MDO3SA

The MDO3SA is a post-purchase upgrade for Tektronix MDO3000 series mixed domain oscilloscopes. Every MDO3000 has a built-in spectrum analyzer whose frequency range runs from 9 kHz up to the oscilloscope's analog bandwidth (100 MHz to 1 GHz depending on model). The MDO3SA extends that input range to 9 kHz - 3 GHz on any model and raises the capture bandwidth to 3 GHz.

With the wider range the MDO3000 can look at most consumer wireless standards, such as 2.4 GHz signals, from the dedicated spectrum analyzer input, in a full-screen frequency domain view with the usual center frequency, span, reference level and resolution bandwidth settings.

The upgrade is delivered on an application module hardware key. Tektronix describes it as a one-time, permanent upgrade: the single-use key enables the feature and is then no longer needed. Tektronix has made the 3 Series MDO the recommended replacement for the MDO3000 series, whose supply it describes as limited.
