It is frequently desired to process the results stored on the floppy on a PC, eg for the generation of customer-specific test reports by means of a word processing system. To enable processing on an external PC, the binary data usually need conversion into an ASCII format. This is possible by means of the ESXS2ASC.EXE program. The program is available free of charge from your Rohde & Schwarz representative.

Long Term Evolution (LTE) technology has become the technology of choice for keeping up with the requirement of higher throughput in mobile communication in bands below 6 GHz. It is expected that within the next decade LTE will become the primary commercial standard. LTE is often used to broadcast emergency information in times of natural disasters and national crises and is under investigation for further end use application in government as well as military application fields.Communication via LTE has some vulnerabilities. This drawback is a matter of concern since it is possible to completely take down the LTE network or at least partially block communication, intentionally with the help of jamming signals, or unintentionally through various forms of interference.An example of unintentional interference issues is the frequently discussed co-existence issues with Air Traffic Control (ATC) S-band radar and Digital TV bands. The in-device co-existence challenge is also a potentially important issue with the rapid evolution of multi-standard radios.This White Paper will focus on the vulnerabilities of LTE communication by explaining LTE jamming and unintentional interference problems, address the coexistence issues with other services, and discuss the mitigation options to build a broad perspective on the possible deployment of the LTE technology for future military and civil governmental applications.Understanding the susceptance of new technologies to known and expected environments is critical to the adoption for defense applications

In contrast to standardized digital interfaces which are customary for communication between audio devices, diverse data formats are used between the internal modules of a particular device. The I²S interface developed by Philips has now been widely adopted for the latter. The data structure of this digital audio interface and the adaptation of Audio Analyzer UPD in the different operating modes of the I²S bus are described in this Application Note.

High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) optimize UMTS for packet data services in downlink and uplink, respectively. Together, they are referred to as High Speed Packet Access (HSPA). Within 3GPP Release 7, 8, 9 and 10, further improvements to HSPA have been specified in the context of HSPA+ or HSPA evolution. This White Paper introduces key features of HSPA+ and outlines the changes to the radio interface.

I/Q waveform files contain the digital complex sample values of a radio signal. They can be synthetically computer-calculated for generating precisely defined contents, or they can represent the recording of a received live signal. The structure of these files has never been standardized, which is why so many different formats are in use today. R&S®IQ Converter and R&S®IQ Stream Extractor are programs that quickly and conveniently convert the contents of I/Q waveform files of nearly any structure into the I/Q format used by the R&S®BTC, R&S®CLG, R&S®SLG, R&S®SFU, R&S®SFE and R&S®SFE100 signal generators. This makes it possible for the signal generators to use their integrated ARB function to generate precise RF signals from nearly any I/Q waveform file.

A simple concept with Azure IoT
Cloud development, microservice architectures and container virtualization are becoming more and more standard. Software components are repacked into containers, networked with each other and then brought into the cloud. The topic is also becoming increasingly interesting for test & measurement.But how do you connect your existing measurement equipment to the cloud, with instruments in some cases not even having an internet connection?This document describes an approach how to establish a remote connection between the instrument and the cloud using an IoT broker. The implementation is done using an Azure IoT Hub and software in .NET Core.
