Figure 2. 2 + 16-channel mixed signal oscilloscope (MSO) allows you to view analog and digital content on one instrument.
Mixed-signal scopes
(models 54621D, 54622D,
54641D, and 54642D)
The mixed-signal oscilloscopes
(MSO), with 2 analog channels
and 16 digital channels, uniquely
combine the detailed signal analy-
sis of a scope with the multi-
channel 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 guess-
work and no more poking around
to see a few channels at a time.
These scopes can easily conquer
mixed analog and digital debug-
ging problems that a traditional
scope can't begin to address,
because they let you simultane-
ously test and monitor the high-
speed digital control signals and
the slower analog signals in
your design.
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, 54622A,
54641A, and 54642A)
The 2-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. They
give you an affordable way to see
long time periods while maintain-
ing high sample rate so you can
see details in your designs.

Affordable and Responsive
MegaZoom deep memory
With 4 MB to 8 MB of MegaZoom
deep memory, 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.
That means it’s always available
to help you find details buried
in complex signals, discover
anomalies, correlate high-speed
digital control signals with slower
analog signals and capture
infrequent events.
The dilemma of having to trigger
twice 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 stays high even when captur-
ing long time periods.
The 54600-Series scopes are the
only deep-memory scopes that
respond instantly to your control
inputs with a fast, responsive
display. Compare them to other
scopes in this price range – only
the 54600-Series provides deep
memory at an affordable price.
Figure 3. 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 special mode; it is available on every measurement pass at full speed.

Affordable and Responsive (continued)
Revolutionary high-definition dis-
play helps you see details
Combine MegaZoom deep memory
with a patented high-definition
display system, and you will see
subtle details that most scopes
won’t show you. The MegaZoom
deep memory is mapped into 32
levels of intensity on a display
that has twice the horizontal
resolution and update rates of up
to 25 million vectors per second –
so you see a more realistic
representation of your signals.
There is less chance to miss a
narrow occasional transient, less
chance to miss a glitch or distort-
ed edge that impacts circuit
operation, and less chance to
miss all those subtle details that
can take weeks to find with a
traditional digital scope.
Standard features
Agilent 54600-Series scopes
include the standard features you
need to get your job done easier

N2758A CAN Trigger Module
• Trigger on CAN 2.0A/B message
frames with user specified IDs
and/or data
• Trigger on Error frames
• Differential CAN
• Acknowledge On/Off
• Built In QuickHelp
• Remote Control via GPIB/RS232
• Compatible with 54621D, 54622D,
54641D, 54642D
The N2758A CAN trigger module
extends your Mixed Signal
Oscilloscope’s (MSO) capabilities
beyond the standard CAN SOF
trigger. The module enables the
MSO to isolate and trigger on a
particular frame’s content. This
triggering allows you to:
• sort through frame traffic on
the bus
• isolate frames of interest
• specify particular frame
characteristics
• trigger and measure latency
between CAN frames meeting
the user specification
The CAN trigger module is ideal
for analyzing all traffic on the
broadcast network. Quickly find
frames that meet the specifica-
tions you select with an isolating
capability similar to pattern
triggering across multiple
channels in the parallel domain.
Synchronize to the particular
frame then examine the system
behavior of interest.

1-800-452-4844 or by visiting
our website at:
www.agilent.com/find/mso
The N2758A kit includes the CAN trigger module, digital cable, ten grabbers, and
two probe ground leads.
The N2758A CAN trigger module reduces the time required to
debug your mixed signal CAN based designs.

Triggering
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 across all
channels so you can easily isolate
and analyze complex signals and
interactions common in your
mixed analog and digital designs.
CAN, LIN, and USB Triggering
Controller Area Network (CAN)
and Universal Serial Bus (USB)
triggering comes standard with
the 54600-Series scopes. These
triggering modes make it easy to
synchronize CAN, LIN, and USB
frames. Don’t waste time finding
the start of the complex frames –
let Agilent do it for you.
CAN triggering synchronizes to
the start of a CAN frame on any
CAN high or CAN low signal.
Trigger on LIN (local interconnect
network) sync break at the begin-
ning of a message frame.
Figure 5. Easily synchronize to a
USB packet.
Figure 6. Make your automotive and industrial testing easier.
CAN triggering synchronizes to the start of a CAN frame on any
CAN high or CAN low signal.
USB is quickly becoming the
connection of choice for PC
peripherals. Make your testing
easy with Start of Packet (SOP),
End of Packet (EOP), Reset
Complete (RC), Enter Suspend,
or Exit Suspend modes.
The N2758A CAN trigger module
option enables the MSO to isolate
and trigger on a particular
frame’s content. For more
information , see page 7.

Triggering (continued)
I2C and SPI Triggering
Don’t spend your time sorting
through communication frames to
find the one of interest. Let
Agilent set up an Inter-Integrated
Circuit (I2C) or Serial Peripheral
Interface (SPI) trigger to sift
through the frames for you. And
like the CAN, LIN, and USB trig-
gers, I2C and SPI come standard
with the 54600-Series scopes.
Microcontroller and
DSP Applications
Microcontrollers (MCUs) and
Digital Signal Processors (DSPs)
are here to stay, and are becoming
more pervasive in industrial,
communications, automobile, and
consumer products. Design engi-
neers must grapple with scopes
that were not developed to tackle
the mixed analog and digital
signals found in MCU- and
DSP-based designs. Many engi-
neers, who rely primarily on
typical 2-channel or 4-channel
scopes in mixed analog and digi-
tal signal verification and debug,
find these scopes to be inade-

The full range of I2C triggering
includes start or stop condition,

write. SPI triggering allows for

and user-definable number of
bits per frame, as well as data
patterns.
quate when it comes to the chan-
nel count, memory depth, display
and triggering. The interactions
that occur in typical mixed analog
and digital design — taking a real-
world signal such as audio, video,
temperature or pressure, per-
forming some transformation on
the signal, and finally returning
that signal to the real world —
require more viewing capability
than current scopes can provide.
Agilent 54621D, 54622D, 54641D,
and 54642D mixed-signal
oscillscopes (MSOs) provide the
channel count, memory depth,
high-definition display, and
triggering that MCU and DSP
designs demand.
Figure 9. The 350 MHz and 500 MHz MSOs
are a great fit for DSP applications.
