Scope can cope with multi-domain applications

Embedded World Exhibition, Germany: Electronic design engineers must be able to perform complex measurement tasks quickly and accurately and making its debut at the show was Rohde & Schwarz' R&S RTO2000, a fast and compact lab oscilloscope for multi-domain applications.
The company says that when used to check advanced embedded designs, developers are able to analyse how power supplies, processors and the sensor technology interact with each other. The display shows the correlations between time, frequency, protocol and logic analysis measurement.
Via the analog input channels, a user simultaneously sees the signal in the time and frequency domain, and if needed, the spectrogram. Newly added functions include peak list, max. hold detectors and the logarithmic display.
Detecting disturbances in the spectrum
The new zone trigger enables the graphical separation of events in the time and frequency domain. Users can define up to eight zones of any shape. A trigger signal is activated when a signal either intersects or does not intersect the zone. What this means it is easier to detect disturbances in the spectrum during EMI debugging or to separate read/write cycles of storage media in the time domain.
Rohde & Schwarz believe this is the first oscilloscope in this class to offer a memory of up to 2 Gsample. This is useful for the history function which provides access to previously acquired waveforms. A trigger timestamp allows time correlation. Users can view all saved signals and analyse them with tools such as zoom, measurement, math and spectrum analysis functions. Signal processing in the ASIC and intelligent memory management ensure smooth handling of long pulse and protocol sequences.
High definition (HD) mode of this new scope increases the vertical resolution to up to 16bits, making signal details visible. The HD mode activates configurable low pass filtering of the signal after the A/D converter. Users can trigger on all, even the smallest, signal details.
With one million waveforms per second users are able to quickly detect sporadic signal faults.
