S-parameters, Quick VNA measurements begin with the unpleasant and complex task of calibration. This involves multiple connections that can produce misleading results due to operator error. The SPARQ provides calibrated measurements with a single connection to the DUT and offers simple setup choices. Start and complete the entire measurement with a single button press. I nternal Calibration SPARQ takes a revolutionary approach to calibration by building in calibration standards. This enables measurements to be made without multiple connection steps and removes the need for additional electronic...

5 I ncludes the Tools That You Expect A signal integrity network analyzer should include well-integrated tools for providing measurement and analysis in both time and frequency domains. Signal integrity requires more than just S-parameters; the time domain offers important insight as it shows the performance of the S-parameter models in simulation. SPARQ includes standard all of the hardware and software tools needed to make signal integrity measurements right out of the box. These tools include capabilities that cost extra on most instruments. Mixed-mode S-parameter conversion and port renumbering,...

6 Streamlined Setup The simple setup shown in the main setup screen above is all that is needed to configure a SPARQ measurement. You provide the frequencies and number of ports and then go. Helper information like time length assist in frequency spacing choices, and DUT length mode choices control the pulser repetition rate for faster measurements. Various measurement sequence control modes allow for trade-offs between precision and speed, and helper information provides an estimate of the measurement time. All measurements proceed automatically without user intervention. Advanced screens are...

7 From Measurement Directly to Simulation S-parameters present many difficulties for time domain simulators. These difficulties come from the two ends of the frequency spectrum. Lack of a DC point and truncation of the high frequency content causes simulation problems. Since it is based in the time domain, SPARQ provides a DC measurement point and 40 GHz frequency content so that simulators come up with the right answer. SPARQ provides enforcements of passivity, causality and reciprocity to ensure physical measurement results and provides time domain views so that time domain behavior is verified...

ME ASUREME MEASUREMENNTTSS RRIIGGHHTT TTHHEE FFIIRRSSTT TTIMEIME 8 Advanced Features that Prevent Mistakes and Wasted Time A frustrating situation is to find that after spending the time to calibrate and take S-parameter measurements, something is wrong either because of a mistake or a poor connection. Sometimes it is hours or days before the problem is detected; that is hours or days of suspect data in use. Because SPARQ is TDR/TDT based, it can be used to provide basic troubleshooting before you get too far into the measurement. By driving the SPARQ in its native TDR/TDT mode, engineers can...
