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.

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.

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.

Many serial interfaces use Manchester or non-return-to-zero (NRZ) coding. Oscilloscopes typically offer dedicated software options for debugging and testing the communications interfaces for common standards such as I2C, UART or CAN. The R&S®RTx-K50 option expands the addressable range of interface standards by adding decoding capability for standardized and proprietary Manchester or NRZ coded buses. It allows customizable configuration of the protocol structure that has to be decoded.

Radio frequencies in bands around 28 GHz are being discussed as candidates for mobile communications of the fifth generation (5G). Beam steering will be a key feature in the context of 5G. It will be a major challenge to test the beam steering capabilities of base stations and user equipment in every phase from research and development through production. Conducted measurements will be mainly replaced by over-the-air measurements of electromagnetic radiation. Rohde & Schwarz offers the R&S®NRPM Over-the-Air (OTA) Power Measurement Solution that perfectly fits such measurement needs.Part of this solution are the R&S®NRPM-A66 antenna modules. They have integrated diode detectors. Thus, there are no cables between the antenna and the detector as in traditional setups. This avoids high and potentially unknown RF losses. The R&S®NRPM-A66 antenna modules with their integrated diode detectors are factory calibrated, which means that the user does not have to calibrate them to achieve highly accurate measurement results.This application note contains theoretical background on OTA power and pattern measurements. It gives step-by-step instructions for the verification of the power level and the radiation pattern of a device under test (DUT) in comparison to a golden device, and it presents an approach for verifying the accuracy of beam steering.
