The SPARQ Signal Integrity Network Analyzer uses TDR and TDT to characterize a network’s electrical behavior. The process to measure S-parameters includes 3 phases: 1) OSLT calibration, 2) DUT measurement, and 3) S-parameter calculation. When using “E” model SPARQs, all phases are done automatically, with a single button press, and without any user intervention whatsoever. This is accomplished by using an internal switch matrix assembly that routes signals to internally connected calibration standards and to the front panel ports. “M” models are calibrated with a user’s external OSLT calibration kit.
