Product Performance
Event counting capability up to 4 gigabit events; frequency measurement range 1.16×10⁻³Hz to 2.5MHz; period/pulse width measurement range 400ns to 8.5899×10⁶s; orthogonal position measurement supports sin/cos signals up to 1MHz, with 32-bit counter and limit/modulus check functions.
Square wave/pulse sequence generation range 0.0076Hz to 2.5MHz, output signal accuracy ±0.1%, inter-channel synchronization error ≤10ns. VMEbus interface data transfer rate up to 29.5MB/s, supporting redundant transmission mode (14.8MB/s). DMA data transfer reduces host response time, meeting real-time control requirements.
Built-in self-test function covers power supply, processor, memory, and channel circuits, with diagnostic coverage ≥99%, and fault information uploaded in real time via VMEbus. It maintains stable operation in the wide temperature range of -40°C to 85°C, with Mean Time Between Failures (MTBF) ≥800,000 hours (MIL-HDBK-217F, 25℃ environment).
