SmartGrid technology allows users to drag and drop signals on the screen as desired (Figure 1). Frequently used measurement functions and configurations can be pinned

to a toolbar at the top of the touchscreen. Acting as a main menu, the app cockpit provides a one-tap location to access all of the available oscilloscope applications. Even with the oscilloscope’s user menu opened, the user can see nearly all of the recently displayed waveforms (Figure 2). A low-noise front-end and a low-distortion A/D converter specially
developed for the oscilloscope form the basis for an accurate analysis of signal details. Additionally, with the HD mode digital filter, the oscilloscope achieves a maximum vertical resolution of 16-bit and a lower noise floor, allowing very small signals to be displayed with high resolution. Signal integrity of oscilloscope is clearly demonstrated by the spurious-free
dynamic range (SFDR) of 68 dB and the overall effective number of bits (ENOB) of 9.4. The patented digital trigger with adjustable hysteresis allows the high-resolution measurement of signals to be fully utilised. Signal processing in the oscilloscope is optimised by an ASIC. This allows
the oscilloscope to achieve an unmatched real-time acquisition rate of one million waveforms per second, enabling users to detect even sporadic signal anomalies. Rohde & Schwarz has additionally integrated a highly responsive
any improvements in the RTO6 Series from Rohde & Schwarz arose from customer suggestions to make their work easier with the oscilloscope. For a start, the large 15.6-inch high definition (HD) touchscreen and the new graphical user interface maximise the display area for measurement signals. Next, the

acquisition memory as standard in the new oscilloscope with a memory depth of 200 million measurement points (200 Mpoints) per channel, expandable to 2 Gpoints. A frequency stable oven-controlled crystal oscillator (OCXO) serving as an accurate clock source is included in the scope of delivery, giving the oscilloscope a very precise timebase. The zone trigger function, also included as standard in the oscilloscope, is
unique in the market. It allows the user to draw up to eight zones on the touchscreen and link them to logic functions that trigger the instrument (Figure 3). These fully independent zones can be located in the time domain of the measured waveforms or in their frequency domain, which means in the calculated spectrum (FFT). In addition, mask testing detects signal faults in the defined tolerance limits. The high acquisition rate of the oscilloscope is also especially helpful, for example, for performing eye diagram tests with good measurement statistics in a short time.

The oscilloscope comes with a new operating concept, a larger display and a comprehensive range of software options, providing fast, detailed insights into electronic designs. Optional functions for special applications can be activated by user-entered keycodes. That makes the oscilloscope suitable for a wide variety of applications, including automotive, communications, power electronics and EMI debugging as well as testing digital bus and interface standards.
