The DAQ970A and DAQ973A data acquisition systems are high-performance modular instruments from Keysight Technologies, with typical applications spanning multiple fields:
1. Industrial Manufacturing and Automated Testing
       •  Production Line Monitoring: Real-time monitoring of parameters such as temperature, pressure, and current on production lines to ensure process stability. For example, used in automotive manufacturing for engine performance testing, chassis dynamometer inspection, and electronic system evaluation.
       •  Component Inspection: Screening, aging testing, and fault diagnosis of electronic components — such as monitoring soldering temperatures on circuit boards or analyzing power voltage fluctuations.
       •  Quality Control: Achieve automated testing through multi-channel independent configuration (e.g., thermocouples, RTDs, voltage measurements), improving product consistency.

2. Energy, Power, and New Energy Systems
       •  Power Generation Equipment Monitoring: Collects parameters such as temperature, voltage, and current from generators, transformers, and other equipment in power plants and substations, supporting predictive maintenance.
       •  New Energy System Management: Monitors PV panel efficiency, wind turbine operating status, and grid connection parameters in solar and wind farms.
       •  Power System Fault Diagnosis: Locates grid anomalies using high-precision measurements (e.g., 0.003% DC voltage accuracy).

3. Scientific Research and Education
       •  Multi-Disciplinary Experiments: Captures dynamic data in physics, chemistry, and biology experiments — such as temperature changes during chemical reactions or bioelectric signals.
       •  Educational Applications: Used in experimental teaching for electronics and automation majors to help students understand the principles of data acquisition and analysis.
       •  Material Characterization: Studies new material properties through measurements of parameters like stress and capacitance.

4. Medical Devices and Clinical Monitoring
       •  Medical Instrument Calibration: Tests performance parameters of devices such as sphygmomanometers and ECG machines to ensure accuracy.
       •  Patient Physiological Data Acquisition: Real-time monitoring of vital signs such as body temperature, heart rate, and blood oxygen levels, supporting telemedicine and health management.

5. Environmental Monitoring and Industrial Safety
       •  Weather and Pollution Monitoring: Collects data such as air temperature, humidity, and pollutant concentrations for environmental quality assessment and early warning systems.
       •  Industrial Emission Monitoring: Tracks key parameters in wastewater and exhaust emissions (e.g., pH value, particulate concentration) to ensure compliance with regulatory standards.

Technical Advantages Enabling Application Scenarios
       •  Modular Expandability: Supports flexible configurations from 4 to 120 channels, and can integrate actuators, digital I/O modules, and more to meet complex requirements.
       •  High Precision and Reliability: 6½-digit resolution, 0.003% DC voltage accuracy, and non-volatile memory (up to 1 million readings) ensure accurate and reliable data capture.
