Designing 5G and satellite communication systems requires tight design margins and timelines, complex modulation, and adherence to stringent standards. You’re facing a whole new set of design and test challenges, including wider bandwidths, higher frequencies, and greater system complexity. The M9484C VXG provides the industry’s first vector signal generator with up to 54 GHz frequency range and 2.5 GHz of modulation bandwidth in a single instrument, or up to 110 GHz with the V3080A frequency extender and 5 GHz with channel bonding, to enable your next breakthrough. 

  • Supports MIMO real-time fading for all 3GPP 5G NR base station conformance tests with PathWave Signal Generation software
  • Covers all 5G NR frequency bands and V- / W-band for satellite communications  
  • Generates complex wideband signals needed for carrier aggregation and digital pre-distortion (DPD) applications
  • Delivers superior RF performance for accurately characterizing devices under test, such as phase noise, error vector magnitude (EVM), and adjacent channel power ratio (ACPR)
  • Simplifies MIMO and beamforming test setups with up to 4 synchronized and phase-coherent channels in one instrument and more than 32 channels in multiple instruments
  • Streamlines complex receiver test scenarios with the world’s first 8-virtual-signal emulation per RF channel
