RS 4GHz scope delivers an impressive 20 Gsample/s
Rohde and Schwarz  has launched a 4GHz oscilloscope with a 20 Gsample/s sampling rate. The company says it's ideal for analysing fast signals and steep edges, since it can handle different data interfaces up to a data rate of 1.6 Gbps and can also be used to test fast clock signals up to 800 MHz.
High sensitivity and measurement accuracy make the R&S RTO an indispensable tool for measurements of typically low-amplitude (< 1 V) signals. Thanks to the low-noise frontend, the full measurement bandwidth of 4 GHz is available at even the smallest scaling (1 mV/div). The 10 GHz single-core A/D converter provides an outstanding dynamic range (ENOB > 7 bit). Another unique characteristic is the unprecedented high acquisition and analysis rate of 1 million waveforms per second. The digital trigger system makes it possible to accurately pinpoint narrow glitches (down to 50 ps) and their origin. And an adjustable trigger hysteresis allows users to optimize the trigger sensitivity to the signal characteristics.
The combination of fast FFT analysis, high dynamic range and a bandwidth of up to 4 GHz makes the R&S RTO1044 ideal for frequency domain measurements. 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.
Rohde & Schwarz oscilloscopes feature touchscreen operation. The cleverly designed screen with its semi-transparent dialog boxes, drag-and-drop measurement windows, configurable toolbar and preview icons with live waveforms allows users to accomplish even complex measurement tasks quickly and efficiently. The 10.4 inch touchscreen strikes the right balance between usability and compactness.
