Scope, spectrum-analyzer combination provides time-correlated signals
With the MDO4000, the RF-input frequency range extends to 6 GHz and provides a capture bandwidth of ≥1 GHz at all center frequencies, 100 times wider than that of typical spectrum analyzers. Users can see up to four decoded serial buses, parallel buses, or both at one time on the same display. The time correlation between domains enables accurate timing measurements for understanding delays and latencies between command and control events in a design and changes in the RF spectrum.
In addition to the standard RF power-level trigger, an optional module, MDO4TRIG, allows additional trigger types to use the RF power level as a source, enabling customers to further isolate an RF event of interest. Users can trigger on a specific pulse width, look for a time-out event or runt, or even include the RF input in a logic pattern defined along with the analog and digital channels.
“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,” says Roy Siegel, general manager, oscilloscopes, at Tektronix. “Just as the MSO [mixed-signal oscilloscope] is the standard for embedded-design test, we expect the MDO will become the new standard for designs that increasingly include RF capabilities.”
The MDO4000 enables debugging integration of common wireless modules below 6 GHz—WLAN, Bluetooth, and Zigbee, for example; debugging of common “homegrown” amplitude-, frequency-, or phase-modulated wireless communications; and wideband analysis of dual-band transceivers. US suggested list prices start at $19,900.
