verifying and debugging designs that
include A/Ds, D/As, DSPs and
embedded 8- or 16-bit microcontrollers.
These scopes give you the tools you
need to solve your mixed analog and
digital engineering challenges more
easily.

What makes these scopes so ideal for
mixed analog and digital analysis?
The 54600-series scopes combine three
critical features:

• 2 MB of MegaZoom deep memory

on each channel so you can capture
long, non-repeating signals, maintain
high sample rate and quickly zoom in
on areas of interest

• a revolutionary ultra-responsive,

high-definition display that's a clearer
"window into your world" – it lets
you see more signal detail than ever
before

• flexible triggering that lets you easily

isolate and analyze the complex
signals and fault conditions common
in mixed analog and digital designs.

This combination of capabilities is
tailored to give you the measurement
power you need to get your mixed
analog and digital job done faster.

At Agilent Technologies, we focus
on developing products that help
you do your job better. That's why
54600-Series scopes are optimized for
your needs and why they come in a
variety of configurations. Choose the
one that's right for your application and
your budget.

The Mixed Signal scopes
(models 54621D and 54622D):

The 60- and 100-MHz mixed-signal
oscilloscopes (MSOs), with 2 analog
channels and 16 digital channels,
uniquely combine the detailed signal
analysis of a scope with the multi­channel timing measurements of a logic
analyzer. They let you see the complex
interactions among your signals on up
to 18 channels at the same time.
No more guesswork and no more
poking around to see a few channels at
a time. These scopes can easily
conquer mixed analog and digital
debugging problems that a traditional
scope can't begin to address, because
they let you simultaneously test and
monitor the high-speed digital control
signals and the slower analog signals in

your design. The combination of analog
channels, digital timing channels and
MegaZoom deep memory with
triggering across all 18 channels
provides totally new ways to debug
mixed analog and digital 8- or 16-bit
microcontroller-based designs. Plus,
the MSOs are built on the same scope
foundation as the other 54600 models,
so they look and feel like a familiar
scope.

4-channel scope (model 54624A):

If your designs include heavy analog
content, the 100-MHz 54624A will give
you the channel count and measurement
power you need, including MegaZoom
deep memory, high definition display
and flexible triggering. Whether you're
testing designs with four inputs, such

as anti-lock brakes, or monitoring
multiple outputs of a power supply, the
4-channel model helps you get your
debug and verification done with ease.

2-channel scopes
(models 54621A and 54622A):

The two-channel models bring all the
benefits of MegaZoom deep memory,
high-definition display, and flexible
triggering to those value-minded
designers with lower channel
requirements. Available in both 60- and
100-MHz models, they give you an
affordable way to see long time periods
while maintaining high sample rate so
you can see details in your designs.

2 + 16 Channel Mixed Signal Oscilloscope (MSO)

MegaZoom Deep Memory

With 2 MB of MegaZoom deep memory
behind every channel, 54600-Series
scopes give you deep-memory capture
without the sluggish response and
complex operation you’ve had to
tolerate with other deep-memory
scopes. And unlike the alternatives,
MegaZoom deep memory is not a
special mode; it operates with the same
familiar controls you use for regular
scope measurements. That means it's
always available to help you do a better
job finding details buried in complex
signals, discovering anomalies in the
absence of good trigger events,
correlating high-speed digital control
signals with slower analog signals and
capturing infrequent events.

The dilemma of having to do two
captures to get a long time capture or
to see detailed resolution is solved with
MegaZoom deep memory as you can
have both with a single measurement.
Deep memory means that the sample
rate can be kept high even when you
capture long time periods. You’ll have
a hard time finding another scope that
easily lets you collect 10 milliseconds
of data with the ability to see
5 nanosecond details like you can with
MegaZoom deep memory.

Thanks to multiple processors
optimized for the task of signal
acquisition, storage and display, the
new 54600-Series scopes are the only
deep-memory scopes that respond
instantly to your control inputs, and
have fast, responsive displays and easy­to-use pan and zoom. Compare them to
other scopes in this price range – only
the 54600-Series gives you long time
capture and detailed resolution with
fast, easy MegaZoom pan and zoom.

Revolutionary high-definition display

When you combine MegaZoom deep
memory with a patented high-definition
display system, you get an accurate and
responsive "window into your world".
The MegaZoom deep memory is
mapped into 32 levels of gray scale on a
display which has superior horizontal
resolution. And because the screen
update rate is more than 25 times faster
than typical digital scopes, you get a
responsive display that reflects changes
in your waveform instantaneously – so
you see a more realistic representation
of your signals.

This revolutionary design gives you
more insight into your designs than
ever before. With deep memory and a
high-definition display system, 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 weeks to find with a
traditional scope.

The bright dot on the
high definition display
is a distortion in 1 of
the 1,500 pulses
captured in this single
shot measurement.
Simply dial in for a
closer look using
MegaZoom pan and
zoom, and you’ll see
the details that would
have escaped other
scopes, such as the
distortion in this
square wave.
This deep memory
and display system is
not a complex special
mode, either. It is
available on every
measurement pass
at full speed.

Flexible triggering

With mixed analog and digital designs,
sometimes it is hard to trace an anomaly
back to its root cause unless you can
trigger on it and correlate it with
another signal. With the 54600-Series
scopes, triggering is no longer a hassle.
They come with flexible triggering
capabilities (edge, pulse width, pattern,
TV, sequence, I

2

C and duration) across
all channels so you can easily isolate
and analyze complex signals and
interactions common in your mixed
analog and digital designs.

If you are working with micro­controllers that use I

2

C serial
communications, you'll be glad to
discover that 54600-Series scopes help
you fine-tune your debugging. Use I

2

C
trigger mode to first help verify your
inter-IC communication handshaking.
Then you can use the I

2

C trigger to
ensure that the correct data is being
transmitted to the desired device.
