Spectrum Analyzer Frequency Marker Position Setting via Direct Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing spectrum analyzers, setting the position of frequency markers requires complex operations involving multiple function menus and physical encoders, leading to a high workload for users.
Innovation Solution
A spectrum analyzer with a simplified user interface that allows for efficient setting of frequency marker positions through a graphical display, enabling users to input desired frequencies directly within a frequency indication frame or move the marker along the frequency axis, without needing to open additional screens or use physical encoders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional method of setting frequency marker position using multiple function menus and physical encoders is used, then the frequency marker can be positioned, but the user workload becomes excessively high and operation becomes complex
Solution Approach 1:
The patent combines the frequency marker display and position setting functionality into a single integrated display screen. The frequency indication frame serves dual purposes: displaying the current frequency value and accepting direct user input for position setting. This eliminates the need for separate function menus and physical encoders, resolving the contradiction by merging multiple operations into one unified interface.
Solution Approach 2:
The frequency indication frame becomes self-service by directly accepting user input (e.g., keyboard input) to change the marker position. The system automatically updates the marker position based on the input frequency value without requiring the user to navigate through multiple menus or operate physical encoders. This self-service mechanism significantly reduces user workload and operational complexity.
2Productivity
If direct frequency input is allowed in the frequency indication frame, then the setting operation is simplified, but the display interface must handle additional input states
Solution Approach 1:
The frequency indication frame dynamically changes its display mode based on the current operation state. It can switch between display-only mode and input-enabled mode, with visual indicators showing whether the frame is ready to accept input. This dynamic behavior allows the interface to handle multiple states (normal display, input ready, input in progress) without requiring separate physical controls, thereby improving productivity while managing interface complexity through state-based design.

AI summary
A spectrum analyzer includes: a spectrum display control unit that displays a graph showing a spectrum characteristic, a frequency marker, and a level marker on a spectrum display screen; an input-enabled state display control unit that displays a frequency indication frame in an input-enabled state, in response to an operation of selecting the frequency marker via a keyboard; and a marker position setting display control unit that receives input of a desired frequency to the frequency indication frame in a case of the input-enabled state, changes a position of the frequency marker on a horizontal axis (frequency axis) to a position of the input frequency, and updates a value of a frequency indicated by the frequency indication frame to a value of the input frequency to display the updated value.
