The introduction of using DPO/MSO2000B mixed signal oscilloscopes series part 1Follow article
We have introduced the features and technical data of DPO/MSO2000B mixed signal oscilloscopes series in the before knowledge item. The DPO/MSO2000B mixed signal oscilloscopes series have compact and beautiful appearance and easy to carry. Offering up to 200 MHz bandwidth and 1 GS/s sample rate, the DPO/MSO2000B Mixed Signal Oscilloscope Series provides advanced debug features at an entry-level price. With as many as 20 channels, you can analyze analog and digital signals with a single instrument. Combine that with automated serial and parallel bus analysis, FilterVu™ low-pass filter and innovative Wave Inspector® controls, and the MSO/DPO2000B Series provides the feature-rich tools you need to simplify and speed debug of your complex design. Today we will continue introduce how to use the DPO/MSO2000B mixed signal oscilloscopes series.
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.
How to use DPO/MSO2000B discover wrong signal quickly?
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.
Discover - A waveform capture rate of 5,000 wfm/s maximizes the probability of capturing elusive glitches and other infrequent events.
How to capture the signal which you care?
Wave Inspector controls provide unprecedented efficiency in viewing, navigating, and analyzing waveform data. Zip through your 1M point record by turning the outer pan control (1). Get from the beginning to end in seconds. See something of interest and want to see more details? Just turn the inner zoom control (2).
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.
Capture - Triggering on a specific transmit data packet going across an RS-232 bus. A complete set of triggers, including triggers for specific serial packet content, ensures you quickly capture your event of interest.
How to search the events which you care?
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. 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.
Search - I2C decode showing results from a Wave Inspector search for Address value 50. Wave Inspector controls provide unprecedented efficiency in viewing and navigating waveform data.
Search step 1: You define what you would like to find
Search step 2: Wave Inspector automatically searches through the record and marks each event with a hollow white triangle. You can then use the Previous and Next buttons to jump from one event to the next.
