Manufacturers : RF and microwave electronics : RF network analyzers

Network analyzers are used to determine the radio frequency (RF) characteristics of various electrical systems and are widely used in radio frequency (RF) and microwave applications for the measurement of a circuit's unknown scattering parameters (s-parameters). Network analyzer systems enable complete characterization of a network through measurement of the magnitude and phase of its input and transfer characteristics. A vector network analyzer (VNA) measures a performance of a radio frequency (RF) and/or microwave/millimeter wave device under test (DUT) and produces measured results in terms of network scattering parameters. Vector network analyzers transmit a microwave signal to a test device and receive a return signal to enable characterization of the test device. VNAs enable a user to easily identify a fault in a cell site component and to measure the distance from the test device to a fault or discontinuity. A VNA also enables calibration to extend the test port connection to the end of a cable connected to the test port by accounting for any phase and amplitude differences. Radio frequency network analyzer systems consist of a network analyzer and may include a multi-port test set. Typically, these systems include a display device to present a graphical vector representation of the network characteristics. The network analyzer integrates a radio frequency source with built-in couplers for signal separation, a narrow band receiver, a display and a processor.
