NI PCI-4452 4-channel, 16-bit dynamic signal acquisition card

NI PCI-4452 4-channel, 16-bit dynamic signal acquisition card

Performance parameters
Number of channels: 4 channels.
Resolution: 16 bits.
Sampling rate: 5kS/s to 204.8kS/s.
Dimensions: 4.19 inches ×12.28 inches ×0.73 inches.
Analog I/O connector: 68-pin VHDCI female connector.

Functional characteristics
Input configuration: A balanced differential input with simultaneous sampling is adopted, which can be configured as a single-ended reference channel through the BNC-2140 DSA attachment. It can connect single-ended or differential signals, whether they are floating signals or ground reference signals, and determine whether a capacitor is set in the signal path through a software-programmable switch.
Trigger mode: It has pre-trigger mode, delayed trigger mode and post-trigger mode.
Measurement function: The card comes with a Measure function, which can be used to directly obtain information from the DAQ board, GPIB instrument or serial port device, and directly set the data to the Excel worksheet cells, facilitating users to analyze and generate reports using Excel.

Application field
Acoustic research: It can be used to collect sound signals, such as in environmental noise monitoring, audio equipment testing, etc. It can accurately record the waveform and spectrum information of sound, providing data support for acoustic analysis.
Vibration analysis: In fields such as mechanical vibration testing and structural health monitoring, it is used to collect signals from vibration sensors, analyze the vibration characteristics of mechanical structures, and detect potential faults and damages.
Dynamic process monitoring: It is applicable to signal collection for various dynamic physical processes, such as automotive collision tests and explosion tests, and can capture instantaneous signal changes, providing key data for the research and analysis of these processes.
