3. RF Acquisition time: This is the amount
of time acquired by the RF system.
At mid-to-fast time base settings, it
equals analog time. At slower time base
settings, it can be less than analog time.
In the
fi gure to the right, it is shown by
a pair of brackets around the spectrum
time.
Panning Spectrum Time Through Analog Time
One of the most powerful features of the MDO4000 series is its ability to move spectrum time through analog time. This
allows you to see how the spectrum changes over time and how it changes relative to other analog signals, digital signals,
or serial/parallel bus commands.
Move spectrum time through analog time by
rotating the Wave Inspector pan (outer) knob.
When the oscilloscope is acquiring data
(running) and you are rotating the pan
control, you can move spectrum time and
RF acquisition time simultaneously. The
operation works as if you were dragging the
RF acquisition time along with the spectrum
time.
