The LTE TDD measurement application is one in a common library of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. Transforming the X-Series signal analyzers into standard-based transmitter testers, the application provides RF conformance measurements to help you design, evaluate, and manufacture your LTE FDD base station and user equipment devices. The measurement application closely follows the 3GPP standard, allowing you to stay on the leading edge of your design and manufacturing challenges.

RF transmitter testing

  • Low-cost alternative to the EXA economy class signal analyzer especially in mobile station component development and home base station (femtocell) manufacturing
  • Simplify measurement setup with automatic detection of downlink channels and signals. For eNB conformance testing, measurement is simplified by recalling E-TM presets according to 3GPP TS 36.141 conformance document 
  • Perform measurements on all LTE channel bandwidths, as well as all channels and signals, with the ability to view measured results by resource block, sub-carrier, slot, or symbol. Graphical displays with color coding and marker coupling allow you to search for problems faster and troubleshoot the found problems quicker 
  • For manufacturing, “conformance EVM” measurement provides up to 2x speed improvement over the traditional EVM measurement
