GE DS3800NATD Analog Test Card

The primary function of the DS3800NATD is to provide a means to test and verify the analog circuitry within the Mark IV control system. Analog signals are crucial for measuring continuously varying physical parameters like temperature, pressure, and vibration. The test card is used by technicians to:

  • Simulate Signals: It can generate analog signals to simulate sensor inputs, allowing technicians to test the system’s response without a live sensor. This is essential for troubleshooting and calibration.
  • Signal Verification: It provides test points and measurement capabilities to verify the accuracy of the system’s analog inputs and outputs. This ensures that the control system is receiving and transmitting correct data.
  • Calibration: The card is used to calibrate the analog input and output channels to ensure they are within specified tolerances. This is critical for the safe and efficient operation of the turbine.
