Multi-channel structural testing and large-scale monitoring via networking
A high speed data acquisition system (high speed DAQ) is used to capture fast transient signals that standard data loggers may miss. The HP-CD Series is built for dynamic signal testing in harsh environments, including shock/impact, vibration/acceleration, and transient temperature/heat-flux measurements, with high-speed synchronous sampling up to 20 MHz.
HP-CD supports 1 Hz to 20 MHz sampling rate (software configurable). All channels can run synchronous parallel sampling, enabling accurate time alignment for impact and transient tests.
Yes. For dynamic testing, HP-CD works as a high speed data logger with synchronized sampling, real-time display, and local storage options—ideal for capturing short-duration events like shock, blast, and rapid vibration changes.
Yes. HP-CD is designed for strong EMI environments where cable noise and interference can degrade measurement quality. It is commonly deployed in demanding field tests requiring stable acquisition under heavy electromagnetic disturbance.
One HP-CD unit supports 8–32 channels. Multiple units can be networked to build a large channel-count system (including thousand-channel deployments) based on project architecture.

Programmable constant current: 0.001–50 mA (1 μA step; accuracy 0.05% ±2 μA)
Fixed excitation: 24 VDC / 40 mA, ±15 VDC / 50 mA
This covers common sensor powering needs for dynamic testing.
HP-CD supports software trigger, internal trigger, and external trigger, with sync recognition including level, rising edge, and falling edge. This helps ensure reliable capture of sudden events such as shock and blast tests.
HP-CD supports 1–3 MHz signal bandwidth (depending on configuration), which is critical for measuring high-frequency dynamic content in transient and vibration signals.
HP-CD can be configured with built-in local SSD storage (e.g., 1 TB) for real-time caching and logging. Data can be accessed through supported display/monitor methods, and optional dual-protection storage with a control PC is available for high-value tests.
