by a user over a desired portion of the signal waveform. The magnified
portion of the signal waveform is displayed at a location proximate to the
position of the selected waveform portion before magnification, thereby
enabling viewing of the magnified waveform portion within the context of
the entire waveform. (Specification 5-6).
Claim 1 is illustrative of the invention and reads as follows:
1. An instrument for collecting data and which displays the data to a
user, comprising:
a memory for storing data corresponding to a signal waveform; and
a display which displays the data as the signal waveform, wherein said
display is also operable to display a virtual magnifying symbol;
wherein the virtual magnifying symbol is operable to be positioned
over a portion of the signal waveform;
wherein the portion of the signal waveform is located at a first
location in the signal waveform;
wherein the portion of the signal waveform is magnified on the
display after positioning the virtual magnifying symbol over the portion of
the signal waveform;
wherein the magnified portion of the signal waveform is displayed
proximate to the first location in the signal waveform.
