The toolbox also incorporates straightforward certain cases for. NI PXI-4472B 102. The test data are acquired at the following test conditions: Main Shaft SpeedPXI-4472B 보드 (Boa rd) 를 사용하였으며, 이 보드는 24bit 해상 유 체 충 격 압 력 측 정 용 압 전 센 서 특 징 19 Fig. These specifications are typical at 25 °C unless otherwise stated. . 하드웨어: Modular Instruments>>Dynamic Signal Acquisition and Analysis (DSA)>>PXI-4472B 문제점: NI 4472 와 NI 4472B DSA 보드의 차이점이 무엇입니까? 솔루션: AC 커플링 모드에서 측정을 할때, DSA 보드는 하이패스 RC(high-pass resistor-capacitor) 필터를 DC 성분을 제거하기 위해서 양과 음의. 1Hz. Everything works fine that way (as long as Calibration is disabled) regardless of whether I have anytype of sensor actually connected to my NI PXI 4472B DAQ or NI PXI 4330 card. Categories: NI. The system must be allowed to warm up for 15 minutes to achieve the rated accuracy. ¬±10 V input range or ¬±31 V with SMB-120 cable, Ability to synchronize up to. 102. 4 kS/s, Software-configurable AC/DC coupling and IEPE conditioning,. 4 kS/s, 0. 6 kS/s, the anti-aliasing filters of DSA device AI channels may not completely reject all out-of-band signals. 5 Hz AC/DC-Coupled, 8-Input PXI Sound and Vibration ModuleFor example, if I acquirethe same signal with a PXI-6221 and a DSA device such as the PXI-4461 at the same sample rate using a shared start trigger, the waveform acquired by the PXI-4461 will lag several samples behind the waveform acquired by the PXI-6221. NI PCI-4472B 8-channel 24-bit Vibration Optimized DSA. 1. 05-02-2007 09:47 AM. 2 kS/s, 102. You can synchronize multiple PXI‑4472B modules with each other for high‑channel‑count applications, or with other devices using the RTSI bus. 5 Hz. .

NI PXI-447x Specifications White Paper: Dynamic Signal Acquisition (DSA) Measurements Tutorial KnowledgeBase 31LFSSWD: What is the Difference Between Analog and Digital Triggered Acquisition for the NI 447x Boards? KnowledgeBase 3EE7N2NQ: Synchronizing Legacy Dynamic Signal Acquisition (DSA) Products with NI-DAQmxPCI-4472B National Instruments Sound and Vibration Device Apex Waves. This document lists specifi cations for the NI 447x Dynamic Signal Acquisition (DSA) devi ces including the NI PXI/PCI-4472 (NI 4472), NI PCI-4474, and NI PXI/PCI-4472B (NI 4472B). Det ails on the board are listed in Table 4. DAQ GETTING STARTED GUIDE PXI/PXI Express This document provides basic installation instructions for National Instruments PXI and. CAT-System). DAQmxチャンネルを作成VIで加速度計タスクと音圧タスクには、直接入力端子があり、励起を設定することができます。. I'm streaming data to disk at 80 to 100 kHz (all channels). How do I synchronize my NI 4472, 4472B, or 4474 PCI or PXI Dynamic Signal Acquisition (DSA) device with other DSA devices or other data acquisition devices using NI-DAQmx? Can I synchronize multipleNI 447x cards with different sample rates?. NI 447x Channel, Speed, and Resolution Specifications Applications Noise and vibration diagnostics Audio test and measurement National Instruments PXI-4472B 8-Channel 24-Bit Vibration-Optimized Dynamic Signal Acquisition Module National Instruments PXI-4472 24-Bit Vibration-Optimized Dynamic Signal Acquisition Module National Instruments PCI-6110 / PCI-6110E 4-Channel, 12-Bit, 5 MS/s/ch, Simultaneous-Sampling Multifunction DAQ For example, when we acquire at 1 kS/s with the PXI-4462, the first oversampled Fs is 128 kS/s, which is below the analog filter's cutoff frequency. With the PXIe-ready devices, the PXI Star Trigger pin does not exist. In LabVIEW, it would be a matter of either using a loop to get a set of data (say 1 seconds worth -- set up with the DAQmx functions), counting the.
