Used ROHDE & SCHWARZ NRVD #9201615 for sale

ROHDE & SCHWARZ NRVD (Near-field Scanner - Vector Network Analyser) is a versatile electronic test equipment designed for measuring the characteristics of a wide variety of devices, components and systems. It features a vector network analyser (VNA) that can measure at both far-field and near-field distances; a vector signal analyser (VSA) for amplitude- and phase-sensitive signal analysing; a near-field scanner (NFSA) that can measure the radiation pattern of antennas; and a frequency-selective SWR (Standing Wave Ratio) meter for on-site measurements of resulting reflection coefficients of objects such as antennas. NRVD can be used to measure an almost infinite array of properties of a component, device, or system. It can be used to measure the scattering parameters (amplitude- and phase-dependent parameters) of a wide variety of components, such as amplifiers, directional couplers, filters, circulators, and multiplexers. It can also measure the frequency response of a system, including antenna systems. The vector network analyser also allows for measurement of the impedance and the VSWR (Voltage Standing Wave Ratio) of a device or system. In addition, the vector signal analyser can measure spectral parameters, such as channel power, broadcast and modem signals, and communication protocols. The VSA also allows for non-connected measurements such as voltage or current signals, as well as for impulse response or step response analyses. The near-field scanner is used to measure the radiation pattern of antennas or other objects, by scanning the object with a receiver antenna, recording the RSSI (Received Signal Strength Indicator) signal at multiple points. The field intensity is then calculated from the RSSI readings and data can even be collected for 3D plotting. Finally, the frequency-selective Standing Wave Ratio Meter can be used to measure the return loss of an antenna, cable or other passive device in-situ, which can be especially useful for on-site, field measurements. Overall, ROHDE & SCHWARZ NRVD is a versatile and powerful electronic test equipment that can be used to measure an extensive variety of properties for both active and passive circuitry and systems. It offers several types of analysis and can therefore be used in various types of applications, from RF design and engineering, to antenna and microwave engineering, to communications and broadcast engineering.
