Once activated, the real-time task will acquire data from a digital input/output board at a frequency of 10kHz. The Ch script will acquire a certain number of data points as set below. Once all of the data points have been acquired, script will create a plot of the acquired data using the plotting class avaiable under Ch. The plot will then be displayed through the browser using the CGI capabilities of Ch. </TD></TR> <TR><TD> <HR> </TD></TR> </TABLE> </BODY> </HTML>
