  • Spectral Analysis with a Vector Network Analyzer
    Vector network analyzers (VNAs) are widely used in research, manufacturing, and service environments. These instruments contain stimulus signal sources and receivers with one or more frequency converters. Copper Mountain Technologies produces several VNA models including the Planar 304/1 VNA
  • Measurement of Electronic Component Impedance Using a Vector Network Analyzer
    impedance. Such methods are based on the use of bridges (with or without auto-balancing), resonators, precision current and voltage meters, and network analyzers. The vector network analyzer (VNA) has recently become a powerful tool for analyzing impedance in a broad band, which partially covers the GHz
  • Mini Case Study: R60 1-Port VNA in Antenna Design Examination for Ministry of Economic Affairs in Taiwan
    CMT's 1-Port Vector Network Analyzers have been recognized as a reliable VNA for evaluation of antennas designed and built by students and engineers. The R60 was recently accepted for Antenna Design Examination conducted by the Industrial Development Bureau, Ministry of Economic Affairs, in Taiwan.
  • Time Domain with a CMT VNA
    A Vector Network Analyzer (VNA) natively measures complex S-parameters of a device under test (DUT) in the frequency domain mode by sweeping across various frequency points. While there is an exhaustive list of measurements that can be accomplished in the standard frequency domain mode - using
  • Measurement of Radar Cross Section Using the VNA Master Handheld VNA Application Note
    by the target. This application note describes how a. modern battery-powered / portable Microwave Vector Network Analyzer with Time Domain Gating can make it. easy to do RCS tests on the flight line or in the field.
  • Optimizing VNA Measurement Speed
    Users of Vector Network Analyzers (VNAs) often need to estimate and strive to optimize their instrument†TMs measurement speed. Many RF Engineers are interested in the tradeoffs between speed, accuracy and resolution in VNA measurements, especially those striving to achieve optimal automation
  • Voltage and Current Measurements with a VNA and DMM
    Vector Network Analyzers (VNAs) are used to measure the reflection and transmission coefficients, or S-parameters, of a Device Under Test (DUT). When the DUT is passive, the VNA may be the only tool necessary. But some devices are active and require an external power source for operation
  • Measurements in 75 Ohm Coaxial Transmission Lines Using a 50 Ohm VNA
    One application of a vector network analyzer (VNA) is the measurement of 75 ? coaxial transmission lines. In this article, we will discuss making these measurements using the most common type of VNAs, which have 50 ? test ports, in conjunction with 50?-to-75? Minimum Loss Pads (MLP), i.e.
