About the 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.
Frequently asked questions
Which oscilloscopes does the MDO3SA fit?
Any model in the Tektronix MDO3000 series, from the 100 MHz MDO3012/MDO3014 to the 1 GHz MDO3102/MDO3104.
Does the upgrade change the oscilloscope bandwidth?
No. It only extends the spectrum analyzer input to 9 kHz - 3 GHz; the analog oscilloscope bandwidth is upgraded separately.
Is the key needed after the upgrade?
No. Tektronix describes it as a one-time, permanent upgrade enabled through a single-use hardware key, which is not required after the feature is enabled. A key that has already been used on one oscilloscope cannot be expected to upgrade another.
