|The main tool for writing acquisition software is the CASE
Artifex, by Artis Software. The output
code is standard ANSI C, and is compiled under Sun/OS® and
Solaris®. The processes involved in acquisition are
- VXI: controls the VXI acquisition boards
- SERVER MONITOR: it bounds the acquisition software to the monitor
and setup user interface
- COLLECT: it reads from various input ports the data and setup
parameters, format them into a frame, and send them to the
other processes and/or the analysis.
- DISK: it handles the data output to hard disk
- TAPE: it regularly frees disk space backing up the files to digital
tape (DLT cassettes)
- ANALYSIS: sends the data through an Ethernet connection to the
analysis workstation, where the data analysis software is running. It
is fault-tolerant for short (~few minutes) network interruption.
- GPIB: it handles the GPIB communication port to auxiliary
ERROR: it logs errors in the acquisition processes, and send warning
messages to the system operator.
