HP-DAS is a high-accuracy, multi-channel dynamic signal DAQ and analysis system with 24-bit ADC, synchronous parallel sampling up to 256 kHz, and an integrated Windows platform (12th Gen i7 / 16GB RAM / 1TB SSD / 10″ capacitive touchscreen) for on-site acquisition, display, and storage.
| Universal mixed inputs (true multi-signal) | Each input channel can freely select analog measurement types (strain, voltage, current, etc.) without extra auxiliary modules. |
|---|---|
| High-speed synchronized acquisition | All channels sample/display/save synchronously, up to 256 kHz, with 1 Hz step software adjustment. |
| Online self-calibration for long-term stability | Automatically compensates for temperature/humidity effects, time drift, and temperature drift to improve long-term measurement stability. |
| Hardware auto-balance (zero) without losing range | Automatically adjusts bridge zero to keep full-scale symmetry; supports TEDS and intelligent cable functions. |
| Automatic fault diagnosis | Detects front-end sensor issues (short/open circuit, over-range/saturation, full-scale faults) and provides troubleshooting solutions. |
Built for demanding test environments and long-duration acquisitions, HP-DAS combines universal mixed inputs with long-term stability features like online self-calibration, automatic balancing, and fault diagnosis. The integrated Windows touchscreen design reduces setup time and supports safer data handling through local SSD storage and optional dual-storage protection.

Q1: What’s the difference between HP-DAS and Linux-based systems?
HP-DAS integrates a Windows platform with a 10-inch touchscreen, making on-site operation, display, and data management more convenient for many test workflows.
Q2: How does HP-DAS ensure long-term accuracy?
Online self-calibration helps compensate for environmental effects and drift, while hardware auto-balance maintains measurement symmetry.
Q3: How is data protected during long acquisitions?
A built-in 1TB SSD supports real-time backup, and an optional dual-storage strategy with the control PC improves data integrity.
