Multifunction scope provides sync’d multi-domain signal views

December 09, 2015 // By Graham Prophet
Tektronix’ MDO4000C Series of Mixed Domain Oscilloscopes can be configured with up to six instruments in a single unit including a full spectrum analyser. Starting with the highest-performance oscilloscope of any 6-in-1 instrument from Tektronix, engineers can upgrade their MDO4000C instruments over time.

The MDO4000C provides a synchronised view of analogue and digital waveforms along with RF spectrum traces, for use as a debug tool for Internet of Things (IoT) and other embedded engineering applications. Like the 6-in-1 MDO3000, the MDO4000C expands on its core oscilloscope functionality with options to add a spectrum analyser, arbitrary/function generator, logic analyser and protocol analyser. A digital voltmeter (DVM) is free with product registration.

"Integrated instruments have proven 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 – 20 Mpoint record length, up to 5 Gsample/sec on all channels, >340,000 waveforms/sec capture rate and a 50% larger display

Up to 6 GHz 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 60.6 psec 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 500 Mb/sec

The MDO4000C can be configured as a base oscilloscope with an entry price of $7,300. 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 200 MHz to 1 GHz and can also be
