F ind signal faults fast Conventional digital oscilloscopes: long blind time with serious consequences The R&S®RTO oscilloscopes continuously capture and analyze waveforms up to one million times per second. This capability is unique among digital oscilloscopes and helps to find rare signal faults quickly. A digital oscilloscope acquires signals in two steps. First, it samples the measurement signal for a defined period of time and stores the samples. In a second step, it processes these samples and displays the waveform. During this period, the oscilloscope is “blind” to the measurement...

One million waveforms per second: ault finding f instead of guesswork Compared to conventional oscilloscopes, the blind time of the R&S®RTO oscilloscopes is up to twenty times shorter. This is due to the core component of the instrument – an ASIC designed specifically for intensive parallel processing. The ASIC processes the input signal within an extremely short period of time and prepares it for fast display on the screen. For this reason, the R&S®RTO oscilloscopes can acquire, analyze and display up to one million waveforms per second. Due to this high acquisition rate, the instruments...

Hardware- accelerated analysis An ASIC in the R&S®RTO oscilloscopes employs 02 fold parallel signal processing which ensures high acquisition rates, even for complex signal nalysis. a The results are available quickly and are based on a large number of waveforms that provide statistically meaningful information. High measurement speed, even for complex analysis functions Standard functions such as mathematical operations, mask tests, histograms, spectrum display and automatic measurements require additional computing time. If they are implemented in software, the blind time increases...

The ability to overlap the FFT means that the R&S®RTO oscilloscopes are also able to correctly display intermittent signals such as pulse-type interferers. Particularly when operating the oscilloscope in persistence mode, users can see what is really happening in the measured signal. As in spectrum analyzers, operation is based on entering the center frequency, span and resolution bandwidth. The numeric grid annotation is particularly user-friendly. Measurements such as total harmonic distortion (THD) and power spectrum density (PSD), which are usually the realm of spectrum analyzers, can...

Highly accurate digital trigger system Precise measurements due to low trigger jitter Conventional oscilloscopes use an analog triggering architecture. They divide the analog measurement signal in the frontend, and process it in separate trigger and acquisition paths. However, these different signal paths cause time and amplitude offset. This results in measurement inaccuracies that cannot be completely corrected by postprocessing. Due to the use of hardware-based signal processing, the digital trigger system used in the R&S®RTO oscilloscopes is the first to operate in realtime. It...

High trigger sensitivity at full bandwidth The digital trigger can validate every acquired sample against the trigger definition. For this reason, the R&S®RTO oscilloscopes are able to trigger on even the smallest signal amplitudes. In order to achieve stable triggering regardless of signal noise levels, the user can set a trigger hysteresis for the oscilloscopes. And due to the low-noise frontends, the oscilloscopes can also trigger on signals with vertical input sensitivities of < 10 mV/div at full measurement bandwidth. Adjustable digital filter for the trigger signal The digital trigger...

Color-coded control elements for clear ser u guidance The controls for the vertical system and the trigger ystem s are color-coded. Multicolor LEDs around the knobs for vertical positioning and scaling visualize the currently selected channel in the appropriate color. The color coding matches the waveform display and the result windows on the screen. The clear allocation enables smooth work, even with complex measurement tasks. Signal icons with drag & drop functionality When working with multiple signals, the screen becomes easily cluttered. This is not the case with the oscilloscopes...
