And Storage

We have automated a Seeman-Bohlin Guinier x-ray diffractometer by interfacing it to a minimally configured PDP 11/23 computer. The programs that run on the microcomputer to control the operation of the diffractometer are stored on a mainframe host running the UNIX+ operating system. A software interface allows a particular data acquisition program to be downloaded from the UNIX host and executed on the satellite processor. This same interface allows the collected data to be periodically off-loaded to the host for processing and storage.

Data Acquisition Program

To sample wideband IF signal with large amounts of data, a high-speed data acquisition program is presented. The program focus on circuit design, issues that need attention, and high-speed sampling signal deceleration strategy. The 2.4GHz rate sampling data acquisition, reception and demux are completed with ADC083000 and Field-Programmable Gate Array (FPGA). At last, a result of sampling with the converter is offered by chipscope software. The result verified ADC083000 has an excellent performance with more than 6.5 bit ENOB and good phase coherence. In engineering practice, the design has been used and has good performance.
