Building a Test System for High-Speed Data Streaming Applications

High-speed data streaming applications typically require maximum accuracy and long sampling times, including such applications as spectral monitoring, signal intelligence, LIDAR testing, optical fiber testing, radar and satellite signal acquisition, and software defined radio systems. These present unique engineering challenges requiring high throughput, and identifying design flaws and problems can contribute to reduced development costs and time to market, avoiding field recalls and costly system redesigns. The white paper discusses techniques for optimizing configuration of systems supporting high-bandwidth applications, by: Enabling high-speed real-time data streaming Designing applications optimizing system streaming performance Furnishing benchmarks that can be achieved in stream-to-disk and stream-to-memory applications

Analog Signal Conditioning for Accurate Measurements

By Jon Titus Q: Should I put some sort of circuit between my sensor and an analog-to-digital converter? A:Yes. You probably need some signal conditioning. The explanation below goes on for a bit, but stay with it and you'll understand what you need and why you need it. Before you make any connections, get the electrical specifications for the analog-to-digital converter (ADC) and for the sensor or sensors in your system. Let's assume the data-acquisition module uses a Maxim Integrated Products MAX197 12-bit ADC. This device can accept eight differential (2-wire) inputs or 16 single-ended (1-wire) inputs. Maxim's specifications show an input impedance of 21 kohms for single-ended inputs and 16 kohms for differential inputs.
