R&S® MXO 4 Oscilloscope

R&S® MXO 4 Oscilloscope

Next generation oscilloscope for accelerated insight

Key facts

  • Bandwidth: 200 MHz – 1.5 GHz
  • World’s first oscilloscope with an update rate > 4.5 million waveforms per second
  • Industry-leading system architecture: 18-bit vertical resolution/12-bit ADC
  • Deepest in class standard memory: 400 Mpoints
  • Industry leading spectrum acquisition rate of 45,000 FFT/s


The R&S®MXO 4 series is the first of a new generation of oscilloscopes that excels in both performance and value. The instruments deliver a once-in-a-decade engineering breakthrough for accelerated insight.

They have the world’s fastest real-time update rate of 4.5 million waveforms/s, meaning engineers can see more infrequent events than with any other instrument. The 12-bit ADC in the R&S®MXO 4 series has 16 times the resolution of traditional 8-bit oscilloscopes at all sample rates for more precise measurements without any compromises. A standard 400 Mpoint acquisition memory on all four channels and an optional 800 Mpoint interleaved memory provide the instrument with up to 100 times the standard memory of comparable instruments.

A class above similar oscilloscopes, R&S®MXO 4 series oscilloscopes sport an impressive 13.3″ Full HD capacitive touchscreen and an intuitive user interface with a learning curve of less than 15 minutes.
