If your measurements include losses caused by interconnects and fixtures, you won’t get the correct picture. While de-embedding — the process of mathematically removing the effects or fixtures and interconnects — has been around for years, the RTP series of oscilloscopes from Rohde & Schwarz lets you perform it in real-time. 

Real-time de-embedding lets the oscilloscope compensate for signal losses as part of the acquisition and display process, as opposed to applying post processing. That results in time savings, and even lets you trigger an acquisition on the de-embedded signal. De-embedding, in the form of digital filters, takes place immediately after the A/D converters in the oscilloscope’s architecture. For an additional explanation, see the video below, at 2:09.

Available in 4 GHz, 6 GHz, and 8 GHz models with 20 Gsamples/s sample rate on all four analog channels, the RTP series lets you construct eye diagrams for low and mid-speed serial buses. These bandwidths can’t reach those needed for buses above 5 Gbps data rates. The RTP series oscilloscopes compete with the Keysight Infiniium S-Series, Tektronix MSO/DPO7000 series, and Teledyne LeCroy WaveMaster 8084, 8086, and 8088 Zi-B series.
