  • S-Parameters of a 50 to 75 Ohm impedance matching device using R&S®ZVx VNA

    This document describes how the advanced calibration techniques of the ZVA Vector Network Analyzers can solve the challenges of measuring the S-Parameters on impedance matching devices. The document describes the concept and setup required to perform the calibration of the ZVA and making the measurement. The procedure described in this application note applies to the ZVB and ZVT Vector Network Analyzers as well.

  • Transfer of Trace Data from R&S Network Analyzer ZVx to Microsoft Excel

    This application note describes how to directly transfer S-Parameter Trace Data from R&S Network Analyzers to Microsoft Excel using a direct connection like GPIB or LAN. Prerequisites are a PC running Microsoft Excel, a R&S Network analyzer like ZVA, ZVB or ZVT as well as a working remote control connection between PC and instrument like GPIB or LAN / Ethernet.

  • Using the Frequency Conversion Mode of the R&S®ZVR Vector Network Analyzer

    Using option ZVR-B4 (Frequency Converting Measurements), a ZVR Vector Network Analyzer can be used for measurements on frequency converting devices such as mixers and amplifiers. Using the ZVR's ARBITRARY mode, the source and receiver frequency ranges of the ZVR's generator and receiver, plus for two external signal generators, can be defined independently. As a result, mixer and intermodulation products such as conversion loss or sampling mixers, can all be measured. Used together with option ZVR-B6 (Reference Channel Ports), group delay measurements can also be made on frequency converting devices.

  • 4-Port Measurements with Vector Network Analyzer R&S®ZVR

    Three hardware modifications of the option External Measurements ZVR-B25 enable the bidirectional network analyzers of the ZVR-family to carry out 4-port measurements. For the measurements, the four ports PORT 1, PORT 2, INPUT b1 and INPUT b2 at the front panel of the ZVR(E) are utilized. The fifth connector, ie OUTPUT a1, is not required for this purpose. As detailed below, the necessary modifications of the test set of the analyzer are described for the model ZVR. Of course, the modifications can be done in a similar way for the model ZVRE as well.

  • Pulsed Measurements on GSM Amplifier SMD ICs with Vector Network Analyzer R&S®ZVR

    A special requirement for testing GSM components is to measure the electrical characteristics, such as the gain of a power amplifier, of the DUT under pulsed conditions. The test should be similar to real operating conditions for a mobile telephone.

  • Virtual Embedding Networks for R&S®ZVR and R&S®ZVC Network Analyzers

    Embedding and De-Embedding of virtual transformation networks for measuring scattering parameters with a ZVR or ZVC vector network analyzer.

  • Multiport Measurements using Vector Network Analyzer ZVR

    Using the optional three-port or four-port adapter (ZVR-B8 and ZVR-B14), PORT 1 and PORT 2 of the network analyzers of the ZVR family (ZVRL, ZVRE and ZVR) can be expanded to up to four ports. Thus automatic measurements on three- and four-port DUTs can be easily performed without any reconnection of ports being required. With the electronic switches in the adapters, switchover between the various ports is fast to the extent that the known high measurement and display speed of the analyzers of the ZVR family is fully maintained.

  • Measurements on Frequency-Converting DUTs using Vector Network Analyzer R&S®ZVR

    ZVR is a vector network analyzer equipped with selective input channels for determining phase relations. Thus a wide dynamic range can be obtained. For measurements on frequency-converting DUTs (output frequency not identical to input frequency), the generator and receiver frequency ranges can be separately set. For measurements on DUTs using a built-in conversion oscillator, as is the case here, the conversion frequency must be exactly known so that the receiver can be accurately tuned to the respective output frequency. The maximum receiving bandwidth is 26.5 kHz. When a wide dynamic range is required, this bandwidth has to be reduced with the consequence that the requirement for the DUT output frequency and the ZVR receive frequency to be in agreement will be greater.

  • Power Calibration of Vector Network Analyzer R&S®ZVR

    The option ZVR-B7 allows an enhanced power calibration of the source and of the receiver channels of a ZVR, then being active instead of the standard factory power calibration. Using an external power meter, the power level of input or output wave quantities will be adjusted to a desired value at an arbitrary reference plane.

  • Controlling External Generators and Power Meters with Network Analyzer ZVR

    With options ZVR-B4 (mixer measurements), ZVR-B5 (nonlinear measurements) and ZVR-B7 (power calibration) installed, signal generators and power meters can be controlled from ZVR network analyzers via the IEC/IEEE bus. Customary signal generators and power meters are supported by the device firmware. This application note describes how user-specific configuration files can be generated for and adjusted to external equipment of these two categories.
