POSU

prede￿ned function in its syntax diagram. When POSU is used as a source, the position-unit value of the source is used for operation by the command that contains POSU. POSU converts the wavelength of the reference-trace element to position units when the trace is displayed in wavelength spans greater than zero. For spans equal to zero, POSU converts the sweep-time position of the trace element to position units. If the reference trace is not speci￿ed, the last active trace is assumed to be the reference trace.
