Rohde & Schwarz has added the new entry-level R&S HMO1202 mixed-signal oscilloscopes to its R&S HMO1002 oscilloscope family. The instruments are ideal for use in the development of embedded designs and are tailored to the needs of users in research, education and service. The mixed-signal oscilloscopes are able to analyze serial SPI buses on digital channels while simultaneously monitoring two analog signals referenced to the transmitted SPI data. All that is needed is the separately available R&S HO3508 logic probe from Rohde & Schwarz, which is compatible with all R&S HMO oscilloscopes. Broad palette of built-in signal analysis functions - The company has packed numerous math functions into the new oscilloscopes, from simple standard operations such as add, subtract and divide to logarithmical differentiation and integration of waveforms. A formula editor is also available for entering a variety of calculation functions, such as integrating waveforms to determine the charge on a capacitor. The built-in FFT analysis functions with their 128 kpoints are equivalent to those found on larger oscilloscopes. Time domain signal, measurement window, result and analysis range are displayed in a single window, greatly facilitating spectral measurements. FFT analysis can even be performed on recorded signals, making it possible to analyze segments of interest by varying the window width. Pattern generator for developers of embedded designs - The integrated pattern generator generates protocol messages at up to 50Mbit/s. Developers can supplement the predefined messages by programming their own signal patterns of up to 2 kbit in length. This enables them to emulate circuit components that are not yet available, such as sensors. With numerous other functions for mask-based pass/fail tests as well as the high waveform update rate of 10 000 waveforms/s, the R&S HMO1202 oscilloscopes are ideal for developing numerous electronic circuits, says the company.
