The key decider will be the frequency of the signals to measure. The oscilloscope bandwidth will determine the maximum frequency that can be measured. The rule of thumb for the bandwidth is three to five time the frequency to be measured. In addition, the measurement scenario plays a major role to find the right oscilloscope. The Rohde & Schwarz oscilloscope portfolio includes solutions for both general purpose measurements and specific industry standards. It covers:
Entry level oscilloscopes with bandwidths from 50 MHz to 1 GHz to suit budgets from introductory education to professional use, including comprehensive update possibilities, such as the R&SRTC1000. General purpose bench oscilloscopes with deep memory and smart analysis options, such as frequency response analysis using Bode plots, like the R&SRTB2000. High-performance oscilloscopes with bandwidths up to 16 GHz, real-time de-embedding, fast update rates, low noise, and unique high-performance digital triggers, such as the R&SRTP.
