    The R&S®RTE1000 and R&S®RTM3000 oscilloscopes provide the right tools to quickly analyze the CMN of an EPS. With an external highpass filter and a standard-compliant load, the R&S®RTE1000 and R&S®RTM3000 can analyze a large set of SMPS pulses to check conformance. The example here shows a negative pulse. Positive pulses can be analyzed in the same manner.
