Rohde & Schwarz has announced a 4GHz oscilloscope that it claims delivers the highest precision and acquisition rate in its class.

The RTO1044 oscilloscope features a 20Gs/s sampling rate and is designed to address applications such as analysis of fast signals and steep edges, handling different data interfaces up to a data rate of 1.6Gb/s and testing fast clock signals up to a frequency of 800MHz. According to R&S, the RTO series incorporates high sensitivity and measurement accuracy and is suitable for measurements of typically low amplitude (<1V) signals. The scopes incorporate low noise frontend and the full measurement bandwidth of 4GHz is available at scaling of 1 mV/div. The 10GHz single core a/d converter is designed to provide a dynamic range of ENOB >7bit. Another unique characteristic is the unprecedented high acquisition and analysis rate of 1million waveforms per second. The digital trigger system makes it possible to accurately pinpoint narrow glitches (down to 50ps) and their origin, while an adjustable trigger hysteresis allows users to optimise the trigger sensitivity to the signal characteristics. A combination of fast FFT analysis, high dynamic range and a bandwidth of up to 4GHz makes the R&S RTO1044 suitable for frequency domain measurements. According to R&S, when verifying circuit designs and during debugging, even sporadic emi interferers are reliably detected. The spectra of up to four rf signals can be observed in parallel and phase coherent. The oscilloscopes have a 10.4in touchscreen incorporating semitransparent dialogue boxes, drag and drop measurement windows, configurable toolbar and preview icons with live waveforms. "The many features offered by the new 4GHz oscilloscope make it the ideal solution for general research, medical technology and the development of RF chipsets," said Jörg Fries, director of the Oscilloscope Subdivision at Rohde & Schwarz.
