The TAG 'Engineering bundle' (Order reference PHSXO-ENGT) if purchased on a new SxTAG unit, offers a discount of approximately 40% over the collection of options offered. This is ideal for customers who wish to purchase all the options as part of a single deal. The SDI analysis option provides the engineer with a detailed view of the data words contained within the SDI stream. The Command scripts with print report option allows a series of pre-defined actions such as controlling the generator, analyser and logging functions. The Programmable moving zone plate option can be used to test a range of video processing requirements using horizontal, vertical and temporal (time) controls. The Dolby bit-stream Analyzer option displays Dolby E, Dolby Digital and Dolby Digital Plus metadata present in a selected audio stream and determines whether the Dolby E packet is timed correctly on the SDI video stream. The Dolby bit-stream generator option uniquely adds significant Dolby E, Dolby Digital and Dolby Digital Plus metadata generation features to the Sx range. The Enhanced remote control option allows full remote control of the instrument via TCP/IP Sockets to allow any aspect of the unit to be modified or queried.
