Touch, Discover, Solve
The InfiniiVision 3000A X-Series redefined oscilloscopes. It saw the most signal detail, provided more functionality than any other oscilloscope, and gave you maximum investment protection. It was also the most successful oscilloscope in Hewlett Packard, Agilent and Keysight Technologies, Inc.’s history. The 3000T X-Series continues that legacy.
The 3000T X-Series takes everything that was revolutionary about the A model and adds a capacitive touch screen, a user interface designed for touch, and the exclusive Zone touch trigger, all combined with an industry-leading uncompromised update rate of 1 million wfm/s to give you the confidence that you’re seeing all of your signal detail, and the ability to discover any issues. And the addition of new analysis capabilities help you solve your hardest problems quickly.
The 3000T X-Series once again redefines what you can expect in a general purpose oscilloscope by providing all of the performance and capability you need to get to measurement insights faster:

Touch: Designed-for-touch interface and capacitive touch screen simplify use
From the start of product development, we designed every aspect of this oscilloscope to be seamlessly driven by a touch interface. Large, easy-to-touch targets, a graphical user interface that adapts to show you more and be easier to touch, and a large, sensitive, capacitive touch screen all combine to make operation quick and natural, just like your favorite tablet devices.
Capacitive touch screen technology enables productivity
The user interface allows you to use the alphanumeric pad for quick annotation, place waveforms or cursors in exact positions and drag docking panels across the screen to see more measurement information.
The 3000T X-Series offers three ways to access key menus and features: touch GUI for those that prefer tablet or smart phone touch interfaces, front panel buttons and knobs for the traditional oscilloscope users, and Keysight Insight pull down menu for users who prefer Windows-like operations. The 3000T X-Series also offers a “touch off” button as well as USB mouse and keyboard support.
Touch interface simplifies documentation
The availability of up to 4 annotations on screen makes it easy to highlight key items on screen shots. Streamline documentation with the ability to input information via a pop-up soft keyboard on the touch screen or a USB keyboard. A sidebar displays additional information without covering the waveform graticule, and allows you to dock and scroll through multiple measurement values. Touch gestures (like clicking) make navigating lists or moving between segment waveforms easy.
In addition to the beneits of touch, free BenchVue software provides documentation across multiple instruments at once. USB, LAN (optional) and GPIB (optional) connectivity make oscilloscope control or pulling data and screenshots easy. And the built-in ability to send emails when connected to the LAN allows you to email yourself a screenshot or data ile with just the press of a button.
Redefine your remote Web control oscilloscope experience.
The 3000T X-Series offers traditional control via a PC Web browser, but also supports remote control through popular tablet devices when using the optional LAN/VGA interface.
Discover: The industry’s fastest uncompromised update rate increases the chance of inding anomalies
Industry-Leading Uncompromised Update Rate
If you can’t see the problem, you can’t ix the problem. With an industry-leading update rate of over one million waveforms per second, the InfiniiVision 3000T X-Series gives you the highest probability of capturing random and infrequent events that you would miss on an oscilloscope with a lower waveform update rate.
Powered by MegaZoom IV smart memory technology, the InfiniiVision 3000T X-Series not only lets you see more waveforms, but it has the uncompromised ability to ind the most difficult problems in your design under any conditions. Unlike other oscilloscopes, uncompromised ability means:
- Always-fast, responsive operation
- No slowdown with logic channels on
- No slowdown with protocol decoding on
- No slowdown with math functions on
- No slowdown with measurements on
- No slowdown with vectors on
- No slowdown with sinx/x interpolation on
What is waveform update rate?
As oscilloscopes acquire data, process it, and plot it to the screen, there is inevitable “dead time,” or the time oscilloscopes miss signals completely. In general, the faster the waveform update rate, the shorter the dead time. The shorter the dead time, the more likely an oscilloscope is to capture anomalies and infrequent events. This is why it is important to select an oscilloscope with a fast waveform update rate. Figures 7 and 8 demonstrate the difference between a slower update rate and a faster update rate.
