A built-in spectrum analyzer

Whether you’re a spectrum analyzer expert or an occasional user, you’ll be able to put the built-in spectrum analyzer right to work. Unlike other oscilloscopes that offer FFT “spectrum analysis”, the MDO3 Series has a true spectrum analyzer built right in.

  • 1 GHz or 3 GHz built-in spectrum analyzer options
  • Industry’s only true integrated spectrum analyzer hardware
  • Ultra-wide capture bandwidth up to 3 GHz
