  • GPIB: Challenges and Potentials
    Adopted by a wide range of instrumentation applications, the General Purpose Interface Bus (GPIB) is now being challenged by emerging standards such as USB and LXI. This article examines the development potentials for GPIB and analyzes the future of this technology. A brief overview discusses
  • The Future for New Bus Technologies in Instrument Control and Connectivity
    For more than 20 years, scientists and engineers have widely used the IEEE 488 GPIB for automating instrumentation systems. As popular computer technology enters the test and measurement arena and buses such as USB, Ethernet, and IEEE 1394 are considered for instrument connectivity, questions arise
  • LAN Extensions for Instrumentation (LXI) Overview
    generation replacement for GPIB, such as the universal serial bus (USB), FireWire, CAN bus, PCI, and PXI, but none of these have met with wide industry acceptance.
  • Application: Modular Instrumentation Use Reed Relays
    There are many types of modular instrumentation platforms: VXI, PXI, PACs, Labview, AXie, USB, GPIB, etc. They all offer several different plug-in boards that carry out singular and/or multiple functions. Modular RF analog switching boards are now RF reed relays that allow passage of up to 17.5 GHz
  • An Introduction to Programmable Attenuator Systems
    or via a computer. Depending on the model, the maximum attenuation ranges from 0 dB to 127 dB, in steps as small as 0.1 dB. The attenuator is controlled by a combination of digital inputs, an analog voltage or via USB, RS-232, Ethernet or GPIB. These devices are bi-directional, so either port can act
  • Serial Communication Overview
    Serial is a device communication protocol that is standard on almost every PC. Do not confuse it with universal serial bus (USB). Most computers include two EIA-232 based serial ports. Serial is also a common communication protocol for instrumentation in many devices, and numerous GPIB
  • Application: Modular Instrumentation - Reed Relay
    Modular instrumentation has been around for the past 30 years, but continues to grow in popularity. The systems have become more functional with the ability to carry out multiple tasks in parallel. There are many types of modular platforms: VXI, PXI, PACs, Labview, AXie, USB, GPIB, etc, etc. All