Many vendors claim an update rate specification, but that is only in a special mode, or without any features turned on. Table 1 shows the 3000T X-Series’ update rate versus a competing oscilloscope.
While all scopes update rate will vary to some degree by the timebase setting, it is critical that the update rate remain constant regardless of the functionality you are using within the oscilloscope.

Why is an uncompromised update rate important?
When debugging or troubleshooting a project, it is important that you see as much signal detail as possible. A fast update rate is just part of the overall equation to determine the likelihood of seeing an anomaly. The frequency of the anomaly, the timebase setting of the oscilloscope and the amount of time you allow the oscilloscope to see the anomaly all come in to play:
Pt = 100 x (1-[1-RW] (U x t) )
where
Pt = Probability of capturing anomaly in “t” seconds
t = Observation time
U = Scope’s measured waveform update rate
R = Anomalous event occurance rate
W = Display acquisition window = Timebase setting x 10
Therefore, it is important to select an oscilloscope with the fastest uncompromised update rate to allow enough time to increase your chances of seeing the glitch. In Table 1, in addition to the measured update rate, we show the probability of seeing a glitch that happens 5 times a second while allowing the oscilloscope to acquire for 5 seconds. With the 3000T X-Series you maximize your chances of seeing the infrequent glitch. With the competing scope, if you are using any of the other features like measurements, or search or digital channels, the update rate slows considerably. The only option you have in this case is to allow the oscilloscope to run longer. For example, if you are using digital channels you’ll have to let the scope run over 8,000 times longer to get a similar probability to the uncompromised update rate of the 3000T X-Series. That’s almost 12 hours of time versus 5 seconds!
MegaZoom IV smart memory technology enables uncompromised update rate
Traditionally, CPU processing was the major bottleneck for oscilloscope waveform update rate and responsiveness. Typically, the CPU handles interpolations, logic channel plotting, serial bus decoding, measurements and more, and the waveform update rate drops dramatically as these features are turned on.
The InfiniiVision 3000T X-Series requires minimum support from a CPU, as most core operations are handled by Keysight proprietary technology, the MegaZoom IV smart memory ASIC. MegaZoom includes hardware serial decoders and hardware mask/limit testing capability, plots analog and digital data directly to the display, supports GUI operation, and integrates additional instruments like the WaveGen function/arbitrary waveform generator.
Discover: Excellent signal integrity allows you to see more signal detail
The 3000T X-Series has excellent signal integrity, including full bandwidth to 1 mV/div and the ability to get up to 12-bits of resolution using the high resolution acquisition mode.
Other oscilloscopes in this class limit their bandwidth at smaller volt per division settings without notifying the user. This is likely to keep the noise acceptable at lower volt per division settings. Table 2 shows a comparison of noise.
Discover: Industry exclusive zone touch trigger makes triggering simple
An uncompromised update rate allows you to see an anomaly, but to continue the debug process you have to isolate it. Setting up a trigger has been a challenge since oscilloscopes introduced a triggered waveform. While oscilloscopes have added more and more triggering capability over the years, setting up triggers has remained complex at best and impossible at worst.
Zone touch trigger eliminates the complexity of setting up advanced triggers. Now, if you can see the event on the display of the oscilloscope, you can trigger on it just by drawing a box on the signal you want to isolate.
Discover: Standard segmented smart memory allows you to capture longer periods of time at high sample rates
Acquisition memory size is an essential oscilloscope specification because it determines sustainable sample rate and the amount of time you can capture in a single acquisition. In general, longer memory is better. However, no memory will always be long enough to capture all the signals you need, especially when capturing infrequent anomalies, data bursts, or multiple serial bus packets. Segmented memory acquisition lets you selectively capture and store important signal activity without capturing unimportant signal idle time. In addition, it provides a time stamp of each segment relative to the irst trigger event to enable analysis of the frequency of the event. Segmented memory comes standard on the 3000T X-Series.
Figure 13 shows segmented memory successfully capturing 100 small and large glitch events at 5 GSa/s in 47 seconds. Traditional memory architecture would require almost 203 Gpts of memory to accomplish the same result! This memory is not available on any scope in the market.
