All-digital GHz scopes analyze a million wavesforms a second

All-digital GHz scopes analyze a million wavesforms a second

Designed for speed and signal fidelity as digital instruments from the ground up, RTO10XX series oscilloscopes can analyze one million waveforms per second, allowing even the least-frequent errors to be seen in an instant. Initially available in two- and four-channel models with 1- and 2-GHz bandwidths and a maximum sampling rate of 10 Gsample/s, the scopes are the first to feature a fully digital trigger system, thereby minimizing trigger jitter so that glitches as small as 100 ps can be reliably detected.

The scopes’ 1-Mwaveform/s acquisition rate is achieved using a custom ASIC to perform real-time digital processing of measurements at a rate significantly faster than conventional scopes. Even at this high acquisition rate, all setting options and analysis functions are available, which is not the case for competitive units.

Each channel’s 8-bit ADC operates at 10 Gsamples/s; interleaving, with the possibility of ADC mismatch is thus avoided, thereby providing more than seven effective bits for a very high dynamic range, minimal signal distortion, and low inherent noise.

Unlike conventional trigger systems that must deal with time and amplitude offset between the analog trigger path and the digital signal acquisition path, the RTO series provides a purely digital trigger architecture, with the trigger and the captured data sharing a common signal path and a common time base. In addition to providing exceptionally low trigger jitter and exact trigger-signal assignment, the digital trigger rearms immediately after a trigger event so that faults do not go undetected.

A completely rethought user interface featuring advanced 10.4-in.-touchscreen operation, semitransparent dialog boxes, movable measurement windows, configurable toolbar, and preview icons with live waveforms provides an highly effective waveform overview even for complex measurements. A range of advanced active and passive probes are offered to support the units. (1-GHz units, from about $21,000; 2-GHz units, from about $26,000 available 5 weeks ARO.)
