PXI-5422 - NI Waveform Generator

Description

The NI PXI-5422 is equipped for performing self-calibration, which alters the gain and counterbalance of the fundamental and direct analog paths. Self-calibration only uses a locally available A/D converter (ADC) to quantify the output voltage. The user can execute self-calibration on the NI PXI-5422 by following strategies like verifying the DC Gain and Offset Accuracy and adjusting the Analog Output systems. Be that as it may, output impedance, oscillator recurrence, and the calibration ADC cannot be balanced amid self-calibration. This model comes in four presentations: the PXI-5422 with 8 MB memory (part number: 779087-01), 32 MB memory (part number: 779087-02), 256 MB memory (part number: 779087-03), and 512 MB memory (part number: 779087-04). The device has a maximum bandwidth of 80 MHz, with a maximum update rate of 200 MS/s. The instrument operates using the NI-FGEN driver software which is installed from the NI-FGEN DVD. The DVD also contains the FGEN Soft Front Panel which is essential to handling the signal generator. The software installation can begin automatically on insertion of the NI-FGEN DVD.However, in the event that the user is developing an application for the generator, an ADE such as LabVIEW or LabWindows/CVI is required. Also, configuration of the software can be carried out using the Measurement & Automation Explorer (MAX) tool. The NI PXI-5422 has 5 I/O connectors: the CH 0, CLK IN (SMB jack), PFI 0 (SMB jack), PFI 1 (SMB jack), DIGITAL DATA & CONTROL connectors (68-pin VHDCI female receptacle). This waveform generator acknowledges an outside PLL Reference Clock and can phase-lock the inside Sample Time-base Clock to the outer Reference Clock. The signal on this connector can also be utilized as a Sample Clock source.  This model acknowledges a trigger from an outside source and can begin or step through waveform generation or course signals from a few clock, event, and trigger sources. It routes the 16-bit digital patter outputs, computerized pattern clock output, trigger outputs, trigger sources of inputs, and a clock input.

Analog input module is a device used to collect and process analog signals, which is usually composed of analog input circuit, analog-to-digital converter (ADC), filter and interface circuit. The analog input circuit is responsible for converting the external analog signal into a voltage or current signal, and then converting the analog signal into a digital signal through an analog-to-digital converter, and finally filtering and enhancing the signal through a filter, and finally output to a computer or other control equipment for processing and analysis. Working principle 1. Analog input circuit: The analog input circuit is a key part of the analog input module, which is mainly responsible for converting the external analog signal into a voltage or current signal. Common analog input circuits include resistance divider circuit, current voltage circuit and so on. The resistance divider circuit realizes the signal conversion through the series parallel combination of resistors, and the current voltage circuit realizes the signal conversion through the product of current and resistance. 2. Analog-to-digital converter (ADC) : The analog-to-digital converter is the core component in the analog input module, which is responsible for converting analog signals to digital signals. The analog-to-digital converter discretizes the input voltage or current into a series of digital values according to its magnitude, and converts the continuous analog signal into a discrete digital signal through a process of sampling and quantization. Common analog-to-digital converters include successive approximation analog-to-digital converters and integral analog-to-digital converters. 3. Filter: The filter is an important part of the analog input module, which is mainly used to filter and enhance the signal. The filter can improve the quality and stability of the signal by removing high-frequency noise and interference signals, thus improving the accuracy and reliability of subsequent processing. 4. Interface circuit: The interface circuit is the connection bridge between the analog input module and the computer or other control equipment, which is responsible for converting the digital signal into a form that the computer or other control equipment can recognize and process. Interface circuit usually adopts serial communication interface or parallel communication interface, and realizes data exchange and communication with computer or other control equipment through data line and control line.
