The R&S®EX-IQ-Box plus a signal analyzer from enable the reliable analysis of digital baseband components.

The R&S EX-IQ-Box serves as a digital baseband interface between a device under test (DUT) and Rohde & Schwarz generators, analyzers and radio communication testers. The DigIConf software supplied with the device controls up to four R&S EX-IQ-Boxes in a test setup and can thus output IQ data for feeding into a DUT while simultaneously receiving IQ output from a DUT.To work together smoothly, the DUT, the R&S EX-IQ-Box and the R&S test instruments have to be configured properly. The purpose of Application Note 1MA168 is to introduce the right 'initial steps' required to get started successfully.

This application note explains how to bring a CADENCE system which is attached to an R&S EX-IQ-BOX into service for the first time. The first part of the document shows how to setup an LTE Demo without using a UE design. This setup uses the R&S CMW500 as the downlink transmitter. The emulator receives the downlink via an R&S EX-IQBOX and passes it to an R&S spectrum analyzer (R&S FSx) via a second R&S EXIQ-BOX. The second part describes the real wiring using up- and downlink. This will only work if a UE design is available on the emulator.

During the design process of chipsets or modules, FPGA-based hardware emulators are utilized to perform early tests with real test and measurement instruments. These hardware emulators usually run at artificially reduced speed, but apart from that function like the finished design. In this application note we explain how to test FPGA-based hardware emulators using Rohde & Schwarz vector signal generators for creating suitable real-time test signals at reduced sample rates. We further explain how to correctly adapt AWGN signal generation and fading simulation for “slow I/Q”.

Your measurement task: To analyze an RF module via its digital interface. This Application Note explains how. As interfaces between the baseband and the RF modules of mobile radio base stations and terminals are increasingly digital, instruments for testing such modules need digital baseband interfaces as well. The R&S®EX-IQ-Box is a digital interface adapter that provides digital baseband I/O for Rohde & Schwarz signal generators and signal analyzers. An R&S signal analyzer with digital baseband interface R&S®FSQ-B17 can analyze digital baseband components input from the R&S®EX-IQ-Box. Data collected with a test-setup consisting of an R&S signal analyzer and the digital interface adapter R&S®EX-IQ-Box can be used in an Agilent ADS environment. For details of how to input the results to ADS, see Application Note 1MA72: 'Using R&S® Instruments within Agilent®ADS®Software'
