To debug a design problem, first you must know it exists. Every design engineer spends time looking for problems in their design, a time-consuming and frustrating task without the right debug tools. The DPOB offers complete visualization of signals, providing fast insight into the real operation of your device. A waveform capture rate of 5, waveforms per second enables you to see glitches and other infrequent transients quickly, revealing the true nature of device faults.
A digital phosphor display with intensity grading shows the history of a signal's activity by intensifying areas of the signal that occur more frequently, providing a visual display of just how often anomalies occur. Discovering a device fault is only the first step. Next, you must capture the event of interest to identify root cause.
With up to a 1 Mpoint record length, you can capture many events of interest, even thousands of serial packets, in a single acquisition for further analysis while maintaining high resolution to zoom in on fine signal details. Finding your event of interest in a long waveform record can be time consuming without the right search tools.
With today's record lengths pushing to a million data points, locating your event can mean scrolling through thousands of screens of signal activity. The DPOB offers the industry's most comprehensive search and waveform navigation with its innovative Wave Inspector controls. These controls speed up panning and zooming through your record.
A unique force-feedback system lets you move from one end of your record to the other in just seconds. You can mark any location you may want to reference later for further investigation, and automatically search the record using criteria that you define. Wave Inspector will instantly search your entire record, including analog, digital, and serial bus data. Along the way, it will automatically mark every occurrence of your defined event so you can quickly move between events.
Verifying that your prototype's performance matches simulations and meets the project's design goals requires analyzing its behavior. Tasks can range from simple checks of rise times and pulse widths to sophisticated power loss analysis and investigation of noise sources.
The DPOB offers a comprehensive set of integrated analysis tools including waveform and screen-based cursors, 29 automated measurements, and FFT analysis. Specialized application support for serial bus analysis is also available. A 1M point record length represents thousands of screens of information. The DPOB enables you to search through it all and find your event in seconds with Wave Inspector, the industry's best tool for navigation and search.
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. No longer do you need to navigate through multiple menus to adjust your zoom view. The outer control pans the zoom box across the waveform to quickly get to the portion of 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. 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.
Press the Set Mark front-panel button to place one or more marks on the waveform. The Search button allows you to automatically search through your long acquisition looking for user-defined events. The DPOB's digital phosphor technology provides you with fast insight into the real operation of your device. Waveforms are superimposed with one another and waveform points that occur more frequently are intensified. This quickly highlights the events that over time occur more often or, in the case of infrequent anomalies, occur less often.
With the DPOB, you can choose infinite persistence or variable persistence, determining how long the previous waveform acquisitions stay on-screen. This allows you to determine how often an anomaly is occurring.
The multiple transition detection hardware of the DPOB will show you a white edge on the display when the system detects multiple transitions. 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. 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 collectively.
This greatly reduces the normal setup time associated with positioning channels individually. Tired of being limited to a 20 MHz bandwidth filter in your oscilloscope? Simply turn on FilterVu and adjust the variable low-pass noise filter. Unlike other variable low-pass filters, FilterVu filters out the unwanted noise from your signal while still capturing glitches and other signal details up to the full bandwidth of the oscilloscope.
It does this by showing two waveforms: a waveform that can be filtered foreground waveform and a glitch capture waveform background waveform.
The filtered waveform uses a variable low-pass filter to block out noise, yielding a cleaner waveform to more precisely locate signal edges and amplitude levels. The result is improved confidence in you cursor measurements and cleaner documentation of important signal attributes. The glitch capture waveform shows signal details up to the full bandwidth of the oscilloscope. FilterVu is ideal for repetitive, nonrepetitive, and single-shot events. On a serial bus, a single signal often includes address, control, data, and clock information.
This can make isolating events of interest difficult. Automatic trigger, decode, and search on bus events and conditions gives you a robust set of tools for debugging serial buses. The optional serial protocol triggering and analysis functionality is offered free for a day trial period.
This free trial period starts automatically when the instrument is powered on for the first time. Trigger on packet content such as start of packet, specific addresses, specific data content, unique identifiers, etc. Provides a higher-level, combined view of the individual signals clock, data, chip enable, etc. Tired of having to visually inspect the waveform to count clocks, determine if each bit is a 1 or a 0, combine bits into bytes, and determine the hex value?
Let the oscilloscope do it for you! 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 in a software listing. Packets are time stamped and listed consecutively with columns for each component Address, Data, etc. Serial triggering is very useful for isolating the event of interest, but once you've captured it and need to analyze the surrounding data, what do you do?
In the past, users had to manually scroll through the waveform counting and converting bits and looking for what caused the event.
With the DPOB, you can have the oscilloscope automatically search through the acquired data for user-defined criteria including serial packet content. Each occurrence is highlighted by a search mark. The DPOB is designed to make your work easier. The bright, widescreen display shows a long time window. Dedicated front-panel controls simplify operation. A USB host port on the front panel allows you to easily transfer screenshots, instrument settings, and waveform data to a USB flash drive.
Per-channel vertical controls provide simple and intuitive operation. No longer do you need to share one set of vertical controls across all four channels.
A USB host port on the front panel enables easy transfer of screenshots, instrument settings, and waveform data to a USB thumb drive. A compact, portable form factor allows the DPOB to be easily moved between labs and, with a depth of just 5.
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 comp box itself. This button brings up a probe menu on the oscilloscope display with all relevant settings and controls for the probe. Key software applications - OpenChoice Desktop, and Microsoft Excel and Word toolbars - are included standard with each oscilloscope to enable fast and easy direct communication with your Windows PC.
