Easy creation of customized multi-channel, multi functional, test and measurement systems
Electronic test and measurement, driven by necessity, continues to move in the direction of multi-channel and multi-functional instruments. Electronic devices under test continue to increase in complexity using parallel and array typologies that require more measurements to be made at higher speed while maintaining time coherence.

Mechanical Measurements Using Digitizers
Measurements on mechanical devices and systems using a modular digitizer requires the use of a variety of transducers or sensors in order to convert mechanical parameters such as force, acceleration, pressure, rotational speed, and their kindred into electrical signals you can measure. This article is a primer on making such measurements using a modular digitizer. […]
Power Measurements Using Modular Digitizers
Line power measurements are commonly required to evaluate the performance of devices or circuits. Modular digitizers can make these power measurements. Digitizers are voltage responding measurement instruments. They can also measure current using suitable current probes or current shunts. Acquiring current and voltage next leads to calculating power based on the product of the acquired […]
RF Measurements Using a Modular Digitizer
Modern modular digitizers, like the Spectrum M4i series PCIe digitizers, offer greater bandwidth and higher resolution at any given bandwidth than ever before. Although they are in the class of general purpose measuring instruments they are capable of many RF and lower microwave frequency measurements. This article focuses on some examples of common RF measurements […]
Signal Processing for Digitizers
Modular digitizers allow accurate, high resolution data acquisition that can be quickly transferred to a host computer. Signal processing functions, applied in the digitizer or in the host computer, permit the enhancement of the acquired data or the extraction of extremely useful information from a simple measurement. Modern digitizer support software, like Spectrum’s SBench 6 […]
Source-Response-Testing with AWGs and Digitizers combined in one instrument
In the world of electronic testing there are two classes of testing. Self-excited electronic devices such as power supplies, oscillators, transmitters, and signal generators are tested using data acquisition type instruments like digitizers, oscilloscope, or spectrum analyzers. The second class of testing involves testing devices like amplifiers, filters, receivers, and digital interfaces that must be […]
