Solution Overview
Problem
Existing measurement devices and methods lack the combination of high accuracy and efficiency, particularly in digital triggering techniques which are inefficient due to additional sample values required for interpolation and are limited to use across multiple input channels.
Innovation Solution
A measurement device with a trigger unit that receives input signals and triggers based on multiple conditions, including protocol data patterns, utilizing a digitizer, acquisition memory, detector, and display or audio output to enhance accuracy and efficiency, and a method that includes receiving input signals and triggering according to predefined conditions for improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital triggering is performed by carrying out level comparison and interpolation to determine triggering instant, then measurement precision is improved, but productivity deteriorates due to additional sample values required
Solution Approach 1:
The patent pre-calculates and stores trigger decision information (trigger/not-trigger determination) for multiple future time points in advance. This allows the trigger decision to be made quickly by simply reading the pre-computed result at the current time point, rather than performing interpolation calculations in real-time, thus resolving the contradiction between precision and efficiency.
2Adaptability or versatility
If OR-triggering is used across multiple input channels, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal trigger decision unit that processes trigger conditions for multiple channels using the same computational logic. The unit evaluates OR-trigger conditions across channels by reading pre-computed trigger decision information, enabling multi-channel adaptability without requiring separate complex processing paths for each channel.
