HDMI 2.0 compliance test software runs on Agilent scopes

January 15, 2014 // By Graham Prophet
Agilent Technologies has introduced two compliance test software packages for physical-layer testing of devices that use the new High-Definition Multimedia Interface (HDMI) 2.0 specification.

The transmitter compliance test software allows you to use Agilent Infiniium oscilloscopes to test HDMI 2.0 transmitters. Agilent’s receiver compliance software can be used with the company’s transition-minimised differential-signalling signal generator platform and the Agilent M8190A arbitrary waveform generator to test HDMI 2.0 receivers.

The HDMI 2.0 specification, published on 4 th September 2013, offers a significant increase in bandwidth (up to 18 Gbps) to support new features, better resolution and up to 32 audio channels.

Agilent’s HDMI 2.0 transmitter compliance solution builds on its HDMI 1.4b transmitter compliance test software that is currently used worldwide in HDMI-authorised test centres. The new software offers sophisticated capabilities now required for testing HDMI 2.0 transmitters, such as embedding standard cable models, de-embedding fixtures, providing reference equalisation and allowing engineers to characterise their systems using arbitrary models.

The HDMI 2.0 software improves usability by decreasing the number of “clicks to test.” Productivity improvements are enabled by two new software features: the ability to store and recall previous user set-ups, and test-plan control to guide users through all necessary tests for a given device, a capability previously lacking in HDMI solutions, Agilent says. Further increases in productivity are realised using a microwave switch matrix that allows all high-speed signals to be tested under control of the test software.

On the receive side, Agilent’s HDMI 2.0 receiver compliance solution is available as an upgrade for Agilent E4887A TMDS signal generators and the M8190A AWG. A new cable emulator allows existing E4887A customers to upgrade to the HDMI 2.0 receiver test solution.

The M8190A AWG solution offers a cost-effective and compact alternative to Agilent’s E4887A HDMI platform. The M8190A AWG setup eliminates switching between various cable emulators because waveforms are digitally synthesised to emulate the desired distortions. This capability reduces the manual reconfiguration effort and increases reliability. The AWG test solution reduces development costs while providing accurate test results with greater flexibility.
