Abstract
A vector generator was designed and built as a peripheral for a minicomputer. The vector generator is a device which accepts two endpoints and draws a straight line between them on some display device. While this could be done point-by-point by a minicomputer, it would use valuable computing power in an inefficient way. This generator is part of the Precision Signal Power Measurement (PSPM) System and is used to graph the power spectra of the signal measured to determine performance of spacecraft and ground telemetry transmitters and receivers. This hardware increases the graphing efficiency by an average of 4000 times over the pointby-point plotting method, requiring less than 15 ys of computer time per endpoint. The vectors are composed of points spaced 0.004 mm apart, providing excellent resolution and linearity.
