The data acquisition system is designed on embedded PC104 platform Single Board Computer (SBC) with running Windows XP Embedded operating system. This is a multi channel system which consists of 12 Bit, 10 MSPS Analog to Digital Converters with on board FIFO memory for each channel. The digital control and PC104 bus interface logic are implemented using Very High Speed Hardware Description Language (VHDL) on Complex Programmable Logic Device (CPLD). The system has provision of software, manual as well as isolated remote trigger option. The Client Server based application is developed using National Instrument CVI for remote continuous and single shot data acquisition for basic plasma physics experiments. The software application has features of remote settings of sampling rate, selection of operation mode, data analysis using plot and zoom features. The embedded hardware platform can be configured to be used in different way according to the physics experiment requirement by different top level software architecture. The system is tested for different physics experiments. The detailed hardware and software design, development and testing results will be discussed in the paper.

We have developed special instrumentation for spectroscopy diagnostics of the SST-1 Tokamak. Light output in the visible spectrum is guided through fiber optics from the Tokamak ports to the diagnostics Hall, where photo multipliers tubes and other instrumentation electronics are kept. High Voltage(0 - 1500 V) bias generation electronics is required to bias these PMTs. Total 14 PMTs to be biased for overall requirements of the diagnostics. We have developed modular electronics for HV bias generation, which consist of one controller and seven HV modules. We have designed and developed FPGA based controller card which controls seven HV modules. The Slot-0 card is having Spartan 3E FPGA and Standalone Controller Area Networking (CAN) controller. 32-bit RISC processor Microblaze has been deployed into the FPGA. We have used Hitek make HV supply modules which is programmable. In the HV modules, Analog Device Inc. make iCoupler, digital isolators are used to break the ground loops and to avoid ground-lifting problem. Various features like Manual mode/Remote mode operation, HV ON/OFF, HV Value setting through remote GUI have been developed on LabVIEW software.
