ABSTRACT:
A system for transmitting traces of an oscilloscope (16) to a remote location for analysis comprises a transmitter circuit (18) which digitizes and transmits the traces to the remote location via a first modem (20), and a receiver circuit (24) at the remote location, for receiving via a second modem (22) the transmitted signals and delivering these signals to a destination oscilloscope (26). At the transmitting location, the vertical output signal of the oscilloscope is amplified and fed to an analog-to-digital converter. The digitized output signal of the converter and the oscilloscope's timebase gate signal are stored in a memory circuit and subsequently transmitted to the remote location via the first modem (20). At the remote location, the receiver circuit (24) comprises a universal asynchronous receiver transmitter (UART) interfacing with the second modem (22), a memory circuit for storing the transmitted signals, and associated circuitry for restoring the oscilloscope signals's amplitude. The timebase gate signal of the transmitting oscilloscope (16) is used to trigger the destination oscilloscope (FIG. 1).
