The Tektronix MSO54GSA5BW350 350 MHz, 4-FlexChannel, 6.25 GS/s Mixed Signal Oscilloscope, 62.5 Mpoints Record Length offers better visibility into complex systems with a large 15.6 in. high definition (1,920 x 1,080) display and many applications -- embedded systems, three-phase power electronics, automotive electronics, power supply design, and DC-to-DC power converters -- that require the observation of more than four analog signals to verify and characterize device performance, and to debug challenging system issues.

Three-Phase Input Voltages

Most engineers can recall situations in which they were debugging a particularly difficult problem and wanted greater system visibility and context, but the scope they were using was limited to two or four analog channels. Using a second scope involves significant effort to align trigger points, difficulty in determining timing relationships across the two displays, and documentation challenges.

FlexChannel Technology

FlexChannel Technology Enables Maximum Flexibility and Broader System Visibility

The Tektronix MSO54 5-BW-350 re-defines what a Mixed Signal Oscilloscope (MSO) should be. FlexChannel technology enables each of the inputs on the instrument to be used as a single analog channel or eight digital channels. The conversion is done by simply attaching a optional TLP058 logic probe to any input -- imagine the flexibility and configurability this feature provides. You can change the configuration at any time by simply adding or removing TLP058 logic probes, so you always have the right number of digital channels.

The Tektronix MSO54 5-BW-350 offers a new level of integration of digital channels. Digital channels share the same high sample rate (up to 6.25 GS/s) for fine timing resolution, and a long record length for long time captures as analog channels. Previous-generation MSOs required tradeoffs, with digital channels having lower sample rates or shorter record lengths than analog channels.

Green and Blue Color Coding

Color-coded digital traces make it easy to determine if a logic signal is a one or a zero, even when the trace is flat across the display. Ones are displayed in green and zeros in blue. Unique multiple-transition detection hardware indicates when more than one transition occurs within a sample interval. A white bar on the trace indicates that more information is available by zooming in or acquiring at faster sampling rates. Often, zooming in will reveal a glitch that was previously hidden. Distinct thresholds can be defined for each digital channel, enabling you to easily observe different logic families, unlike other MSOs that have one or two shared thresholds across all digital channels.

Unprecedented Signal Viewing Capability

The stunning 15.6 in. (396 mm) display in the MSO54 5-BW-350 provides 100% more display area than a scope with a 10.4 in. (264 mm) display. It is also has full HD resolution (1,920 x 1,080), enabling you to see many signals at once with ample room for critical readouts and analysis.

The viewing area is optimized to ensure that the maximum vertical space is available for waveforms. The Results Bar on the right can be hidden, enabling the waveform view to use the full width of the display.

The Tektrix MSO54 5-BW-350 offers a revolutionary new Stacked display mode. Historically, scopes have overlaid all waveforms in the same graticule, forcing difficult tradeoffs:

Stacked Display Mode

The new Stacked display eliminates this tradeoff. It automatically adds and removes additional horizontal waveform 'slices' (additional graticules) as waveforms are created and removed. Each slice represents the full ADC range for the waveform. All waveforms are visually separated from each other while still using the full ADC range, enabling maximum visibility and accuracy. And it is all done automatically as waveforms are added or removed! Channels can easily be reordered in stacked display mode by dragging and dropping the channel and waveform badges in the Settings bar at the bottom of the display.

The massive display in the Tektronix MSO54 5-BW-350 also provides plenty of viewing area not only for signals, but also for plots, measurement results tables, bus decode tables and more. You can easily resize and relocate the various views to suit your application.

Exceptionally Easy-to-Use User Interface Lets You focus on the Task at Hand

User Interface

The Settings Bar - key parameters and waveform management

Waveform and scope operating parameters are displayed in a series of "badges" in the Settings Bar that runs along the bottom of the display. The Settings Bar provides Immediate access for the most common waveform management tasks. With a single tap, you can:

Trigger Configuration Menu

The Results Bar - analysis and measurements

The Results Bar on the right side of the display includes immediate, onetap access to the most common analytical tools such as cursors, measurements, searches, measurement and bus decode results tables, plots, and notes.

DVM, measurement and search results badges are displayed in the Results Bar without sacrificing any waveform viewing area. For additional waveform viewing area, the Results Bar can be dismissed and brought back at any time.

Touch Interaction Finally Done Right

Scopes have included touch screens for years, but the touch screen has been an afterthought. The MSO54 5-BW-350's 15.6 in. display includes a capacitive touchscreen and provides the industry's first oscilloscope user interface truly designed for touch.

The touch interactions that you use with phones and tablets, and expect in a touch enabled device, are supported in the MSO54 5-BW-350.

Touch Display

Front Panel

Smooth, responsive front panel controls allow you to make adjustments with familiar knobs and buttons, and you can add a mouse or keyboard as a third interaction method.

Attention to Detail in the Front-Panel Controls

Traditionally, the front face of a scope has been roughly 50% display and 50% front panel. The Tektronix MSO54 5-BW-350 display fills about 85% of the face of the instrument. To achieve this, it has a streamlined front panel that retains critical controls for simple intuitive operation, but with a reduced number of menu buttons for functions directly accessed via objects on the display.

