The R&S®NRP2 power meter offers a remote emulation feature that makes it possible to control the instrument by commands other than the built-in native SCPI commands. This feature allows the user to replace power meters, e.g. from other manufacturers, with the R&S®NRP2 power meter without having to change the remote control code. This application note describes how to use the remote emulation feature in general. Furthermore, it describes in detail the remote emulation for each supported instrument, limitations of the individual emulations and the remaining differences between the emulated and the original commands.

Modern societies worldwide depend on the performance, reliability and security of critical infrastructures and networks. There is a plethora of “new verticals” such as manufacturing, warehouse, mining, ports or other critical infrastructure, just to name a few. These “new vertical” use cases all have one common requirement: the mobile network needs to provide a superior performance compared to a commercial mobile network. In such environments 5G brings new capabilities to build fast and secure campus or private networks tuned to higher performance, which can increase productivity and efficiency. To be successful in these business-critical use cases, the wireless networks need to be as reliable as the wired ones. This educational note describes the different test methods to be able to verify the superior network performance and to help finding root causes of potential problems limiting the performance. We distinguish between passive tests and active tests.

Battery life time is usually one of the most important specifications for battery-powered devices. Depending on the application, life time requirements can range from tens of hours for typical wearables like smart watches to ten years for smart sensors. Understanding where and when energy is used in order to minimize power consumption is therefore key for any of these devices.The power consumption analysis tool was developed to make it easier for customers to analyze power consumption data collected with either the NGL, NGM or NGU power supplies from Rohde & Schwarz. It allows to easily capture power consumption data and analyze using basic measurements.

GSM standard 11.10 prescribes a number of tests requiring measurements on mobile stations under multichannel conditions (fading). The combination of Radiocommunication Tester CRTP02 or CRTC02 and Signal Generator SMIQ allows cost-effective performance of the most important fading tests, in particular the tests according to sections 13.2, 14.2 and 14.3 of GSM 11.10. The aim of this application note is to familiarize the user with all the capabilities offered by the above combination of measuring instruments. The user should then be able to quickly generate and run his own fading tests using the IEC/IEEE-bus control commands described in this application note. To facilitate reading of the following, the testers CRTP02 and CRTC02 are referred to as CRTx.

Vector Network Analyzers of the ZVR family measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. Using an inverse Fourier transform, the results can be transformed to the time domain. The impulse or step response of the DUT is obtained, which gives an especially clear representation of its characteristics. For instance, faults in cables can be directly localized. Moreover, special time domain filters, so-called gates, can be used to suppress unwanted signal components such as multireflections.

Performing precompliance measurements on power supplies requires using a line impedance stabilization network (LISN) for results that can be compared to limit values. While LISNs are standard in any precompliance lab, often no LISN is available for early R&D testing. If high accuracy is not your goal and you just need a simple tool for debugging, you can build your own LISN. Rohde & Schwarz oscilloscopes with powerful FFT analysis, are ideal for optimizing EMI filters or debugging unwanted emissions during development.

Reflection measurements are a common way of assessing antenna system performance. When a minimum amount of the transmitted signal is reflected, it indicates that the transmission energy can reach the intended coverage. Undesired high reflection causes the system to be inefficient and can damage components. Reflection measurements can be expressed in terms of return loss, VSWR and reflection coefficient.

The power efficiency of the drive electronics is a key parameter when developing electric drive systems. The conduction loss of the electric drive electronics is of special interest. One important parameter for determining the conduction loss is the RDS(on) of the MOSFET. When a switching MOSFET is off, it has a high drain-to-source voltage, but when it is turned on, the voltage drops to just a few hundred millivolts. A highresolution oscilloscope is needed to measure these low voltages. Probe compensation and correct probing are also vital for accurate RDS(on) measurements.
