Network Modems
(429 companies)
Network modems (modulators-demodulators) are devices or programs that allow computers to transmit data over telephone lines. They convert digital computer data to analog sound waves and then demodulate the carrier signals to decode the transmitted information.
RF Modules
(178 companies)
RF modules are partially finished circuits that can be incorporated into larger designs.
GPS Instruments and Devices
(323 companies)
Global positioning system (GPS) instruments and GPS devices are radio-navigational devices that provide accurate position information about objects on Earth, based on information from orbiting satellites.
Signal Amplifiers
(286 companies)
Signal amplifiers accept signals from sensors and other devices and amplify them to levels suitable for further processing or digitization by computer elements.
Chipsets
(39 companies)
Chipsets are single chips that provide many of the functions of a motherboard. Generally, they integrate the clock generator, bus controllers, system timer, interrupt controller, DMA controller, CMOS/RAM clock, and keyboard controller functions.
IC Modems
(42 companies)
IC modems enable computers to transmit data over telephone lines or via wireless signals.
GPS Chips and Modules
(69 companies)
GPS chips and modules compare signals from several geo-positioning satellites to determine position on the Earth's surface. GPS is an initialism for global positioning system.
Supervisory Control and Data Acquisition Systems (SCADA)
(321 companies)
Supervisory control and data acquisition (SCADA) systems are large-scale, industrial control and measurement systems that consist of a central host, one or more remote units, a communications network, and specialized software.
Auto Dialers
(15 companies)
Auto dialers are alarms that send signals when equipment malfunctions, a process variable exceeds a predefined limit, or another alarm-triggering event occurs.
RF Receivers
(272 companies)
RF receivers are electronic devices that enable a particular radio signal to be separated from all others being received and converted into a format for video, voice, or data.
SAW Filters
(88 companies)
SAW filters are electronic filters that are designed and manufactured using surface acoustic wave (SAW) technology. SAW uses piezoelectric transducers that, when excited, produce waves that are used to filter frequencies.
Signal Conditioners
(941 companies)
Signal conditioners provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
Standards and Technical Documents
(314 companies)
Standards and technical documents includes standards, codes, regulation, handbooks, manuals, comprehensive guides and other formal publications. Standards, codes, and regulation establish uniform specifications, procedures or technical criteria.
Relay Boards
(71 companies)
Relay boards are computer boards with an array of relays and switches. They have input and output terminals and are designed to control the voltage supply.
Energy Meters and Optical Power Meters
(121 companies)
Energy meters measure the total energy of a single pulse and optical power meters measure the average power of a continuous light beam.
