Fukuda CardioMax FX-3010 ECG Machine Mainboard PCB-6380D-C1 Used in Good Working

►Brief Description

The Mainboard PCB-6380D-C1 is the core component of the FX-3010 ECG Machine. This mainboard receives microvolt-level bioelectrical signals from the patient's leads. It coordinates and manages all operations of the machine, including keyboard input, LCD display, thermal printhead drive, motor control, and external communication. It is responsible for analog-to-digital conversion, filtering, analysis, and temporary storage of signals, providing the final waveform data for printing and display. Any ECG signal acquisition-processing-output process must pass through the precise processing of this mainboard.

►Main Functions of the Motherboard

1. Preamplifier and Lead Selector

Function: This is the first stage of signal processing. It uses a multiplexer to switch different electrode combinations based on the user-selected lead mode (I, II, III, aVR, aVL, aVF, V1-V6). Subsequently, a high-input-impedance, low-noise instrumentation amplifier provides initial amplification of the weak millivolt-level ECG signal.

2. Analog Signal Conditioning Circuit

Function: Further processes the initially amplified signal. This mainly includes:

Filtering: Removing baseline drift (such as that caused by breathing or exercise) using a high-pass filter, and suppressing high-frequency noise such as EMG interference using a low-pass filter. Typically, a powerful power frequency notch filter is also included to specifically filter out 50/60Hz power supply interference.

Amplification: The main amplifier amplifies the signal to a level suitable for processing by the analog-to-digital converter (ADC).

3. Analog-to-Digital Converter

Function: Converting the conditioned, clean analog ECG signal into a digital signal for subsequent digital processing and analysis by the microprocessor. This is a crucial step in the transition of signals from the "physical world" to the "digital world."

4. Processor and Digital Signal Processor

Function: This is the "brain" of the motherboard. It is responsible for:

Executing digital filtering algorithms to further optimize the waveform.

Running ECG analysis programs to perform automatic measurements (such as heart rate and intervals) and arrhythmia analysis.
