Abstract: Disclosed are a method, system, and/or apparatus to perform clock jitter and power supply noise analysis. In one embodiment, a method may include receiving a first signal, which may be a clock signal, then generating a second signal based on the first signal. The method may further include delaying the second signal by a base delay and/or a series of fine delays. The method may also include taking measurements of the delayed second signal and comparing those measurements to theoretical measurements of the second signal that would occur if the first signal were noise-free. The method may further include determining, based on the measurements and the comparison thereof, whether noise is present, whether the noise is high frequency or low frequency noise, and whether the noise is due to clock jitter and/or power supply deviations.

Abstract: Hand-carried, battery-powered light replacing conventional bank lights are described. In one embodiment, the light includes a generally rectangular body with opposed faces, a peripheral edge having a width substantially less than the width of the faces, and a handle adjacent one end of the body; and a plurality of spaced LED emitter heads mounted on one face of the body, each of the emitter heads including a housing and at least one LED emitter. In another embodiment, the light includes a non-conductive enclosure having rectangular top and bottom walls, and side and end walls connecting the top and bottom walls, the top wall including receiving recesses; and a plurality of rotatable light sources mounted on the top wall, each of the light sources including a telescopic support post having a base end pivotally attached to the top wall and an outer end, and an LED emitter head attached to the outer end of the post.
