WSR-120A Wideband Overhead Card for WDAU with Optional CAIS Interface

The WSR-120A is a high-speed overhead card for use in the WDAU-20XX product family. The card enables the WDAU to operate as a wideband, stand-alone data acquisition unit with maximum bit rates up to 20 Mbps. The system works with I/O cards that are compatible with high-speed operation. The unit can also simultaneously operate as a CAIS remote slave unit.

The WSR-120A can be used along with the optional WSR-120D card in the same WDAU chassis to provide operation as a CAIS remote slave unit for programming, data selection and synchronization, in addition to stand-alone operation. The WSR-120A also provides IRIG-B time code capability to the WDAU.
