1Measurement precision
If manual configuration of measurement parameters is performed, then measurement precision can be optimized, but setup time increases and operation complexity increases
Solution Approach 1:
The measurement application device automatically determines and configures measurement parameters (resolution bandwidth, video bandwidth) based on the incoming signal characteristics, eliminating the need for manual user configuration. The device serves itself by autonomously optimizing settings according to the actual measurement task requirements.
Solution Approach 2:
The system dynamically adjusts measurement parameters based on the detected signal level. When a signal is received, the device changes the resolution bandwidth and video bandwidth parameters automatically to match the signal characteristics, thereby optimizing measurement precision without manual intervention.
2Measurement precision
If manual configuration of measurement parameters is performed, then measurement precision can be optimized, but operation complexity increases
Solution Approach 1:
The measurement application device automatically determines and configures measurement parameters (resolution bandwidth, video bandwidth) based on the incoming signal characteristics, eliminating the need for manual user configuration. The device serves itself by autonomously optimizing settings according to the actual measurement task requirements.
Solution Approach 2:
The device performs preliminary analysis of the incoming signal to determine appropriate measurement parameters before actual measurement begins. This preliminary action of detecting signal characteristics and pre-configuring parameters simplifies the overall operation and eliminates manual setup complexity.
3Measurement precision
