ZVB4 4G的矢量网络分析仪ZVB4 品牌：罗德与施瓦茨Rohde&Schwarz The R&S®ZVB series of vector network analyzers covers the frequency ranges from 300 kHz to 4/8 GHz and from 10 MHz tGHz. 品牌：罗德与施瓦茨Rohde&Schwarz The R&S®ZVB series of vector network analyzers covers the frequency ranges from 300 kHz to 4/8 GHz and from 10 MHz tGHz. It has been designed for universal measurements on passive and active components. The R&S®ZVB series greatly simplifies vector network analysis especially for multiport measurements and measurements on balanced devices. Featuring comprehensive measurement functions, excellent specifications, high measurement and data transfer speeds and remote-control capability, the analyzers of the R&S®ZVB series are an ideal choice for both development and production applications. The compact versions of the 14 GHz and 20 GHz two-port models leave ample room for test setups in the lab, featuring a height of only 24 cm and a depth of 42 cm. New multiport concept Instruments with two or four test ports – for multiport and balanced measurements Two internal sources (four-port models) – to provide RF and LO signals for mixer measurements by means of a single unit Capability to perform balanced measurements – to characterize balanced DUTs by their mixed mode S-parameters Optional automatic calibration units – to speed up calibration and avoid operator errors Outstanding specifications points per trace Dynamic range better than 123 dB (typ. 130 dB) Power sweep range >50 dB High speed Measurement time < 4.5 ms for 201 test points (frequency sweep) Switching time between channels < 1 ms Switching time between instrument setups < 10 ms Data transfer time < 0.7 ms (201 test points via RSIB) Simultaneous measurement of more than one DUT Modern user interface Intuitive Windows-based operation via mouse Operation by means of hardkeys and softkeys Large number of channels, traces and setups that can be loaded simultaneously
