The instruments on display at Rohde & Schwarz's booth ( will include the company's recently announced network analyzer with a four-port architecture up to 50 GHz. With two integrated sources, the R&S ZVA50 makes it possible to perform measurements on multiport and balanced components in this frequency range using a single instrument. The four-port architecture allows users to perform tests on balanced components, which are increasingly used for wired signal transmission at high data rates. The integrated coherent sources make it possible to measure linear and nonlinear devices under test (DUTs) using differential stimulus signals. The phase offset between the two signals can be selected by the user, thereby allowing active components to be analyzed under real conditions.

In addition, the second integrated source of the R&S ZVA50 eliminates the external generator that is usually required for intermodulation and mixer measurements. The R&S ZVA50 supports all conventional methods required for pulsed measurements in radar and satellite applications. A measurement bandwidth of 15 MHz combined with high sampling rates allows pulse profile measurements with a resolution of 12.5 ns. Other features include optimum values for dynamic range (130 dB), output power (+13 dBm), and measurement speed (3.5 s/point).

Agilent Technologies ( will offer a sampling of its extensive product lines including nonlinearvector- network-analyzer (NVNA) capability for its PNA-X microwave network analyzer from 10 MHz to 26.5 GHz. The Agilent NVNA software effectively converts a four-port PNA-X into a highperformance, nonlinear analyzer. The capability employs nonlinear scattering parameters called X-parameters and nonlinear pulse envelope domain capabilities. These features make it ideal for design and research work on active RF components. Data can be displayed in time, frequency, power, or user-defined custom domains, providing additional insight into the nonlinear behavior of components. The PNA-X microwave network analyzer is also available for traditional linear vector network analysis.

In addition, Agilent will offer demonstrations of new analysis capabilities for its PSA high-performance spectrum analyzer and mid-range model N9020A MXA signal analyzer. For example, analysis bandwidth for the 44- and 50-GHz PSA models will be extended to 80 MHz using a 14-b, 80-MHz-bandwidth digitizer. By using the PSA's builtin flexible digital modulation analysis or connecting to Agilent's 89600 series vector-signal-analysis (VSA) software, engineers should be able to easily analyze and troubleshoot a wider variety of complex digital-modulation formats. The added two-channel analog baseband analysis for the N9020A MXA signal analyzer will allow operators to use a single instrument for both baseband and RF analysis to 26.5 GHz.
