Country of Origin
This module was originally designed and manufactured in the United States by Greenspring Computers, a pioneer in the Industry Pack mezzanine standard.
Application Fields
The 320-1026C is utilized in rugged, high-reliability computing environments:
- Aerospace & Defense: Sensor data collection in flight simulators and telemetry systems.
- Industrial Research: High-precision laboratory automation and test stands.
- Medical Imaging: Analog signal digitization for diagnostic equipment.
- Energy Sector: Monitoring grid voltages and mechanical vibration in power plants.
Product Usage Instructions
- Carrier Integration: Plug the 320-1026C into a compatible IP carrier board (VME, PCI, cPCI, or PC/104). Ensure the 50-pin I/O connector is properly seated.
- I/O Termination: Connect the analog inputs via the carrier’s transition module or specialized IP cables. Use shielded twisted-pair cables for differential modes to maximize noise rejection.
- Address Mapping: Configure the base address in the carrier board’s logic so the host CPU can access the IP module’s register map.
- Software Initialization: Program the ADC control register to select the desired input range, channel mode (single-ended vs. differential), and trigger source (internal timer or external trigger).
- Data Retrieval: Monitor the “Data Ready” flag or use interrupts to read the digitized 16-bit values from the output FIFO.
Product Technical Description
The 320-1026C “IP-Precision ADC” focuses on signal integrity. Technically, it utilizes a high-quality successive approximation (SAR) ADC architecture combined with precision input amplifiers. The “C” revision often indicates industrial temperature grade components or specific hardware optimizations for lower noise floors. The module features an auto-scanning mode, allowing it to cycle through multiple channels automatically, which reduces the overhead on the system processor during multi-point data acquisition tasks.
Q&A (Common Questions)
Q: Can this module be used in a standard PC? A: Yes, but only if installed on a PCI or PCIe to Industry Pack (IP) carrier board.
Q: What is the benefit of the “16-bit” resolution? A: 16-bit resolution provides 65,536 discrete levels, allowing the system to detect much smaller voltage changes compared to standard 12-bit (4,096 levels) converters.
Q: Does it support simultaneous sampling on all channels? A: Most 320-1026 series modules use a multiplexed architecture, meaning channels are sampled sequentially. For true simultaneous sampling, a different IP module with dedicated ADCs per channel would be required.
Q: How do I handle calibration? A: The module typically includes software-accessible calibration constants stored in the ID PROM or uses on-board precision references to ensure long-term accuracy.
