Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test and measurement devices face challenges in effectively detecting and triggering on signal events due to imprecise and difficult-to-configure triggering methods, which limit the ability to identify and capture signals of interest.
Innovation Solution
A system and method for graphically actuating a trigger in test and measurement devices, where a visual representation of signal properties is displayed, and users can designate a portion of the representation to configure the trigger parameters, allowing for intuitive and automatic setup of triggers based on observed signal phenomena.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional triggering methods are used, then the device can detect signal events, but the triggering is imprecise and difficult to configure
Solution Approach 1:
The patent creates a visual copy of the signal waveform on display, allowing users to interact with a graphical representation rather than abstract parameters. Users can directly manipulate the visual waveform to set trigger points, which are then translated into actual trigger parameters, making configuration intuitive and precise simultaneously
Solution Approach 2:
The visual display serves as an intermediary between the user and the trigger configuration system. Instead of directly configuring numerical parameters, users interact with the visual representation, which automatically translates their selections into precise trigger settings, resolving the contradiction between ease of use and precision
2Adaptability or versatility
If manual parameter configuration is used, then trigger settings can be adjusted, but it requires significant time and effort
Solution Approach 1:
The system performs automatic parameter extraction and configuration based on user interactions with the visual display. When users select regions or features on the displayed waveform, the system automatically calculates and configures the appropriate trigger parameters, eliminating manual configuration steps while maintaining full adaptability
Solution Approach 2:
The system pre-processes the signal data to create the visual representation and pre-calculates potential trigger parameters based on displayed features. This preliminary preparation allows users to quickly configure triggers by simply selecting from pre-computed options rather than manually adjusting parameters from scratch
3Adaptability or versatility
If existing triggers are used, then basic signal events can be detected, but complex signal situations cannot be effectively detected
Solution Approach 1:
The visual trigger configuration system provides a universal interface that can handle multiple types of signal events and triggering scenarios through a single consistent interaction model. Whether detecting simple threshold crossings or complex patterns, users interact with the same visual display mechanism, making the system both versatile and reliable across different signal situations

AI summary
A system and method are provided for graphically actuating a trigger in a test and measurement device. The method includes displaying a visual representation of signal properties for one or more time-varying signals. A graphical user input is received, in which a portion of the visual representation is designated. The method further includes configuring a trigger of the test and measurement device in response to the graphical user input, by setting a value for a trigger parameter of the trigger. The set value for the trigger parameters varies with and is dependent upon the particular portion of the visual representation that is designated by the graphical user input. The trigger is then employed in connection with subsequent monitoring of signals within the test and measurement device.
