National Instruments PCI-4451 Dynamic Signal Acquisition Device
The National Instruments PCI-4451 (Part number: 777534-01) Device comes with a total scope of usefulness for sound and vibration checking and investigation applications. This instrument has two sources of input and two outputs. The four-input PCI-4451 is perfect for applications that include a high input channel. The acquisition channels of the PCI-4451 device offer the possibility to be synchronized with different gadgets in the user’s PC by utilizing an RTSI bus. Both simple and digital activating are accessible on this device.
This model comes with 90 dB of dynamic scope that makes high-precision estimations feasible and aggregates to distortion and low noise impacts. In this model, there is ±0.1 dB of superb amplitude flatness inside the frequency range of DC to 95 kHz, with the highest THD detail of - 90 dB at 1 kHz and the lowest THD of - 80 dB at higher frequencies. Both the simple input and the simple output hardware have oversampling delta-sigma adjusting converters. Delta-sigma converters are characteristically straight, work in block divider antialiasing/imaging channels, and have determinations that surpass other ordinary innovation for this application with respect to THD, SNR, and sufficiency evenness. The user can utilize these astounding determinations and highlights to secure or create signals with high precision and loyalty without presenting noise or out-of-band aliases.
The NI PCI-4451 device offers 2 inputs and 2 outputs, 16-bit, resolution, 5.0 to 204.8 kS/s sampling rates, overload location, AC/DC coupling, multiple-board synchronization, and 8 5V TTL/CMOS computerized lines.
PCI-4451 Obsolete Status has been announced by National Instruments, but will still be available for purchase and repairs by Apex Waves.
