NI PCI-4451 2-channel dynamic signal acquisition card

NI PCI-4451 2-channel dynamic signal acquisition card

Performance parameters
Number of channels: 2 channels.
Resolution: 16 bits.
Sampling rate: 5kS/s to 204.8kS/s.
Dynamic range: 90dB, capable of achieving high-precision measurement and minimizing the impact of distortion and noise.
Frequency range: Within the frequency range from DC to 95kHz, it features an excellent amplitude flatness of ±0.1dB. At 1kHz, the total harmonic distortion (THD) is up to -90 dB, and at higher frequencies, it is down to -80 dB.
Input and output: 2 analog inputs and 2 analog outputs, all using oversampling ∑-Δ modulation converters; It also provides 8 5V TTL/CMOS digital lines.
Dimensions: 4.19 inches ×12.28 inches ×0.73 inches.
Interface: 68-pin VHDCI female connector.

Functional characteristics
Synchronization function: The acquisition channel can be synchronized with other devices in the user’s computer via the RTSI bus.
Triggering function: Supports both analog and digital triggering, which can flexibly meet the triggering requirements of different applications.
Protection function: It is equipped with short-circuit protection and ±42.4V overvoltage protection (regardless of whether it is powered or not).
High-precision acquisition: Due to the adoption of advanced ∑-Δ modulation converter technology, this acquisition card features high precision, low distortion and low noise. It can accurately collect and restore input signals and is suitable for applications with high requirements for signal quality.
