Data Sheet
Easily see what's happening in your mixed analog and digital designs!
• Unique 2 + 16-channel MSO and 2- or 4-channel models
• 2 MB of MegaZoom deep memory per channel
• Patented high-definition display system
• Flexible triggering including I2C
• 60- and 100-MHz, 200 MSa/s
Multiple configurations to meet your needs
If you work with both analog and digital components, Agilent-Technologies 54600-Series oscilloscopes can help you easily see more of what's going on in your designs. The unique 2+16-channel mixed signal oscilloscope (MSO) models and the traditional 2- and 4-channel models are optimized with just the capabilities you need for 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.

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.
