MANHASSET, NY -- Tektronix, Inc. has introduced a mixed-domain oscilloscope that delivers the functionality of an scope and a spectrum analyzer in a single instrument. And Rohde & Schwarz has enhanced its real-time digital trigger scope for analyzing extremely small signals with high fidelity. Both companies will exhibit their wares at the Embedded Systems Conference, Boston (Sept. 26 to 29)
Tek’s MDO4000 Series enables time-correlated analog, digital and rf signals to be captured in a complete system view.
“We believe that the MDO4000 Series is breaking down the barrier between time and frequency domains,” said Roy Siegel, general manager, Oscilloscopes at Tektronix. “It fundamentally changes what’s involved in debugging designs with rf where there is a need to correlate events in the frequency domain with the time domain phenomena that caused them.”
The MDO4000 allows users to capture time-correlated analog, digital and rf signals across 4 analog, 16 digital and 1 rf channel. The rf input frequency range extends up to 6 GHz and provides a capture bandwidth of 1 GHz at all center frequencies, 100 times wider than typical spectrum analyzers, according to Tektronix.
Time correlation measurements between domains enables engineers to understand delays and latencies between command/control events in their designs and the relative changes in the rf spectrum of a signal at any point in time within a long acquisition. A proprietary Spectrum Time function enables the view of the rf spectrum for any point in the acquired signal while simultaneously showing analog, digital and/or decoded buses.
Tektronix has 26 patents pending for integrating the time and frequency domains in a single instrument. The MDO4000 Series start at $19,900.

Meanwhile the Rohde & Schwarz RTO Scope Series enables signals to be displayed with the least possible trigger jitter. The company is aiming the digital scope for debugging biomedical sensors and equipment.
“The RTO oscilloscope family is well-suited for biomedical measurements based on its low noise front-end performance and a/d converter to deliver accurate signal acquisition,” said Mike Schnecker, business development manger at Rohde & Schwarz.
The digital trigger in the RTO Scope Series does not need to “re-arm” as in analog triggers, allowing every sample to trigger data acquisition and thus avoid missing events.
Models in the RTO Scope Series allow between 2 or 4 channels, and 1 GHz or 2 GHz bandwidths. Sampling rates are up to 10 Gsample/s, enabled by the company-designed and-built high-speed ASIC, deep waveform acquisition memory and the single-core A/D converter, according to R&S. The low-noise front end makes precise measurements possible even at the lowest vertical setting, according to Schnecker.
One "cool factor" in the RTO series is that engineers can drag & drop signal icons anywhere on the 10.4-in touch display to keep track of channels, math waveforms and reference signals--all on a single screen.
Signal icons show waveforms in real time as thumbnails that can be dragged and dropped to the main display as needed. Users can activate multiple diagrams and a SmartGrid function helps in organizing the screen. Semi-transparent dialog boxes allow waveform diagrams on the RTO retain their original size. Semi-transparent overlays map processed signals onto a signal flow diagram, for example.
ESC Boston attendees will be able to win scopes in the giveaway session
