On-going Development
PHABRIX is committed to developing the toolsets on the Qx. There will be upgrades which will include
improvements to existing instruments and the addition of new ones.
Please do not hesitate to contact PHABRIX at any time to discuss your requirements for the product or to
discuss the current product time-line.

Automatic measurement provided by Qx
The complexity of both analyzing and generating signals for UHDTV is exemplified above. The data
bandwidth testing from HD through to UHDTV at 12Gbps, standard on the Qx, is immense and the
parameters set by SMPTE require that the instruments measure these critical values for compliance.
