NI SCXI-1162 high-performance data acquisition module

NI SCXI-1162 high-performance data acquisition module

Channel characteristics
Number of channels: It usually has 8 analog input channels, which can simultaneously collect data from multiple signal sources. It is suitable for application scenarios that require the simultaneous monitoring of multiple physical quantities.
Channel type: Supports single-ended and differential input modes. Differential input can effectively suppress common-mode noise, improve the accuracy and anti-interference ability of signal acquisition, and is suitable for measuring small signals or conducting measurements in noisy environments.
Input characteristics
Input range: It features multiple configurable input voltage ranges, including ±10V, ±5V, ±2.5V, ±1V and ±0.5V, etc. The appropriate range can be flexibly selected based on the amplitude of the input signal to achieve the best measurement resolution and accuracy.
Input impedance: The input impedance is relatively high, generally greater than 10MΩ. This can reduce the load effect on the signal source under test and ensure that the collected signal can truly reflect the characteristics of the original signal.

Electrical performance
Resolution: It adopts A 16-bit A/D converter, which can precisely convert analog signals into digital signals, and can distinguish minute voltage changes within the full scale range, with a resolution of up to 1/65536.
Sampling rate: The maximum sampling rate can reach 200kS/s, enabling rapid collection of dynamically changing signals. It has excellent performance in collecting high-frequency signals or transient signals.
Accuracy: Throughout the entire working temperature range, the measurement accuracy can reach ±0.05% of the full scale, featuring high measurement accuracy and stability.
