Multi-Standard Radio (MSR) Measurement Application

The MSR measurement application transforms the X-Series signal analyzers into standard-based MSR base station transmitter testers by adding fast one-button RF conformance measurements to help you evaluate and manufacture your MSR base station and base station components.

X-Series measurement applications can help you:

  • Gain more insight into device performance with intuitive display and graphs for your application. Select from our library of over 25 different measurement applications. 
  • Ensure that your design meets the latest standard. Updates are made to the X-Series measurement applications as standards evolve. 
  • Apply the same measurement science across multiple hardware platforms for consistent measurement results over your design cycle from R&D to production. 
  • Choose the license structure that meets your business needs. We provide a range of license types (node-locked, transportable, floating or USB portable) and license terms (perpetual or time-based).

Key features

  • Perform MSR base station transmitter tests on any combination of LTE FDD, WCDMA/HSPA/HSPA+ and GSM/EDGE/Evo Evolution signals (license required for each measurement application) 
  • Perform one-button tests per the 3GPP Release 10 standard 
  • (TR/TS 37 series) 
  • Use hardkey/softkey manual user interface or SCPI remote user interface 
  • Extend test assets with transportable licenses between X-series signal analyzers with multi-touch UI

Real-time spectrum analysis for MSR

Adding real-time spectrum analysis to a UXA, PXA or MXA signal analyzer addresses the measurement challenges associated with dynamic RF signals, such as bursted transmissions of GSM or LTE-TDD in an MSR signal configuration, and enables identification of interference caused by multiple signals of different radio access technologies transmitted in the same base station RF bandwidth.

  • Accurately observe power changes for an MSR signal within the real-time bandwidth 
  • Capture random interfering signals with durations as short as 3.57 μs 
  • Perform fast, wideband measurements without compromising performance

Multi-Standard Radio (MSR) Technology Overview

The rapid evolution of mobile broadband and the need to deploy next generation cellular technologies alongside legacy deployment has lead to development of multi-standard radio (MSR) base stations. 3GPP defines an MSR base station by the ability of its receiver and transmitter to process two or more carriers in common, active RF components simultaneously in a declared RF bandwidth, where at least one carrier is of a different radio access technology (RAT) than the other carrier(s). The key drivers behind MSR are coexistence of different technologies in a single network, spectrum “refarming,” and cost reduction. MSR allows operators to put spectrum space to a new use, resulting in seamless network migration from the currently deployed 2/3G radio formats to 4G. In terms of cost reduction, using the same base station hardware for multiple technologies reduces the number of sites, site rental costs, and the amount of on-site equipment required. Traditionally the RF specifications for base station transmitters and receivers have been developed separately for the different RATs. However, in an MSR base station, the base station transmitter and receiver is capable of simultaneously processing multiple carriers of different RATs using common RF hardware, requiring a new set of RF specifications. As such, 3GPP developed a dedicated RF specification for MSR-capable base stations in the 3GPP Release 9 and 10 (TR/TS 37 series). The operating bands for which MSR base stations are defined are divided into three different band categories (BCs): BC1 for LTE-FDD and W-CDMA operation; BC2 for LTE-FDD, W-CDMA and GSM/EDGE operation; and BC3 for LTE-TDD operation. MSR conformance tests are required when carriers of multiple RATs are being activated. This is done through a set of multi-RAT test configurations (TCs) of contiguous and non-contiguous frequency allocations. Required transmitter measurements in a multi-RAT configuration include channel power, modulation quality (EVM), frequency error, spurious emissions, and operating band unwanted emissions (SEM). Alternatively, ACLR occupied BW and time alignment between transmitter branches are performed in single-RAT configurations, as defined in the TS37.141 conformance requirements.
