supported. Add custom bitmaps. Scroll bitmap patterns to test for motion artefacts.
- 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, Dolby, and DTS.
- Confidence test of an HDMI source. Emulate a known-good HDMI sink device to test video and audio content from an HDMI source device with HDCP content protection. View the incoming video from a source device on the LCD display even when content is protected with HDCP.
Network Analyzer Option
- 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.
- Verify 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 a verification test on the EDID of a sink device such as an HDTV or input of a repeater device. Check the contents of the EDID of the sink device.
- Verify an HDMI source's response to an EDID. Emulate the EDID of any HDMI sink device to check how an HDMI source device responds to it.
- 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 Option
- Test 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.
- Test HDMI networks. Run tests on HDMI networks comprised of cables, audio/video processors, extenders, switches, repeaters, etc. Test for pixel errors on multiple formats (resolutions) on the TMDS video and check continuity on the 5 volt, hot plug and DDC lines.
HDMI Auxiliary Channel Analyzer (ACA) option - Two options available
- 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 the 780 is emulating a known-good source device, 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 the 780 is passively monitoring an HDMI system comprised of multiple devices.
