Abstract : A new system is described for digital recording of analog signals in the microsecond range. The equipment is built around a Biomation 610 transient recorder and takes advantage of the fast response of the instrument's analog to digital converter. The wide frequency range of the system (dc to 2.5 MHz) permits digital recording of a rapidly changing nonrecurrent signal with storage on punched paper tape as an intermediate step prior to further analysis. Some of the design features are discussed. The equipment is being used in pulse radiolysis studies to digitize photoelectric signals corresponding to the changing optical absorption properties of short-lived chemical species. (Author)
