To provide the increased bandwidth and data-transmission rates necessary for wireless data, voice, music, and video applications, engineers must contend with higher-order modulation schemes that place ...

National Instruments announces the NI PXI-4461, the industry's first 24-bit analog input/output data acquisition module for the PXI platform. With the release of this module, engineers now can ...

Dynamic signal analyzers (DSAs) have been a mainstay of test and measurement for almost 20 years. These versatile instruments, which analyze sub-100-kHz signals in both the time and frequency domain, ...

The physical features and components of a dynamic light scattering (DLS) instrument together with the technical specifications of the instrument are significant considerations when buying a new system ...

The dynamic range of an audio signal is the difference between the quietest discernible part of the signal and the loudest undistorted part of the signal. It is normally expressed in decibels (dB).

While selecting a DLS instrument, one must first know what needs to be measured. Researchers often know their specific application and samples quite well and they usually understand exactly what ...