Discover: Dedicated search and navigation helps you navigate deep memory
Parametric and serial bus search and navigation comes standard on the 3000T X-Series oscilloscopes. When you are capturing long, complex waveforms using an oscilloscope’s acquisition memory, manually scrolling through stored waveform data to ind specific events of interest can be slow and cumbersome. With automatic search and navigation capability, you can easily set up specific search criteria and then quickly navigate to “found and marked” events. Available search criteria include edges, pulse width (time-qualified), rise/fall times (time-qualified), runt pulses (time-and level-qualified), frequency peaks (FFT function, threshold and excursion qualified), and serial bus frames, packets, and errors.
Solve: Integrated hardware-based serial decoding and triggering (option) makes easy work of low speed serial buses
Keysight InfiniiVision oscilloscopes, including the new 3000T X-Series, use hardware-based serial protocol decoding. Some other vendors use software post-processing techniques to decode serial packets⁄ frames, and therefore have slow waveform and decode capture rates and could miss critical events and errors due to a long dead-time. Faster decoding with hardware-based technology enhances the probability of capturing infrequent serial communication errors.
After capturing serial bus communication, you can easily perform a search operation based on specific criteria and then quickly navigate to bytes/frames of serial data that satisfy that search criteria. The 3000T X-Series can decode two serial buses simultaneously using hardware based decoding, and display the captured data in a time interleaved “lister” display.
Serial protocol decoding can be used simultaneously with segmented memory and Zone touch triggering. The 3000T X-Series has the most decode/trigger options in this class of instrument including: I2C, SPI, RS232/422/485/UART, CAN, CAN-FD, CAN-dbc, LIN, SENT, FlexRay, MIL-STD 1553, ARINC 429, and I2S.
Solve: Segmented smart memory combined with protocol analysis enables insights over long periods of time
Segmented memory works in conjunction with any of the optional serial protocol decodes. For example, by setting the trigger condition to “SENT serial bus error,” segmented memory captures and stores only SENT pulse period error packets and stitches together each segment for easy viewing of the decoded data in the lister. You can quickly compare time tags to discover time intervals between errors.
Solve: Dedicated frequency/spectrum analysis allows you to time-correlate analog, digital, and frequency domain signals in a single instrument
Viewing the frequency content of waveforms is greatly simplified by a dedicated FFT button and level adjustment knobs. Pop up keypads make inputting start, stop, span and center frequency easy. And the new problem solving feature called “gated FFT”, unique in this class of instrument, lets you time correlate the analog, digital, and frequency domain to aid in analysis and debug. In addition, there are new capabilities for peak searching, max and min hold and averaging of FFTs to increase dynamic range.
When gated FFT is on, the oscilloscope goes into zoom mode. The FFT analysis shown in the zoomed (bottom) window is taken from the period of time indicated by the zoom box in the main (top) window. In the gated FFT mode, touch and lick the zoom box through the acquisition to investigate how the FFT analysis changes over time, correlating the RF phenomenon with the analog and digital phenomenon.
Figure 21a through 21d show a simple gated FFT example observing a RF signal frequency transition from 400 MHz to 200 MHz, time correlated to both the SPI controlling signal (digital) and a VCO enable signal (analog). Note, you can also visualize the RF signal itself in the time domain to gain additional insight such as a gap in the RF time domain waveform.
Solve: Standard advanced math capabilities allow new views of signals
Advanced math analysis provides a variety of additional math functions and comes standard on the 3000T X-Series. Additionally, math functions can be nested to provide additional insight into your designs. You can create up to two math functions, with one math function and FFT displayed at a time.

Solve: 6-in-1 integration allows new measurement possibilities
In addition to the class leading oscilloscope and powerful serial protocol analysis capabilities, the 3000T X-Series offers four additional integrated instrument capabilities not always found in this class of oscilloscope.
Integrated mixed signal oscilloscope (MSO - optional)
The 3000T X-Series offers 16 optional, integrated and upgradable digital channels. Digital content is everywhere in today’s designs and traditional 2 and 4 channel oscilloscopes do not always provide enough channels for the job at hand.
