Six in one oscilloscope gets performance upgrade

Improved scope performance and a 6GHz spectrum analyser are the latest upgrades to the TektronixMDO4000C Series of Mixed Domain Oscilloscopes. The instruments can be configured with up to six instruments in a single unit including a full spectrum analyser.

Engineers can upgrade their MDO4000C instruments over time to meet demanding challenges and add functionality as needs change or budgets allow.

As with previous generations in the MDO4000 series, the MDO4000C provides a synchronised view of analogue and digital waveforms along with RF spectrum traces, making it a suitable debug tool for Internet of Things (IoT) and many other embedded engineering applications.

Like the 6-in-1 MDO3000 introduced last year, the MDO4000C expands on its core oscilloscope functionality with options to add a spectrum analyzer, arbitrary/function generator, logic analyaer and protocol analyser. A digital voltmeter (DVM) is available for free with product registration.

“Integrated instruments have proved highly popular with our customers because they can cover more debugging and analysis tasks with a single instrument, allowing them to keep engineering programs on track and get to market faster,” said Chris Witt, general manager, Mainstream Oscilloscopes, Tektronix. “The increased performance of the MDO4000C – what we call 6-in-1 plus – makes it the optimal tool for solving tough design problems.”

As an oscilloscope, the MDO4000C features long record length, fast sample rate and fast waveform capture rate to help uncover elusive problems.

Performance enhancements compared to the MDO3000 integrated oscilloscope include:

  • More scope performance – 20Mpoint record length, up to 5 GS on all channels, >340,000 waveforms/s capture rate and a 50% larger display
  • Up to 6GHz spectrum analyser with better spectrum analyser performance, the ability to synchronise views across time and frequency domains, and the ability to perform vector signal analysis
  • Logic analyser timing resolution down to 60.6ps and independent logic thresholds per channel enabling capture of multiple logic families at once
  • Protocol analysis for up to three buses simultaneously with triggering up to 500Mb/s

The instruments save bench space and improve usability and are easy to acquire and own. The MDO4000C can be configured as a base oscilloscope with an entry price of just €6,900.  A 3- or 6-GHz spectrum analyser, arbitrary/function generator, 16 logic channels, or protocol support can be added at the time of purchase, or added later as an upgrade, allowing it to precisely conform to every lab’s needs and budget. Oscilloscope bandwidth extends from 200MHz to 1GHz and can also be upgraded at any time.
