National Instruments PXIe-4499 PXI Sound and Vibration Module
The PXIe-4499 (Part Number: 781370-01) Sound and Vibration Module has a digitizer or ADC that can test signals that contain frequency parts over the Limit Nyquist. The Nyquist data transfer capacity is aliasing. The greatest danger of aliasing is that the user cannot determine if the aliasing happened while watching the ADC output. If an input signal contains a few frequency components or sounds, a portion of these parts could be represented accurately, while others contain alias artifacts. Lowpass filtering is used to eliminate components over the Nyquist frequency either previously or amid the digitization procedure can ensure that the digitized informational collection is free of aliased components. DSA gadgets utilize both digital and analog lowpass channels to accomplish this protection.
The delta-sigma ADCs on the NI PXIe-4499 incorporates oversampled engineering and sharp digital channels with cut-off frequencies that track the inspecting rate. In this manner, the filter consequently changes to follow the Nyquist frequency, even though the computerized channel eliminates almost all. The NI PXIe-4499 supports the AI.RemoveFilterDelay property. Whenever empowered, the gained information is naturally adjusted so the first acquired sample is in line with the digital trigger. The trigger circuit creates an inside digital trigger, despite the input signal and the characterized trigger levels. For instance, the user can arrange the gadget to begin gaining tests after the input signal crosses a certain limit. The user can also course this inside trigger to the PXIe-4499 trigger bus to synchronize the beginning of the acquisition task by one gadget with the operation of different gadgets in the framework.
The PXIe-4499 has a "Last Time Buy" date of March 28, 2024 from NI- but it will remain available for purchase and repair with Apex Waves.
