Tektronix MDO4054B-3 Mixed Domain Oscilloscope

The Tektronix MDO4054B-3 Mixed Domain Oscilloscope provides 4 analog channels of 500 MHz bandwidth with a 700 ps rise time. This unit offers an RF channel frequency range from 9 kHz to 3 GHz. Time coordinated analog, digital and RF signal acquisitions are available in this single instrument. Solve complicated design issues quickly and efficiently with an oscilloscope integrated into your design. Observe the frequency domain, and correlate events with the time that domain phenomena caused them. The spectrum shown in the Frequency Domain view is taken from the period of time indicated by the short orange bar in the time domain view – known as the Spectrum Time. With the MDO4054B-3, Spectrum Time can be moved through the acquisition to investigate how the RF spectrum changes over time. And this can be done while the oscilloscope is live and running or on a stopped acquisition.

With traditional oscilloscope FFTs, you can typically either get the desired view of the FFT display, or the desired view of your other time domain signals of interest, but never both at the same time. This is because traditional oscilloscopes only have a single acquisition system with a single set of user settings such as record length, sample rate, and time per division that drive all data views. But with the Tektronix MDO4054B-3, the spectrum analyzer has its own acquisition system that is independent, but time correlated, to the analog and digital channel acquisition systems. This allows each domain to be configured optimally, providing a complete time correlated system view of all analog, digital, and RF signals of interest.
