Rohde & Schwarz 2 GHz scope offers linked multi-domain views

February 24, 2016 // By Graham Prophet
Rohde & Schwarz' RTO2000, is a compact lab oscilloscope for multi-domain applications, displaying correlations between time, frequency, protocol and logic analysis measurement results.

Via the analogue input channels, the user simultaneously sees the signal in the time and frequency domain, and if desired, the spectrogram. Newly added functions such as peak list, max. hold detectors and the logarithmic display make frequency analysis even more efficient.

A 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. This makes it easy to detect disturbances in the spectrum during EMI debugging or to separate read/write cycles of storage media in the time domain.

It 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 at any time. 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.

A high definition (HD) mode increases the vertical resolution to up to 16 bits, making signal details visible. Achieved by signal processing, the high-resolution mode trades bandwidth for increased detail. The HD mode activates configurable lowpass filtering of the signal after the A/D converter.

With one million waveforms per second, the R&S RTO2000 sets a new standard in this class of oscilloscopes. Users are able to quickly detect sporadic signal faults. The scope provides high-speed analysis even when histogram and mask functions are active. With a 12.1-in. capacitive touchscreen with gesture support and colour-coded controls, users can configure the instrument for any measurement task. Users can customise the waveform display with SmartGrid. They can quickly access important tools on a toolbar and document measurement results and instrument settings at the press of a
