By Benjamin Dannan and Steven Sandler, Picotest.com Introduction and Application Optocouplers and optoisolators are very common semiconductor devices that allow an electrical signal to be transmitted between two isolated circuits. These devices are used to provide essential input/output isolation for protection and safety between a safe and a potentially hazardous or electrically noisy environment [1]. Some typical applications for optocouplers include microprocessor input/ou

Background A TDR measurement (Time Domain Reflectometry) measures the reflections that result from a signal traveling through a transmission environment of some kind - a circuit board trace, a cable, a connector, and so on. In the past, a TDR was often a large, expensive instrument that included a high-speed edge pulse and a sampling oscilloscope. Today, TDR remains a great tool for maintaining signal integrity, used extensively to qualify vendor stack-ups, such as identifyin

Background Today, voltage regulator modules (VRM) (and power supplies) need to supply power to multiple VDD cores to support FPGAs and/or custom ASICs using multi-gigabit ethernet, PCIe, and DDR memory interfaces. With that being said, vendor information for a VRM’s output impedance is not available and is not always accurate when it is supplied. Further, measuring ultra-low impedance on multiple VRMs or multi-topology DC-DC regulators is a challenge for any design engineer.
