The Tektronix MSO2014 delivers advanced debug features at an entry-level price. With up to 20 channels for analyzing analog and digital signals, you can quickly find and diagnose problems in complex designs. To capture long windows of signal activity while maintaining fine timing resolution, the Tektronix MSO2014 offers a deep record length of 1 Mpoints standard on all channels.
With Wave Inspector® controls for rapid waveform navigation and automated serial and parallel bus analysis, the MSO2014 from Tektronix provides the feature-rich tools you need to simplify and speed debug of your complex design.
The Tektronix MSO/DPO2000 Series redefines expectations for working with long record lengths with the following innovative Wave Inspector controls:
A dedicated, two-tier front-panel control provides intuitive control of both zooming and panning. The inner control adjusts the zoom factor (or zoom scale); turning it clockwise activates zoom and goes to progressively higher zoom factors, while turning it counterclockwise results in lower zoom factors and eventually turning zoom off. The outer control pans the zoom box across the waveform to quickly get to the portion of the waveform you are interested in.
The outer control also utilizes force-feedback to determine how fast to pan on the waveform. The farther you turn the outer control, the faster the zoom box moves. Pan direction is changed by simply turning the control the other way. No longer do you need to navigate through multiple menus to adjust your zoom view.
A dedicated play/pause button on the front panel scrolls the waveform across the display automatically while you look for anomalies or an event of interest. Playback speed and direction are controlled using the intuitive pan control.
Once again, turning the control further makes the waveform scroll faster and changing direction is as simple as turning the control the other way.
See something interesting on your waveform? Press the Set Mark button on the front panel to leave one or more “bookmarks” on the waveform. Navigating between marks is as simple as pressing the Previous (←) and Next (→) buttons on the front panel.
Don’t want to take the time to inspect the entire acquisition manually to find the event you’re looking for? The MSO/DPO2000 Series features a robust automatic waveform search feature that allows you to search through your long acquisition based on user-defined criteria. All occurrences of the event are highlighted with search marks and are easily navigated to, using the front-panel Previous (←) and Next (→) buttons. Search types include edge, pulse width, runt, logic, setup and hold, rise/fall time and parallel, I2C, SPI, RS-232/422/485/ UART, CAN, and LIN packet content.
Serial Triggering and Analysis
One of the most common applications requiring long record length is serial data analysis in embedded system design.
Embedded systems are virtually everywhere. They can contain many different types of devices including microprocessors, microcontrollers, DSPs, RAM, EEPROMs, FPGAs, ADCs, DACs, and I/O. These various devices have traditionally communicated with each other and the outside world using wide parallel buses. Today, however, more and more embedded systems are replacing these wide parallel buses with serial buses due to lower board space requirements, fewer pins, lower power, embedded clocks, differential signaling for better noise immunity and most importantly, lower cost. In addition, there’s a large supply of off-the-shelf building block components from reputable manufacturers, enabling rapid design development.
While serial buses have a large number of benefits, they also present significant challenges that their predecessors (parallel buses) did not face. They make debugging bus and system problems more difficult, it’s harder to isolate events of interest and it’s more difficult to interpret what is displayed on the oscilloscope screen. The MSO2000 and DPO2000 Series address these challenges and represent the ultimate tool for engineers working with serial buses such as I2C, SPI, RS-232/422/ 485/UART, CAN, and LIN.
Provides a higher level, combined view of the individual signals (clock, data, chip enable, etc.) that make up your bus, making it easy to identify where packets begin and end and identifying sub-packet components such as address, data, identifier, CRC, etc.
Trigger on packet content such as start of packet, specific addresses, specific data content, unique identifiers, etc., on popular serial interfaces: I2C, SPI, RS-232/422/485/UART, CAN, and LIN.
Tired of having to visually inspect the waveform to count clocks and determine if each bit is a 1 or a 0, and then combine bits into bytes and determine the hex value? Let the oscilloscope do it for you! Once you’ve set up a bus, the oscilloscope will decode each packet on the bus and display the value in either hex, binary, decimal (LIN only), or ASCII (RS-232/422/485/UART only) in the bus waveform.
