Analysing the frequency response of a device, using Bode plots, is available now for selected Rohde & Schwarz oscilloscopes. With a new software option, users can analyse the response to frequency changes from 10Hz up to 25MHz without any additional piece of equipment and at a fraction of the price of dedicated solutions.
Equipped with the R&S RTx-K36 software option, the RTB2000, RTM3000 and RTA4000 oscilloscopes can display Bode plots for both phase and gain against frequency simultaneously.
For performing control loop response and power supply rejection ratio (PSRR) measurements, or for characterisation of passive components, the vector network analyser-based methods often do not cover frequencies under 9 kHz, or are simply too costly for smaller budgets.
When using an R&S RTB2000 entry-level oscilloscope, it is possible to make frequency response measurements from 10Hz at almost half the price previously offered on the market.
Apart from the conventional time domain measurements available with oscilloscopes, and the wide range of general-purpose measurements supported, with the new Bode plot application the R&S RTB2000, R&S RTM3000, and R&S RTA4000 can also perform gain and phase frequency response analysis.
All three oscilloscope families come equipped with 10-bit ADCs not available on other oscilloscopes in their class, enabling superior vertical dynamic range compared to existing oscilloscope-based solutions.
The R&S RTx-K36 frequency response analysis (Bode plot) is now available from Rohde & Schwarz and selected distribution channel partners. Pricing of the software option starts at €490 for an R&S RTB2000 oscilloscope.
