4K/UHD (12G/6G/3G) Test & Measurement
4K/UHD has led to a proliferation of new standards and formats, with delivery using quad-link 3G, dual link 6G or single link 12G signals. These higher bandwidth signals are more challenging to manage, and physical layer testing (Eye and Jitter) at facilities is especially important in view of the greater cable length sensitivity and unforgiving nature of these high-speed interfaces. As 12G-SDI continues to gather momentum for UHD applications, and many customers face a choice between SDI and IP infrastructure, there is a real need for informed and pragmatic decision making influenced by business values.
To address this requirement, PHABRIX has developed a class-leading suite of SDI analysis and stress tools that extend all the way up to UHD 12 Gbit/s that are available as an option for the Qx. Until now it has not been possible to thoroughly evaluate the behavior and performance of 6 and 12 Gbit/s SDI interfaces.
PHABRIX SOLUTIONS FOR UHD TEST AND MEASUREMENT
Qx SERIES – 12G PHYSICAL LAYER ANALYSIS
The Qx Series’ optional Physical layer Toolset offers the fastest 12G/6G/3G/HD-SDI physical layer testing, with its RTE™ (Real-Time Eye) Technology instantly highlighting any SMPTE compliance issues including eye amplitude, transition times and overshoot. Built in automation control allows testing to be performed faster, more reliably and at lower cost.
Qx SERIES – SDI STRESS TOOLSET
The advanced SDI-STRESS option is available for stress testing and R&D evaluations of SDI interfaces up to 12G. It includes the ability under automation control to insert SDI clock jitter, mute any of the SDI outputs, and control the SDI scrambler, sync-bit insertion, pre-emphasis, rise time and driver amplitude. The SDI-STRESS Eye amplitude measurement provides both Shorth mean and mode, with a histogram overlay and a user-defined window for the exploration of eye amplitude.
Qx SERIES – ADVANCED UHD/4K SUPPORT
The Qx Series 4K/UHD upgrade option offers support for an additional 36 UHD and 4K SDI formats for a wide range of post production and broadcast applications. Quad 1.5G and 3G, single 6G, dual 6G and single 12G interfaces at all frame rates including 48 and 49.97Hz are featured, as well as extended mode support for all color formatting including 4:2:2, 4:2:2:4, 4:4:4, 4:4:4:4 at 10 and 12-bits. All SDI link configurations fully support Levels A & B with square division and 2 sample interleave (2SI).
Qx SERIES – GENERATION AND PATHOLOGICAL DETECTOR TOOLSET
The Generator Toolset option provides not only the core full screen SDI Pathological stress patterns (Eq, PLL, Clk, checkfield and combined), but also allows the user to define a combination of the SDI stress and conventional generator patterns up to full frame. These patterns can be duplicated on all four SDI outputs.
An SDI Pathological Detector provides indication of the rate of generation of pathological conditions, and the detection of pathological conditions on each active SDI input with real time GPI output for external equipment triggering.
CASE STUDY: Radio Télévision Suisse selects PHABRIX’s Qx
Swiss public broadcasting corporation, Radio Télévision Suisse (RTS), part of SRG SSR, has purchased three of PHABRIX’s 4K and UHD-enabled Qx test and measurement solutions. TheQx rasterizers will be used for the technical validation of UHD signals and SMPTE-2110 measurements within RTS’ Test and Measurement laboratory and for its colour grading production suites.
