Comprehensive Features Speed Every Stage of Debug The MSO/DPO2000B Series offers a robust set of features to speed every stage of debugging your design – from quickly discovering an anomaly and capturing it, to searching your waveform record for the event and analyzing its characteristics and your device’s behavior. Discover 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 MSO/DPO2000B Series offers complete visualization of signals, providing fast insight into the real operation of your device. A waveform capture rate of 5,000 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. Capture Discovering a device fault is only the first step. Next, you must capture the event of interest to identify a root cause. The MSO/DPO2000B Series provides a complete set of triggers – including runt, logic, pulse width/glitch, setup/hold violation, serial packet, and parallel data – to help quickly find your event. 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. From triggering on specific packet content to automatic decode in multiple data formats, the MSO/DPO2000B Series provides integrated support for a broad range of serial buses – I2C, SPI, CAN, LIN, and RS-232/422/485/UART. The ability to decode up to two serial and/or parallel buses simultaneously means you gain insight into system-level problems quickly. To further help troubleshoot system-level interactions in complex embedded systems, the MSO2000B Series offers 16 digital channels in addition to its analog channels. Since the digital channels are fully integrated into the oscilloscope, you can trigger across all input channels, automatically time-correlating all analog, digital, and serial signals. 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 pushing to a million data points, locating your event can mean scrolling through thousands of screens of signal activity. The MSO/DPO2000B Series offers the industry’s most comprehensive search and waveform navigation with its 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. User marks allow you to mark any location that you may want to reference later for further investigation. Or, automatically search your record for criteria 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. Analyze 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 MSO/DPO2000B Series 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. Wave Inspector® Navigation and Search A 1 Mpoint record length represents thousands of screens of information. The MSO/DPO2000B Series enables you to find your event in seconds with Wave Inspector, the industry’s best tool for navigation and search. Wave Inspector offers the following innovative controls: Zoom/Pan 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. Play/Pause A dedicated Play/Pause front-panel button 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. User Marks Press the Set Mark front-panel button to place one or more marks on the waveform. Navigating between marks is as simple as pressing the Previous (←) and Next (→) buttons on the front panel. Search Marks The Search button 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 front-panel Previous (←) and Next (→) buttons. Search types include edge, pulse width/glitch, runt, logic, setup and hold, rise/fall time parallel bus, and I2C, SPI, CAN, LIN, and RS-232/422/485/UART packet content. Digital Phosphor Technology The MSO/DPO2000B Series’ digital phosphor technology provides you with fast insight into the real operation of your device. Its waveform capture rate of 5,000 wfm/s gives you a high probability of quickly seeing the infrequent problems common in digital systems: runt pulses, glitches, timing issues, and more. Waveforms are superimposed with one another and waveform points that occur more frequently are intensified. This quickly highlights the events With the color-coded digital waveform display, groups are created by simply placing digital channels together on the screen, allowing the digital channels to be moved as a group. You can set threshold values for each pod of eight channels, enabling support for up to two different logic families. that over time occur more often or, in the case of infrequent anomalies, occur less often. With the MSO/DPO2000B Series, 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. FilterVu™ Variable Low-pass Filter 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. When the noise filter is adjusted to the lowest available noise-cutoff frequency, no more than 1% of high-frequency content that could cause the oscilloscope to alias will pass through the filter. The glitch capture waveform shows signal details up to the full bandwidth of the oscilloscope. The oscilloscope captures pulses as narrow as 5 ns, using peak-detect min/max sampling, protecting you from missing unexpected glitches or other high-frequency events. FilterVu is ideal for repetitive, nonrepetitive, and single-shot events. Serial Triggering and Analysis (Optional) On a serial bus, a single signal often includes address, control, data, and clock information. This can make isolating events of interest difficult. The MSO/DPO2000B Series offers a robust set of tools for debugging serial buses with automatic trigger, decode, and search for I2C, SPI, CAN, LIN, and RS-232/422/485/UART. Serial Triggering Trigger on packet content such as start of packet, specific addresses, specific data content, unique identifiers, etc. on popular serial interfaces such as I2C, SPI, CAN, LIN, and RS-232/422/485/UART. Bus Display 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 subpacket components such as address, data, identifier, CRC, etc. Bus Decoding 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! Once you’ve set up Event table showing decoded Identifier, DLC, DATA, and CRC for every CAN packet in a long acquisition. a bus, the MSO/DPO2000B Series will decode each packet on the bus, and display the value in hex, binary, decimal (LIN only), or ASCII (RS-232/422/485/UART only) in the bus waveform. Event Table 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.). Search 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 MSO/DPO2000B Series, 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. Rapid navigation between marks is as simple as pressing the Previous (←) and Next (→) buttons on the front panel. Designed to Make Your Work Easier Bright, Widescreen Display The MSO/DPO2000B Series features a 7 inch (180 mm) widescreen, TFT-LCD display for seeing intricate signal details. Dedicated Front-panel Controls 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. Connectivity A USB host port on the front panel enables easy transfer of screenshots, instrument settings, and waveform data to a USB thumb drive. The rear panel contains a USB device port for controlling the oscilloscope remotely from a PC or for connecting a USB keyboard.
