Mixed Domain Ocilloscopes (MDO)

MDO Oscilloscope

Mixed-domain oscilloscopes (MDO) are digital oscilloscopes that incorporate an integrated spectrum analyzer that allow you to view both the time domain and the frequency domain simultaneously.

In this way, you can capture time-correlated analog, digital and RF signals at once using a universal trigger and data acquisition system. Of interest is seeing how the frequency spectrum is changing over time.

Many stand-alone spectrum analyzers are narrowband, showing you only a small portion of your spectrum at any point in time. MDO scopes have up to a 3 GHz capture bandwidth. Currently only Tektronix makes MDO scopes.
