Method for displaying a plurality of traces calculated from a plurality of input signals obtained device for continuously displaying measurement values, and a plurality of trace

摘要

A method of displaying continuously acquired measurement values as a plurality of traces in a display with a fixed number of pixels is provided. An input signal is captured as a series of acquired input signals. Measurement values are calculated from the acquired input signals according to a set of measurement parameters. The measurement values are plotted to a display as a plurality of traces according to the measurement parameters. Each of the traces may be scaled vertically independently of one another. At the end of the fixed number of pixels of the display, the pixel values are compressed to half the fixed number of pixels and the pixel rate is halved, thereby doubling the time scale. As a minimum pixel rate is eventually reached, the traces are then scrolled in a roll mode in which the newest measurement value is added to one end of the display and the old value at the other end is discarded. This scrolling process can continue indefinitely, requiring no operator intervention or prior knowledge to set a total measurement time.
