Description
GE VMIVME3125
- Technical Specifications (representative VMIC 3100 family):
- Channels: Up to 32 single-ended or 16 differential inputs
- Resolution: 16-bit or higher (verify with datasheet)
- Input ranges: ±10 V, ±5 V, 0–10 V, 0–5 V, 4–20 mA; software-selectable gains
- Sampling: Up to 200 ksamples/s aggregate; simultaneous sampling optional on variants
- Features: Autocalibration, input filtering, overrange detection
- VME interface: A32/D32 master/slave with DMA
- Functional Features:
- Excellent accuracy and low noise for precision data acquisition

- Autocalibration reduces maintenance
- Application Scenarios:
- High-precision test and measurement
- Vibration analysis and acoustic measurement
- Laboratory automation and scientific instrumentation
- Performance Parameters:
- High effective number of bits (ENOB) and low THD for dynamic measurements
- Low crosstalk and offset drift
- Material and Structural Characteristics:
- 6U VME board with shielded front-panel connectors; high-quality analog front-end components
- Working Principle: Uses precision ADCs and programmable gain instrumentation amplifiers (PGIAs) to digitize input signals; samples are stored in FIFO and transferred to VME memory via DMA.
- Installation Requirements:
- Install in 6U VME chassis with proper cooling
- Use twisted-pair or shielded cables for analog inputs; keep away from high-power lines
- Usage Notes:
- Perform periodic calibration for best accuracy
- Configure input ranges to maximize signal dynamic range and avoid clipping
