Overview
Use the DVI and HDMI analyzer option to test HDMI 1.3 deep color source products, such as set-top boxes, DVDs as well as repeaters and cables. Source product manu- facturers will find this option invaluable for verifying signal quality, timing, color encoding, and E-EDID/E-DDC/HPD- related behavior.
The analyzer option adds a digital video receiver to the base instrument. This receiver emulates a sink device (display), while the generator output emulates a source (host) device. The receiver presents an on-the-fly repro- grammable E-EDID to the source, and analyzes incoming video for data errors and timing anomalies. The receiver can analyze video from the instrument itself or from an external source. Results can be displayed on the instru- ment’s front panel or issued as formatted reports.
The HDMI and DVI analyzer option passes through the incoming digital signal to the HDMI Tx interfaces, which can be connected to a HDMI display for monitoring incoming content. The displayed image rendered identically as the source on a pixel per pixel basis. The analyzer also routes incoming audio to a SPDIF output, which can be connected to an external digital speaker or audio analyzer.
Signal quality can be measured without meticulous inspection of a display screen. The analyzer accepts stan- dard QDI-BCM pseudo-random noise test patterns, which allow overall signal quality to be measured and expressed in simple objective terms. In cases where the analyzer is connected to a video source that does not support the rendering of pseudo-random noise data, a pixel error measurement technique can be alternately used, which counts flickering pixels in still-frame test images. Detailed pixel-by-pixel analysis is also supported for checking color encoding, scaling, and masking in test images.
Timing can be measured, independent of video content. The signal analyzer manager can be used to check sever- al timings and obtain HTML report.
The analyzer option is also excellent for finding problems with repeaters, cables, cable extenders, and distribution systems. Everything needed to test transmission systems from end-to-end, using pseudo-random noise or test images, is now available in a single instrument.
The analyzer optionally supports CEC compliance testing with the Test Management Environment (TME). The TME application is used for testing CEC compliance in the HDMI Authorized Test Centers.
The analyzer optionally supports HDCP compliance testing enabling developers of HDMI products to perform fast, comprehensive HDCP compliance test. on sources, sinks or repeaters, in accordance with the HDCP compliance test specification.