In addition to seeing decoded packet data on the bus waveform itself, you can view all captured packets in a tabular view much like you would see on a logic analyzer. Packets are time-stamped and listed consecutively with columns for each component (Address, Data, etc.). The event table can also be exported for use offline.
Serial triggering is very useful for isolating an event of interest, but once you’ve captured it and need to analyze the surrounding data, what do you do? In the past, you had to manually scroll through the waveform, counting and converting bits and looking for what caused the event. With the MSO2000 and DPO2000 Series, you can have the oscilloscope automatically search through the acquired data for user-defined criteria including serial packet content. Each occurrence is marked for easy reference.
Rapid navigation between marks is as simple as pressing the Previous (←) and Next (→) buttons on the front panel.
Mixed Signal Design and Analysis (MSO2000 Series)
As an embedded-design engineer, you are faced with the challenge of ever-increasing system complexity. A typical embedded design may incorporate various analog signals, high- and low-speed serial digital communication and microprocessor buses, just to name a few. Serial protocols such as I2C and SPI are used frequently for chip-to-chip communication, but parallel buses are still used in many applications.
Microprocessors, FPGAs, Analog-to-Digital Converters (ADCs), and Digital-to-Analog Converters (DACs) are all examples of ICs that present unique measurement challenges in today’s embedded designs. The MSO2000 Series Mixed Signal Oscilloscopes offer the addition of 16 digital channels. These channels are tightly integrated into the oscilloscope’s user interface, simplifying operation and making it possible to solve mixed signal issues easily.
Next Generation Digital Waveform Display
In a continued effort to make mixed signal oscilloscopes easy to use, the MSO2000 Series has redefined the way you view digital waveforms. One common problem shared by both logic analyzers and mixed signal oscilloscopes is determining if data is a one or a zero when zoomed in far enough that the digital trace stays flat all the way across the display. The MSO2000 has colorcoded the digital traces, displaying ones in green and zeros in blue. In addition, the MSO2000 displays white edges around the transition points of digital channels when there is uncertainty between sample points. This acts as a visual reminder that increasing the sample rate on the next acquisition will reveal higher frequency information than your previous settings could acquire.
Channel setup on an MSO can often be time consuming as compared to the traditional oscilloscope. This process often includes probing the device undertest, labeling the channels, and positioning the channels on screen. The MSO2000 simplifies this process by allowing the user to group digital waveforms and enter waveform labels using a USB keyboard. By simply placing digital waveforms next to each other, they form a group. Once a group is formed, you can position all the channels contained in that group together. This greatly reduces the normal setup time associated with positioning channels individually.
PC Connectivity and USB Data Storage
The MSO2000 and DPO2000 Series provides flexibility in data transfer with standard USB host and device ports which enable removable data storage, seamless PC connectivity, and direct printing. Also available are optional GPIB, LAN, and Video-Out adaptors.
Easily capture, save and analyze measurement results with OpenChoice® Desktop PC Communications software. Simply pull screen images and waveform data into the stand-alone desktop application or directly in Microsoft Word and Excel.
To complement OpenChoice, National Instruments LabVIEW SignalExpressTM Tektronix Edition software provides you with extended capabilities, including advanced analysis, remote oscilloscope control and live waveform analysis. Alternatively, if you prefer not to use the PC, you can simply print your image directly to any PictBridge® compatible printer using the USB device port.
The TekVPI probe interface sets the standard for ease of use in probing. TekVPI probes feature status indicators and controls, as well as a probe menu button right on the input compensation 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 utilizes a new probe power management architecture enabling direct attachment of current probes. (Requires TekVPI External Power Supply - Tektronix Part number: 119-7465-xx).
Finally, TekVPI probes can be controlled remotely by using USB, GPIB, or Ethernet, enabling more versatile solutions in ATE environments.
