Rohde & Schwarz's R&S ZVA50 network analyzer delivers four-port operation and can be used to test scenarios operating as high as 50GHz. It also delivers unique features and specifications for pulsed measurements useful in applications such as in radar and satellite signal analysis.

The analyzer's two integrated sources make it possible for the first time to perform measurements on multiport and balanced components at up to 50GHz with a single instrument.

The four-port architecture allows users to perform tests on balanced components such as those used for wired signal transmission at high data rates. The integrated coherent sources make it possible to measure linear and nonlinear DUTs using differential stimulus signals. The phase offset between the two signals can be selected by the user, thus allowing active components to be analyzed under real conditions.

The second integrated source of the R&S ZVA50 saves money by eliminating the external generator usually required for intermodulation and mixer measurements. This significantly simplifies operation and test setup.

Moreover, the integrated source sweeps the frequency range to be analyzed 10 times faster than external solutions, which substantially increases measurement throughput. S-parameter and intermodulation measurements can be performed simultaneously

The R&S ZVA50 supports all conventional methods required for pulsed measurements in radar and satellite applications. A large measurement bandwidth of 15MHz combined with high sampling rates allows pulse profile measurements with a time resolution of 12.5ns. Optimum values for dynamic range (130dB), output power (+13dBm) and measurement speed (3.5 ?s/point) also make the R&S ZVA50 a safe investment for future applications.

The R&S ZVA50 has a set of that provide support that guide users step-by-step through the settings for mixer measurements, pulsed and differential measurements, or calibrations to name just three examples.

Up to 60,000 measurement points per trace are possible, and convenient marker and analysis functions are provided for evaluating them. A total of 100 traces can be displayed.

Other highlights of the R&S ZVA50 include versatile mathematical functions, embedding/de-embedding using virtual networks for impedance matching, as well as comprehensive calibration methods.

The R&S ZVA50 is now available. The two-port model has a starting price of $122,800 in North America, and the 4-port model starts at $177,600.