With an additional 16 integrated digital channels, you now have up to 20 channels of time-correlated acquisition and viewing on the same instrument. In addition to offering powerful triggering across the analog and digital channels, this also gives you additional channels to use for serial decode and triggering. And if you buy a 2 or 4 channel DSO, you can upgrade it at any time to an MSO with a software license.
Integrated WaveGen: Built-in 20 MHz function/arbitrary waveform generator (optional)
The 3000T X-Series offers an integrated 20 MHz function/arbitrary waveform generator, available with modulation support (DSOX3WAVEGEN). The function generator provides stimulus output of sine, square, ramp, pulse, DC, Sinc (x), exponential rise/fall, cardiac, Gaussian Pulse and noise waveforms to your device under test. The modulation feature supports AM, FM, and FSK modulations with modulation shapes of sine, square, and ramp. With AWG functionality, you can store waveforms from analog channels or reference memory to the arbitrary memory and output from WaveGen. Then easily create or edit the waveform using the built-in editor via touch and the large screen or by using Keysight’s Benchlink Waveform Builder software: www.keysight.com/ind/33503.
Integrated frequency measurements: Optional 8-digit counter and totalizer
Traditional oscilloscope counter measurements offer only five or six digits of resolution, which may not be enough for the most critical frequency measurements are being made.
With the 3000T X-Series’ optional 8-digit counter (part of the DSOXT3DVMCTR option), you can see your measurements with the precision you would normally expect only from a standalone counter. Because the integrated counter measures frequencies up to a wide bandwidth of 1.0 GHz, you can use it for many high-frequency applications as well. If you are looking for the ultimate precision, you can connect your 3000T X-Series oscilloscope to your most trusted 10-MHz reference source to share a common 10-MHz clock.
The totalizer feature of the DSOXT3DVMCTR counter option adds another valuable capability to the oscilloscope. It can count the number of events (totalize), and it also can monitor the number of trigger-condition-qualified events. The trigger-qualified events totalizer does not require an actual trigger to occur. It only requires a trigger-satisfying event to take place. In other words, the totalizer can monitor events faster than the trigger rate of a scope, as fast as 25 million events per second (a function of the oscilloscope’s holdoff time, which has the minimum of 40 ns). Figures 27 shows example of a totalizer counting the number of CAN-FD CRC delimiter bit error packets that took place in a design.
Solve: Hardware accelerated mask/limit testing (option) makes it easy to see the performance of your device
Whether you are performing pass/fail tests to specified standards in manufacturing or testing for infrequent signal anomalies, mask/limit testing can be a valuable productivity tool (DSOX3MASK). The 3000T X-Series features powerful hardware-based mask testing that can perform up to 270,000 tests per second. You can select multiple test criteria, including the ability to run tests for a specific number of acquisitions, a specified time, or until detection of a failure.
Solve: Integrated power measurements and analysis (option) make short work of power measurements
When you are working with switching power supplies and power devices, the power measurements application (DSOX3PWR) provides a full suite of power measurements and analysis in the oscilloscope.
Included with the DSOX3PWR is a license for the U1881A PC-based power analysis software package, which provides additional offline measurements and report generation.
In addition there are several power specific probes that make analysis of your power supplies (e.g. switch mode power supplies) and power consuming devices (e.g. batteries) easy.
Solve: Innovative power rail probe (option) allows enhanced views.
The power rail noise, ripple, and transients measurements can be challenging due to required offset range and mV sensitivity. With its ±24 V offset range, ultra-low noise 1:1 attenuation ratio, and 2-GHz bandwidth, the N7020A power rail probe is for users making critical power integrity measurements that need mV sensitivity on their DC power rails.
Solve: Video analysis (option)
Whether you are debugging consumer electronics with HDTV or characterizing a design, the HDTV measurement application (DSOX3VID) provides support for a variety of HDTV standards for triggering and analysis.
While the “Touch, Discover, Solve” elements of the scope highlight the key features that will make it easy to debug and troubleshoot your device, there are other features that you may also want to consider when choosing your next oscilloscope.
