Abstract

A method which can obtain a digital representation of cyclic analog dat containing frequencies exceeding the resolution capabilities of the 7406 Analog Input Module has been developed. The method is similar to that used by a sampling oscilloscope, and uses the capabilities of the 7406 Digital Input Module (DIM), Digital Output Module (DOM), Analog Input Module (AIM), and Analog Output Module (AOM) to complement the simple TTL (transistor-transistor logic) circuit required for this type of sampling. An IBM 5110 or 5120 computer system using APL and appropriate microcode is used for the data acquisition and control functions.
