  • Spectrum Management – Find Interference and Unknown Signals
  • Radar/EW – Full Characterization of Pulsed and Hopping Systems Characterize Radar and Pulsed RF Signals
  • RF Debug – Components, Modules, and Systems
  • Radio/Satellite Communications – Analyze Time-variant Behavior of Cognitive Radio and Software-defined Radio Systems
  • EMI Diagnostics – Increase Confidence that Designs will Pass Compliance Testing

The RSA6120A replaces conventional high-performance signal analyzers, offering the measurement confidence and functionality you demand for everyday tasks. A typical 20 dBm TOI and –151 dBm/Hz DANL at 2 GHz gives you the dynamic range you expect for challenging spectrum analysis measurements. All analysis is fully preselected and image free. The RSA6000 Series uses broadband preselection filters that are always in the signal path. You never have to compromise between dynamic range and analysis bandwidth by ‘switching out the preselector’.

A complete toolset of power and signal statistics measurements is standard, including Channel Power, ACLR, CCDF, Occupied Bandwidth, AM/FM/PM, and Spurious measurements. Available Phase Noise and General Purpose Modulation Analysis measurements round out the expected set of high-performance analysis tools.
