Represents automation control
Control represents the measured
test regardless of home control
amplification - called the filtered signal conditioning
into the computer called input channel
core is a computer

The development of measurement and control instruments and measurement and control system

1. The first generation Analog instrumentation
2. Second generation Digital Instruments
3. The third generation smart instrumentation
4. The fourth-generation virtual instrument based on the data acquisition card USB bus and PCI bus

Computer Control System of advantages

1. Zero automatic calibration
2. Automatic range switching
3. Fast multi-point measurement and control
4. Software filtering of the linearized
5. It may be complex data and complex process control law
6. Multimedia features
7. Communication or network capabilities
8. Self-diagnosis function
