See and understand the performance of your W-CDMA/HSPA/HSPA+ base station (eNB) and user equipment (UE) devices and designs


The N9073C W-CDMA/HSPA+ measurement application’s proven, ready-to-use measurements capture expertise and deliver repeatable results. Gain confidence from proven algorithms and outstanding accuracy with every X-Series signal analyzer. The multi-touch user interface allows in-depth analysis from R&D to manufacturing of base station and user equipment devices. The N9073C is discontinued after June 1, 2019. The replacement model is the N9073EM0E X-Series Measurement Application with KeysightCare.

Signal analysis

  • W-CDMA, HSPA, HSPA+ per 3GPP TS 25 standard
  • Uplink and downlink RF transmitter measurements; analog baseband measurements with PXA BBIQ or MXA BBIQ hardware
  • One-touch measurements with pass/fail per the standard
  • Runs inside UXA, PXA, MXA, EXA and CXA signal analyzers with multi-touch UI


  • Downlink: EVM, frequency error, CPICH power accuracy, 64QAM RCDE, SEM, ACLR and more
  • Uplink: EVM, frequency error, PkCDE, RCDE, PRACH power, slot power, SEM, ACLR and more
  • Automatic detection of scrambling code, all active channels and signals plus predefined test models (TM1 to TM6)
  • Multiple result views: constellation diagram, code domain, numeric display, spectrum, time domain


RF transmitter testing

  • Ensure proper measurements and accurate results with built-in expertise and one-touch operation for both downlink and uplink with pass/fail limits in accordance with 3GPP TS25.141 and TS34.121 specifications.
  • Perform adjacent channel power measurement over wide dynamic range. With the UXA/PXA’s industry-leading dynamic range (up to –88 dBc) you can perform single-carrier and multi-carrier ACLR measurements on base station systems
  • Characterize your UE device using the uplink power control measurement. The power control measurement includes: slot power, PRACH power and slot phase. In addition to slot power, slot phase measures phase error, frequency error and EVM of uplink slots which can also be used for 3GPP UE phase discontinuity.
