Digilent products are well-suited to support each of these stages.<\/p>\n
Data Acquisition<\/h3>\n
The first step in PdM is capturing high-fidelity data from industrial assets. This includes vibration, temperature, current, and other signals that may indicate wear or failure.<\/p>\n

- Analog Discovery Pro ADP3450<\/strong><\/a>
\nA professional-grade mixed-signal oscilloscope with 4 analog channels and 16 digital channels. It supports up to 0.5 GS\/s sampling and 14-bit resolution, making it ideal for capturing subtle changes in vibration or current signals. It also includes a waveform generator, logic analyzer, and more, all accessible via Digilent\u2019s free Waveforms software<\/a>.<\/strong><\/li>\n- Analog Discovery 3<\/a><\/strong>
\nA compact, USB-powered device offering similar core functionality for educational or portable setups. It\u2019s ideal for lab-based PdM experiments or classroom demonstrations.<\/li>\n<\/ul>\nThese tools can interface with sensors such as accelerometers (for vibration), thermocouples (for temperature), and current clamps. For example, a failing motor bearing may show a shift in its vibration frequency, which is something the ADP3450<\/a> can detect with precision.<\/p>\n
Processing and Analysis<\/h3>\n
Raw sensor data must be processed to extract meaningful insights. Real-time edge processing is often essential to reduce latency and handle large datasets efficiently.<\/p>\n

- Eclypse Z7<\/strong><\/a>
\nFeatures a Zynq-7000 SoC combining an ARM processor with an Artix-7 FPGA. This hybrid architecture supports high-speed data acquisition and real-time analysis, such as Fast Fourier Transforms (FFT) for vibration spectral analysis.<\/li>\n- Nexys A7<\/strong><\/a>
\nA versatile FPGA board ideal for implementing custom logic for anomaly detection, signal filtering, and other PdM algorithms.<\/li>\n- <\/a>Waveforms Software<\/a><\/strong>
\nEnables real-time visualization, scripting (Python, JavaScript), and automation. Engineers can set up threshold-based alerts or create custom analysis routines.<\/li>\n<\/ul>\nThis stage transforms raw data into actionable intelligence by detecting anomalies before they become failures.<\/p>\n
Connectivity and Visualization<\/h3>\n
Once analyzed, data must be communicated to a central system for monitoring and decision-making.<\/p>\n
Digilent devices support USB and Ethernet<\/strong> connectivity, allowing integration with cloud dashboards, SCADA systems, or enterprise platforms. Importantly, they can transmit processed data<\/strong>, reducing bandwidth usage and improving scalability.<\/p>\n
WaveForms also supports scripting and remote control, enabling integration with custom dashboards or alert systems.<\/p>\n
Example Workflow: Vibration-Based Predictive Maintenance<\/h4>\n
Here\u2019s a simplified PdM workflow using Digilent tools:<\/p>\n
- \n
- Sensor Integration<\/strong>: An accelerometer connects to the ADP3450\u2019s analog input.<\/li>\n
- Baseline Capture<\/strong>: The ADP3450 records the vibration profile of a healthy motor.<\/li>\n
- Real-Time Analysis<\/strong>: An FPGA (Eclypse Z7 or Nexys A7) performs FFT on incoming vibration data.<\/li>\n
- Anomaly Detection<\/strong>: The system compares live data to the baseline. Deviations trigger alerts.<\/li>\n
- Notification<\/strong>: The ARM processor on the Zynq-7000 SoC sends alerts via Ethernet to a dashboard or maintenance system.<\/li>\n<\/ol>\n
This setup allows maintenance teams to intervene before a failure occurs, which means saving you time, money, and resources.<\/p>\n
