Introducing the Mixed Domain Oscilloscope
Introducing the world’s first and only oscilloscope with a built-in spectrum
analyzer. For the first time ever, you can capture time-correlated analog,
digital, and RF signals for a complete system view of your device. See both
the time and fre
quency doma in in a sing le glance. View the RF spectrum
at any point in time to see how it changes over time or with device state.
Solve the most complicated design issues, qu ickly and efficiently, with an
oscilloscope as integrated as your design.
Based on the industry-standard MSO4000B Oscilloscope Series, you can
now use your to ol of choice, the oscilloscope, to look at the frequency
domain rather than having to find and re-learn a spectrum analyzer.
However, the power of the MDO goes well beyond simply obse rving the
frequency do
main as you would on a spectrum analyzer. The real power is
in its ability to correlate events in the frequency domain with the time domain
phenomena that caused them.
When both the RF channel and any analog or digital channels are on, the
oscilloscope display is split into two views. The upper half of the display
is a traditional oscilloscope view of the Time Domain. The lower half of
the display is a Frequency Domain view of the RF input. Note that the
Frequency Domain view is not simply an FFT of the analog or digital
channels in t
he instrument, but is the spectrum acquired from the RF input.
The spectrum shown in the Frequency Domain view is taken from the period
of time indic
ated by the short orange bar in the time domain view – known
as the Spectrum Time. With the MDO4000 Series, 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.
The upper half of the MDO4000 Series display shows the Time Domain view of the analog
and digital channels, while the lower half shows the Frequency Domain view of the RF
channel. The orange bar – Spectrum Time – shows the period of time used to calculate
the RF spectrum.
Figures 1 through 4 show a simple everyday a pplication – tuning of a
VCO/PLL. This ap plication illustrates the powerful connection between the
time doma
in and the frequency domain that the MDO4000 Series provides.
With its wide capture bandwidth and ability to move Spectrum Time
throughout the acquisition, this single capture includes the same spectral
content as approximately 1,500 unique test setups and acq uisitions on a
traditional spectrum analyzer. For the first time ever, correlating events,
observing interactions, or measuring timing late ncies between the two
domains i
s exceptionally easy, giving you quick insight to your design’s
operation.
