Analog I/O devices process analog signals (e.g., output of transducers) and output the results in analog format.
|
|
Analog-to-digital converter (ADC) chips transform information from analog to digital form.
|
|
Bit error rate testers are devices or procedures that measure the bit error rate (BER) for a specific transmission.
|
|
Data acquisition is the digitizing and processing of multiple sensor or signal inputs for the purpose of monitoring, analyzing and/or controlling systems and processes. Signal conditioning includes the amplification, filtering, converting, and other processes required to make sensor output suitable for rereading by computer boards.
|
|
Data acquisition I/O modules or cards have both input and output functionality. Digital or discrete I/O modules include on-off signals used in communication, user interface, or control.
|
|
Digital I/O devices process digital signals (e.g., outputs from a controller) and output the results in digital format.
|
|
Digital signal processors (DSPs) are specialized microprocessors designed specifically for digital signal processing, usually in real-time. DSPs can also be used to perform general-purpose computations, but are not optimized for this function.
|
|
Digital-to-analog converters (DAC) transform a digital number into a corresponding analog voltage or current.
|
|
I/O Modules, I/O cards and I/O boards are used to accept data (input) from computers, sensors, transducers, PLCs, etc., and then distribute the data (output) to other devices in the system.
|
|
Matrix switching systems rout signals (RF, video, audio, data, and others) from multiple inputs to multiple outputs.
|
|
Network test equipment is used to test, probe, and analyze telecommunication, network and telephone systems.
|
|
Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.

|
PCI products are devices that use the peripheral component interconnect (PCI) bus standard. PCI products include bridges, extenders, and power supplies. They also include bus interface, adapter, memory, mass storage, networking, and serial communications modules.
|
|
Signal converters contain inputs for one type of signal and outputs of another. Features can also include filtering and amplification or attenuation.
|
|
Spectrum analyzers and signal analyzers display raw, unprocessed signal information such as voltage, power, period, wave shape, sidebands, and frequency. They can provide the user with a clear and precise window into the frequency spectrum.
|
|
Video processor boards are used to process video, medical imaging, automated optical inspection, and other related activities. They can be fitted with between one and a thousand digital signal processing (DSP) units in order to increase the computing power of the board.
