Solution Overview
Problem
Sophisticated test equipment for communication systems, with increased processing power, becomes cumbersome for remote and multi-user access due to complex interfaces and data processing requirements.
Innovation Solution
A distributed test equipment system utilizing a packet-switched network to relay packetized test commands and signal data between analog signal receivers and computers, allowing remote control and processing of analog signal data, thereby separating the user interface from the test equipment and moving processing to client computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If processing power and sophistication are increased within the test equipment, then measurement and analysis capabilities are improved, but device complexity and difficulty of remote access increase
Solution Approach 1:
The system divides functionality into separate components: the test equipment (receiver) handles signal measurement and data collection, while the computer handles processing, analysis, and user interface operations. This segmentation allows each component to be optimized independently - the receiver remains simple while the computer provides sophisticated processing capabilities.
Solution Approach 2:
The user interface and data processing functions are extracted from the test equipment and moved to a separate computer system. This extraction eliminates the complexity of incorporating sophisticated processing capabilities within the receiver, while still enabling advanced signal analysis through the connected computer.
2Adaptability or versatility
If processing power is increased within the test equipment, then stand-alone utility is improved, but ease of remote access deteriorates
Solution Approach 1:
By segmenting the system into a simple receiver and a versatile computer, the invention enables both stand-alone operation (receiver can function independently for basic measurements) and remote access (computer provides sophisticated interface and processing capabilities over a network).
Solution Approach 2:
The computer acts as an intermediary between the user and the test equipment. It provides the sophisticated user interface and processing capabilities while communicating with the simple receiver through standardized network protocols, thereby facilitating easy remote access without requiring the receiver itself to be complex.
3Measurement precision
If sophisticated processing capabilities are integrated into the test equipment, then analysis capability is improved, but number of users that can access simultaneously deteriorates
Solution Approach 1:
The processing and analysis capabilities are extracted from the receiver and placed in the computer system. This allows multiple users to access the same receiver simultaneously through the computer network, each performing their own signal analysis operations without interfering with the receiver's ability to service multiple clients.
Solution Approach 2:
The computer system provides universal access to the receiver for multiple users. It can simultaneously serve multiple clients, each with their own user interface and processing requirements, while the receiver maintains a single simplified interface for data collection and measurement.
Data Source
AI summary
A distributed test equipment system for testing analog communications systems. One or more analog signal receivers and one or more computers are connected via a packet-switched network such that each computer can remotely control and receive signal data from each receiver. Analog signal data measured by each receiver is available for relaying to each computer where it is processed for analysis in conformance with respective user commands.
