This Application Note describes how to configure and calibrate R&S ZVR network analyzers for conversion gain measurements of devices with two ports that have different impedances. Thus accurate measurements on frequency-converting devices such as low noise converters of sattellite receivers are possible.

The RSIB interface enables the network analyzers of the ZVR family to be controlled by means of Windows applications via DDE. The interface functions are contained in the DLL RSIB.DLL. The other DLL RSDDE.DLL provides functions for the DDE access to the instrument firmware. These functions are used by RSIB.DLL. The interface of these functions greatly corresponds to that of National Instruments for programming the GPIB. The function names are similar to those of the NI library but preceded by RSDLL. The two DLLs are part of the firmware and are updated with the firmware update kits.

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.

Spectrum and network analyzers are capable of measuring large amounts of data that require complex mathematical processing; MATLAB is a powerful tool for such operations. This application note describes how instruments can be controlled directly from MATLAB scripts and how measurement data can be imported into MATLAB. Only 32-bit MATLAB is supported.

5G networks will need to offer more capacity and flexibility while lowering the operational expenses of the system. Two new technologies can simultaneously address both the increase in capacity and the increase in energy efficiency: Virtualization & Massive MIMO. This white paper provides an overview of test solutions addressing current and future requirements for antenna verification including both conducted and over-the-air (OTA) test methods, which result from applying Massive MIMO antenna technology.This white papers complements the white paper (1MA276) from Rohde & Schwarz, which introduces fundamental theory behind beamforming antennas and provides calculation methods for radiation patterns, a number of simulation results as well as some real world measurement results for small linear arrays.
