Product Performance

The 16-channel synchronous sampling error is ≤10ns, which can accurately capture the phase relationship of multi-channel signals, adapting to scenarios requiring synchronization such as vibration analysis and power monitoring. The combination of 1MSPS sampling rate per channel and 16-bit no-missing-code resolution achieves a conversion accuracy of ±0.01% full scale and a temperature drift of ≤5ppm/℃, maintaining measurement stability over a wide temperature range.

The signal conditioning circuit integrates anti-aliasing filtering (cutoff frequency 400kHz, attenuation ≥80dB) and common-mode rejection (≥100dB), which can effectively filter out high-frequency interference and common-mode noise in industrial environments. The optical isolation design avoids ground loop interference, and the 2.5kV AC isolation voltage ensures the module operates safely in high-voltage scenarios.

The data interaction rate with the VMEbus master controller is ≥100MB/s, supporting DMA direct memory access to reduce CPU occupancy; a built-in 4MB data buffer can temporarily store sampled data to avoid data loss. The module has a Mean Time Between Failures (MTBF) ≥1,000,000 hours (MIL-HDBK-217F, 25℃ environment), adapting to 24/7 continuous production scenarios.