Color-coded LED light rings indicate trigger source and vertical scale/position knob assignments. Large, dedicated Run/Stop and Single Sequence buttons are placed prominently in the upper right, and other functions like Force Trigger, Trigger Slope, Trigger Mode, Default Setup, Autoset and Quick-save functions are all available using dedicated front panel buttons.

Windows or Not - You Choose

The Tektronix MSO54 5-BW-350 is the first oscilloscope to offer you the choice of whether to include a Microsoft Windows operating system. Opening an access panel on the bottom of the instrument reveals a connection for a solid state drive (SSD). When the SSD is not present, the instrument boots as a dedicated scope with no ability to run or install other programs.

When the SSD is present, the instrument boots in an open Windows 10 configuration, so you can minimize the oscilloscope application and access a Windows desktop where you can install and run additional applications on the oscilloscope. Or you can connect additional monitors and extend your desktop.

Whether you run Windows or not, the oscilloscope operates in exactly the same way with the same look and feel and UI interaction.

Experience the Performance Difference

With Tektronix MSO54 5-BW-350 analog bandwidth, 6.25 GS/s sample rates, standard 62.5 M record length and a 12-bit analog to digital converter (ADC), the MSO54 5-BW-350 has the performance you need to capture waveforms with the best possible signal fidelity and resolution for seeing small waveform details.

FastAcq Highspeed Waveform Capture

Digital Phosphor Technology with FastAcq Highspeed Waveform Capture

To debug a design problem, first you must know it exists. Digital phosphor technology with FastAcq provides you with fast insight into the real operation of your device. Its fast waveform capture rate - greater than 500,000 waveforms per second - gives you a high probability of seeing the infrequent problems common in digital systems: runt pulses, glitches, timing issues, and more. To further enhance the visibility of rarely occurring events, intensity grading indicates how often rare transients are occurring relative to normal signal characteristics.

Industry Leading Vertical Resolution

The Tektronix MSO54 5-BW-350 provides the performance to capture the signals of interest while minimizing the effects of unwanted noise when you need to capture high-amplitude signals while seeing smaller signal details. At the heart of the MSO54 5-BW-350 are 12-bit analog-to-digital converters (ADCs) that provide 16 times the vertical resolution of traditional 8-bit ADCs.

High Res Mode

A new High Res mode applies a hardware-based unique Finite Impulse Response (FIR) filter based on the selected sample rate. The FIR filter maintains the maximum bandwidth possible for that sample rate while preventing aliasing and removing noise from the oscilloscope amplifiers and ADC above the usable bandwidth for the selected sample rate. High Res mode always provides at least 12 bits of vertical resolution and extends all the way to 16 bits of vertical resolution at ≤125 MS/s sample rates.

New lower-noise front end amplifiers further improve the MSO54 5-BW-350's ability to resolve fine signal detail.

Triggering

Discovering a device fault is only the first step. Next, you must capture the event of interest to identify root cause. The Tektronix MSO54 5-BW-350 provides a complete set of advanced triggers, including:

Trigger Menu

With up to a 125 Mpoint optional record length, you can capture many events of interest, even thousands of serial packets in a single acquisition, providing high-resolution to zoom in on fine signal details and record reliable measurements.

Visual Trigger - finding the signal of interest quickly

Finding the right cycle of a complex bus can require hours of collecting and sorting through thousands of acquisitions for an event of interest. Defining a trigger that isolates the desired event speeds up debug and analysis efforts.

Isolate Events of Interest

Visual Trigger extends the MSO54 5-BW-350's triggering capabilities by scanning through all waveform acquisitions and comparing them to onscreen areas (geometric shapes). You can create an unlimited number of areas using the mouse or touchscreen, and a variety of shapes (triangles, rectangles, hexagons, or trapezoids) can be used to specify the desired trigger behavior. Once shapes are created, they can be edited interactively to create custom shapes and ideal trigger conditions. Once multiple areas are defined, a Boolean logic equation can be used to set complex trigger conditions using on-screen editing features.

Multiple Channel Triggering

By triggering only on the most important signal events, Visual Trigger can save hours of capturing and manually searching through acquisitions. In seconds or minutes, you can find the critical events and complete your debug and analysis efforts. Visual Trigger even works across multiple channels, extending its usefulness to complex system troubleshooting and debug tasks.

Accurate High-Speed Probing

The TPP Series passive voltage probes included with the Tektronix MSO54 5-BW-350 offer all the benefits of general-purpose probes -- high dynamic range, flexible connection options, and robust mechanical design, while providing the performance of active probes.

An optional, low-attenuation (2X) version of the TPP probe is available for measuring low voltages. Unlike other low-attenuation passive probes, the TPP0502 has high bandwidth (500 MHz) as well as low capacitive loading (12.7 pF).

