PHABRIX has started shipping its new platform for UHDTV – the Qx for test and measurement, which is focussed on compliance verification for UHDTV1/4K and UHDTV2/8K standards. It is aimed at manufacturers of products requiring both an analysis and generation toolset – essential for product testing at these new high bandwidth standards. At NAB 2016, PHABRIX also presented its patented physical layer analysis for signals up to 12Gbps packaged under the trademark, RTE or ‘real time eye’ on the Qx.
The Qx displayed at NAB was available in two versions, one with the RTE technology for physical layer analysis and one without. Each supports up to a 48Gbps payload with four separate 12Gbps input and outputs.

PHABRIX also showed updates to both its portable and rackmount instruments at the event. The PHABRIX SxE was available with discounts on a bundled engineering option. The PHABRIX multi interface TAG with its complete solution from analogue to 3G-SDI with SFP support for optical has a new HDMI EDID viewer SFP option and an HDMI generator SFP.

The Rx rackmount is presented with PHABRIX’s dedicated toolset for quality control, OB support and broadcast engineering bays featured on the stand. With the release of version V9.04 software at NAB, the Rx demonstrated enhanced closed caption monitoring and signal line detect tools.

Paul Nicholls marketing director of PHABRIX explained that the need for compliance testing for UHDTV in the broadcast industry requires that specific measurements are taken as part of a product’s release. In the SMPTE standards these include eye amplitude, overshoot, undershoot, rise time and fall time with timing and alignment jitter readings. He stated that the Qx provides these readings automatically from the real time eye, there is no processing within the chip set, the signal is displayed ‘live’ for accurate T&M’. The bandwidth of the data being analysed at 12Gbps is immense, hence the Qx represents a very cost effective solution compared to a high end oscilloscope.
