The R&S®ZVB series of vector network analyzers covers the frequency ranges from 300 kHz to 4/8 GHz and from 10 MHz to 14/20 GHz. 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
    ◇ 60001 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