TekVPI Probe Interface

The TekVPI probe interface sets the standard for ease of use in probing. In addition to the secure, reliable connection that the interface provides, many TekVPI probes feature status indicators and controls, as well as a probe menu button right on the comp box itself. This button brings up a probe menu on the oscilloscope display with all relevant settings and controls for the probe. The TekVPI interface enables direct attachment of current probes without requiring a separate power supply. TekVPI probes can be controlled remotely through USB or LAN, enabling more versatile solutions in ATE environments. The Tektronix MSO54 5-BW-350 provides up to 80 W of power to the front panel connectors, sufficient to power all connected TekVPI probes without the need for an additional probe power supply.

IsoVu Isolated Measurement System

Whether designing an inverter, optimizing a power supply, testing communication links, measuring across a current shunt resistor, debugging EMI or ESD issues, or trying to eliminate ground loops in your test setup, common mode interference has caused engineers to design, debug, evaluate, and optimize "blind" until now.

Tektronix' revolutionary IsoVu technology uses optical communications and power-over-fiber for complete galvanic isolation. When combined with the MSO54 5-BW-350 equipped with the TekVPI interface, it is the first, and only, measurement system capable of accurately resolving high bandwidth, differential signals, in the presence of large common mode voltage with:

Comprehensive Analysis for Fast Insight

Basic Waveform Analysis

Automated Measurements

Verifying that your prototype's performance matches simulations and meets the project's design goals requires careful analysis, ranging from simple checks of rise times and pulse widths to sophisticated power loss analysis, characterization of system clocks, and investigation of noise sources.

The Tektronix MSO54 5-BW-350 offers a comprehensive set of standard analysis tools including:

Measurement results tables provide comprehensive statistical views of measurement results with statistics across both the current acquisition and all acquisitions.

Navigation and Search

Finding your event of interest in a long waveform record can be time consuming without the right search tools. With today's record lengths of many millions of data points, locating your event can mean scrolling through literally thousands of screens of signal activity.

The Tektronix MSO54 5-BW-350 offers a comprehensive search and waveform navigation with innovative Wave Inspector controls. These controls speed panning and zooming through your record. With a unique force-feedback system, you can move from one end of your record to the other in just seconds. Or, use intuitive drag and pinch/expand gestures on the display itself to investigate areas of interest in a long record.

Search Feature

The Search feature allows you to automatically search through your long acquisition looking for user-defined events. All occurrences of the event are highlighted with search marks and are easily navigated to, using the Previous and Next buttons found on the front panel or on the Search badge on the display. Search types include edge, pulse width, timeout, runt, window, logic, setup and hold, rise/fall time and parallel/serial bus packet content. You can define as many unique searches as you like.

You can also quickly jump to the minimum and maximum value of search results by using the Min and Max buttons on the Search badge.

Serial Protocol Triggering and Analysis (Optional)

During debugging, it can be invaluable to trace the flow of activity through a system by observing the traffic on one or more serial buses. It could take many minutes to manually decode a single serial packet, much less the thousands of packets that may be present in a long acquisition.

Triggering on a USB

And if you know the event of interest that you are attempting to capture occurs when a particular command is sent across a serial bus, wouldn't it be nice if you could trigger on that event? Unfortunately, it's not as easy as simply specifying an edge or a pulse width trigger.

The Tektronix MSO54 5-BW-350 offers a robust set of tools for working with the most common serial buses found in embedded design including I2C, SPI, RS-232/422/485/UART, SPMI, CAN, CAN FD, LIN, FlexRay, SENT, USB LS/FS/HS, Ethernet 10/100, Audio (I2S/LJ/RJ/TDM), MIL-STD-1553, and ARINC 429.

Serial protocol search enables you to search through a long acquisition of serial packets and find the ones that contain the specific packet content you specify. Each occurrence is highlighted by a search mark. Rapid navigation between marks is as simple as pressing the Previous and Next buttons on the front panel or in the Search badge that appears in the Results Bar.

Compliance Applications (Optional)

A key focus area for embedded designers is testing various embedded and interface technologies for compliance. This ensures the device passes the logo certification at plugfests and achieves successful interoperability when working with other compliant devices.

TekExpress USB 2.0

The compliance test specifications for high speed serial standards like USB, Ethernet, Memory, Display and MIPI are developed by the respective consortiums or governing bodies. Working closely with these consortiums, Tektronix has developed oscilloscope-based compliance applications that not only focus on providing pass/fail results but also provide deeper insight into any failures by providing relevant measurement tools such as jitter and timing analysis to debug failing designs.

These automated compliance applications are built on a framework that provides:

Jitter Analysis

The Tektronix MSO54 5-BW-350 has seamlessly integrated the DPOJET Essentials jitter and eye pattern analysis software package, extending the oscilloscope's capabilities to take measurements over contiguous clock and data cycles in a single-shot real-time acquisition. This enables measurement of key jitter and timing analysis parameters such as Time Interval Error and Phase Noise to help characterize possible system timing issues.

Analysis tools, such as plots for time trends and histograms, quickly show how timing parameters change over time, and spectrum analysis quickly shows the precise frequency and amplitude of jitter and modulation sources.
