N9080C LTE/LTE-Advanced FDD measurement application provides a variety of one-touch transmitter measurements on X-Series signal analyzers with multi-touch user interface for LTE and LTE-Advanced FDD base station (eNB) and user equipment (UE).


The N9080C LTE/LTE-Advanced FDD application includes proven, ready-to-use measurements. Capturing measurement expertise and delivering repeatable results, the application lets you see and understand the performance of your LTE/LTE-Advanced FDD or NB-IoT/eMTC base station (eNB) and user equipment devices and designs. Gain confidence from proven algorithms and outstanding accuracy at every performance point with X-Series signal analyzers and the multi-touch UI. The N9080C is discontinued after June 1, 2019. The replacement model is the N9080EM0E X-Series Measurement Application with KeysightCare.

Signal analysis

  • LTE and LTE-Advanced FDD per 3GPP release 8 to 12
  • NB-IoT and eMTC per 3GPP release 13
  • Uplink and downlink RF transmitter conformance measurements in a single option
  • Pre-defined E-UTRA Test Configurations for multi-carrier (MC) and carrier aggregation (CA)
  • View and analyze up to five component carriers (CCs) simultaneously in both contiguous and non-contiguous configurations
  • Improved spectral efficiency with higher order demodulation to 256QAM


  • Output power level: channel power
  • Transmitted signal quality: EVM, frequency error, time alignment error, RSTP, OSTP, I/Q offset and more. Pinpoint signal impairments with color-coded traces like EVM vs. symbol, EVM vs. subcarrier, detected allocations (subcarrier vs. symbol), constellation diagram, and frame summary
  • Unwanted emissions: SEM, cumulative SEM, ACLR, cumulative ACLR (CACLR), OBW, spurious emissions, transmitter intermodulation
  • All measurements are available for single carrier (LTE) and multi-carrier/CA (LTE-Advanced) with contiguous and non-contiguous allocations as defined by 3GPP

RF transmitter testing

  • Simplify measurement setup with automatic detection of downlink channels and signals. For eNB conformance testing, measurement is simplified by recalling E-TM presets, for each carrier, according to 3GPP TS 36.141 conformance document.
  • Perform measurement on all LTE/LTE-Advanced FDD channel bandwidths with ability to view measured results – of up to 5 CCs for LTE-Advanced- in multiple domains such as resource block, sub-carrier, slot, or symbol. Graphical displays with color coding and marker coupling allows you to search for problems faster and troubleshoot the found problems quicker.
  • Test beyond physical layer by using the transport layer decoding functionality. Troubleshoot transport layer problems and verify the channel encoding is correct by getting access to data at different points in the receiver chain such as: demapped, deinterleaved, descrambled, deratematched and decoded data.
  • Add real-time spectrum analyzer (RTSA) capability to the UXA, PXA or MXA signal analyzers to pinpoint interference caused by other transmitters in the operating band or other events such as cross-modulation of component carriers in the transmitter.
