Revolutionary high-definition color
display helps you see subtle
details that most scopes can’t
show you
Combine MegaZoom III
deep memory with an ultra
high-definition color display
system, and you will see subtle
details that most scopes won’t
show you. The MegaZoom III deep
memory is mapped to 256 levels
of intensity on a display that has
industry-leading XGA resolution
(1024 x 768 lines) and phenomenal
waveform update rates of up to
100,000 waveforms per second in
the default real-time acquisition
mode – so you see a more realistic
representation of your signals.
With fast waveform update rates,
your scope has less dead time
between the acquisitions. Why
is it important to minimize
dead time? Capturing a random,
infrequent glitch can be difficult,
because you can’t predict when
the glitch will occur. If it occurs
during the scope’s dead time, you
will miss it. By minimizing the
dead time, you can improve the
probability of the glitch occurring
during the acquisition time.
With a real-time waveform update
rate of up to 100,000 waveforms
per second, there is less chance
to miss a narrow occasional
transient, less chance to miss
a glitch or distorted edge that
impacts circuit operation, and
less chance to miss all those
subtle details that can take
days or weeks to find with a
traditional digital scope.
Agilent’s 6000 Series scopes
provide the fastest waveform
update rates in their class and
you do not need to select special
operating modes that may
entail tradeoffs in performance
and functionality. And with
MegaZoom III deep memory and
16 logic channels available in
MSO models, finding the root
cause of intermittent failures in
your embedded design becomes a
much easier task.
