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.
