ABSTRACT:
A device readily adaptable into existing laboratory oscilloscopes for causing the current date and time of day to be displayed on the screen thereof. In a preferred embodiment, the analog read out comprises ten digits across the top of the oscilloscope screen and respectively represent years, hundreds of days, tens of days, days, tens of hours, hours, tens of minutes, minutes, tens of seconds, and seconds. The device essentially comprises a time-keeping module for generating binary coded decimal signals representative of the date and time data, a slightly modified standard oscilloscope keyboard read out plug-in unit, and, of course, the oscilloscope itself. Initialization of the data may be accomplished by manually operable thumbwheel switches located on the time-keeping module. The device keeps time to an accuracy of about one-fifth second per day and is extremely useful when precise time recordation of remotely obtained data is necessary.
