Synopsis

Excerpt from Evaluation, Revision and Application of the Nbs Stylus/Computer System for the Measurement of Surface Roughness

At a particular point in the stroke, the stylus arm activates a relay, which in turn generates two pulses. The first pulse, one second long, appears at the common input of the recorder and interface amplifier. (the source of the. Event pulse is in the information channel only for the duration of the pulse). Coincident with the leading edge of the event pulse is a fiftyemicrosecond interrupt pulse to the a/d converter. On receipt of the interrupt at the a/d, a programmed one - second delay is executed, and the analog signal at the filter output is convertedf to binary data points and stored sequentially in computer memory. (thus the event mark, recorded on the strip chart, does not appear in the digital data.)
