The ASNT_DMUX64 can be used for test applications, design verification, and R&D environments including double frequency rate NRZ data demultiplexing. The back panel of the instrument contains a power switch (Power), a power supply female connector (+9-12V DC) for connecting a male 2.5×5.5 barrel jack of the external AC-DC adapter, and an USB-B connector (USB) for connecting an external PC with installed Windows GUI control software. Two input data signals supplied through the CML differential ports are sampled by an internal clock that is derived form an input half-rate clock. The input clock has a controlled phase shift capability that allows for selection of the optimal data sampling point. The input half rate clock is divided by 2, and supplied to two outputs through; therefore, enabling a direct interface to an Error Detector. This feature simplifies measurements of the demultiplexed data. A Windows GUI (compatible with Windows XP, 7, 8 and 10) is used to control all adjustable parameters of the unit including demultiplexed data output amplitude, clock phase shift, common-mode voltage levels of the input clock signals, etc. The Unit is powered by a single 9V supply delivered from an external AC-DC adapter connected to the input socket on the back panel.
