Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function

Linear variable differential transformer (LVDT) and rotary variable differential transformer (RVDT) signal conditioners are devices that translate the linear or rotary movement of a ferromagnetic armature into an AC voltage that is proportional to the armature position

Temperature signal conditioners accept outputs from temperature measurement devices such as resistance temperature detectors (RTDs), thermocouples, and thermistors. They then filter, amplify, and/or convert these outputs to digital signals, or to levels suitable for digitization

Signal amplifiers accept signals from sensors and other devices and amplify them to levels suitable for further processing or digitization by computer elements

Signal converters contain inputs for one type of signal and outputs of another. Features can also include filtering and amplification or attenuation

Magnetic receivers use the electromagnetic principle to receive and analyze signals. The simplest of these devices is the telephone

Radio modems are radio frequency transceivers for serial data. They connect to serial ports (RS232, RS422, etc.) and transmit to and receive signals from another matching radio modem

Analog-to-digital converter (ADC) chips transform information from analog to digital form.

Sensor transmitters are measurement or signal conditioning packages that provide a standard, calibrated output from a sensor or transducer in the form of a current loop output (e.g., 4-20 mA

Current loop converters convert an analog or digital signal to a current loop output such as 4-20 mA or 0-20 mA

RF waveguide amplifiers accept a varying input signal and produce an output signal that varies in the same way, but with a larger amplitude

Data acquisition input modules accept sensor and other signal output for data acquisition systems. They may include signal conditioning prior to the analog-to-digital conversion stage

Frequency-to-voltage converters accept a signal and convert its frequency to a corresponding analog voltage level

Bridge conditioners are instruments that provide excitation and support for strain gages, Wheatstone bridges, load cells, and sensors. They also include circuitry for signal conditioning, amplification, and processing

Codec chips are used to encode and decode (or compress and decompress) various types of data, particularly when the bulk storage is required.
