Abstract
Abstract Provided is an oscilloscope-like user-interface for a logic analyzer. The oscilloscope-like user-interface simplifies user control of the logic analyzer. The oscilloscope-like user-interface substitutes two oscilloscope-like controls (seconds-per-division and delay) for six logic analyzer controls (sample-period, magnification, magnify-about, magnify-about marker-movement, start/center/end, and delay-from-trigger). The result of the substitution is a logic analyzer which is operable with oscilloscope-like controls and which does not require user understanding of the logic analyzer's sampling hardware for effective user operation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
A user-interface for a logic analyzer, the user interface having an oscilloscope-like knob, said knob being controllable by the user for continuously adjusting variables on a scale, the user-interface being part of the logic analyzer, said logic analyzer having a waveform display window and a waveform trace memory, said user-interface comprising: a seconds-per-division control, being part of the logic analyzer, such that through direct access using the knob, the user can continuously adjust and control magnification of the waveform display window of the logic analyzer solely by altering the seconds-per-division control such that increasing the ratio of seconds-per-division decreases magnification and decreasing said ratio increases magnification; and a delay control, being part of the logic analyzer such that through direct access using the knob, the user can control the position of the waveform display window of the logic analyzer relative to the waveform trace memory of the logic analyzer solely by altering the delay control.
Claim 2
Dependent Claim
155 words
A user-interface for a logic analyzer, the user interface having an oscilloscope-like knob, said knob being controllable by the user for continuously adjusting variables on a scale, the user-interface being part of the logic analyzer, said logic analyzer having a waveform display window and a waveform trace memory, said user-interface comprising: a seconds-per-division control, being part of the logic analyzer, such that through direct access using the knob, the user can continuously adjust and control magnification of the waveform display window of the logic analyzer solely by altering the seconds-per-division control such that increasing the ratio of seconds-per-division decreases magnification and decreasing said ratio increases magnification; and a delay control, being part of the logic analyzer such that through direct access using the knob, the user can control the position of the waveform display window of the logic analyzer relative to the waveform trace memory of the logic analyzer solely by altering the delay control.
Claim 3
Dependent Claim
151 words
A user-interface for a logic analyzer, the user-interface being part of the logic analyzer, said logic analyzer having a waveform display window and a waveform trace memory, said user-interface having an oscilloscope-like user control which makes said analyzer operable like an oscilloscope, said user-interface comprising: a seconds-per-division control, being part of the logic analyzer, such that through direct access by the user control, the user can continuously adjust and control magnification of the waveform display window of the logic analyzer solely by altering the seconds-per-division control such that increasing the ratio of seconds-per-division decreases magnification and decreasing said ratio increases magnification; and a delay control being part of the logic analyzer such that through direct access by the user control, the user can control the position of the waveform display window of the logic analyzer relative to the waveform trace memory of the logic analyzer solely by altering the delay control.
