Abstract A simple personal computer‐based signal‐averaging, linked scan control unit is described. The design is built around a set of cascaded multiplying digital‐to‐analog converters. Examples of B, B/E and B 2 / E spectra of a small peptide, a mixture of phosphatidyl ethanolamines and cesium iodide clusters are given to illustrate the utility of both linked scanning and signal averaging.
