Solution Overview
Problem
Conventional production testing of wireless communication systems is time inefficient due to sequential control of the device under test, limiting the speed of data acquisition and analysis.
Innovation Solution
A system that includes a testing module, a measurement module, and a control module, which allows for simultaneous acquisition and analysis of test data by initiating multiple test sequences independently, enabling multitasking and increased time efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the computer controls the DUT in a sequential manner, then the control is simple and easy to implement, but the testing time is extended and time efficiency is reduced
Solution Approach 1:
The control module initiates multiple test sequences in advance before the analysis system has finished analyzing previous test data. The testing module transmits test signals based on these pre-initiated sequences, allowing test data acquisition to proceed concurrently with data analysis, thereby reducing idle waiting time while maintaining controlled operation
Solution Approach 2:
The system maintains continuous test data acquisition by initiating second and subsequent test sequences while the analysis system is still analyzing data from previous sequences. This eliminates idle periods where the testing module would otherwise wait for the analysis system to complete its work, ensuring continuous productive operation of the testing apparatus
2Measurement precision
If the computer waits for data analysis to complete before initiating the next test, then data analysis accuracy is ensured, but productivity is reduced
Solution Approach 1:
The system divides the testing process into independent, parallel test sequences that can be initiated and executed separately. The control module manages multiple test sequences independently, allowing the analysis system to process data from one sequence while the testing module simultaneously acquires data from another sequence, thereby maintaining both accuracy and productivity
Solution Approach 2:
Test sequences are preliminarily initiated and configured in advance by the control module, so that when the analysis system finishes analyzing previous data, new test data is already being acquired or ready for analysis. This preliminary preparation of test sequences enables continuous processing without compromising analytical accuracy
3Loss of time
If multiple test sequences are initiated simultaneously, then time efficiency is improved, but device complexity increases
Solution Approach 1:
The control module is designed with multi-functionality to manage both sequential and parallel test sequences using the same hardware components. It can initiate multiple test sequences, transmit test signals, and coordinate with the analysis system without requiring separate dedicated hardware for each function, thereby reducing overall system complexity while enabling parallel operation

AI summary
A system for testing a communication device includes a testing module, a measurement module, and a control module. The testing module transmits one or more first test signals based on a first test sequence. The measurement module acquires test data by receiving one or more second test signals that are based on the one or more first test signals. The control module initiates the first test sequence in response to receiving a start test signal from an analysis system. The control module transfers the test data to the analysis system in response to a transfer data request. The control module initiates a second test sequence while the analysis system is analyzing the test data. The testing module generates and transmits one or more third test signals based on the second sequence when the second test sequence has been initiated.
