EW receiver mission data files can contain hundreds of emitters with thousands of modes and beams that must be tested by simulation at RF. Often, these emitters, their modes and beams are listed on intelligence databases and must be imported from a spreadsheet into to an emitter simulation application such as the R&S®Pulse Sequencer software. For this purpose, the R&S®Pulse Sequencer software offers an internal script editor which allows to import user data and automatically generate emitter, sequence or platform configurations that can then immediately be played into RF without any additional software. Furthermore, the R&S®Pulse Sequencer offers a SCPI recorder tool to collect manual entries during scenario data creation into a list of corresponding SCPI commands. This list of commands can easily be used to create user defined scripts that can either run in the internal script editor or an external software (e.g. Matlab, Python).

Automated Solution with High Efficiency
5G New Radio (NR) presents dramatic challenges to the testing of User Equipment (UE) Power Amplifier (PA). Multiple frequency bands, flexible 5G operation mode, multiple PA performance metrics and the MIPI control interface increases the potential PA testing workload significantly. Manually repeating these tests under so many different scenarios can be costly and time consuming. An automated testing solution can help the test engineer to highly improve the testing efficiency.In this application note, it introduces an example of automated testing of 5G UE PA with R&S signal generator, signal and spectrum analyzer, vector signal explorer software, power meter along with power supply.The entire application note is organized with following structure:Chapter 2 outlines the challenges to 5G UE PA testing.Chapter 3 introduces the setup for 5G signal generation and analysis. For 5G signal generation, a batch program of converting *.CSV files with IQ vectors to ARB waveform files is introduced. For 5G signal analysis, the R&S®VSE software is recommended, which enables the separation of RF signal collection and measurement to improve testing efficiency.Chapter 4 provides the informative content about the integration of MIPI control interface for the PA ON/OFF state switching and register configuration.Chapter 5 gives a guide on the implementation of a quick power servo, in which the techniques to speed up the PA power level adjustment are discussed.Chapter 6 summarizes the automated testing procedure.

This application note is based on collaborative work between Cadence and Rohde & Schwarz.The focus is on understanding as early as possible in the design process performance enhancements through linearization of non-linear devices, in our case the RF power amplifier (PA). In other words, what performance benefits can be reached with linearization techniques such as digital predistortion (DPD). Typically, this is investigated when the device is available and physical RF measurements are conducted. In this application note, it is looked at earlier in the design process while using electronic design automation (EDA) such as Cadence® AWR® Visual System Simulator™ (VSS) software. The goal is to allow an RF designer to evaluate the linearizability of his design without in-depth knowledge of DPD algorithms. In the end, the designer can get closer to the optimal efficiency with earlier access to DPD, while at the same time improving time-to-market.The application note brings code examples and an exemplary setup for VSS software to provide an easy start to replicate and use the described procedure.
