The K7103 kit is a digital memory oscilloscope that can be used on an IBM compatible computer. It is operated from the computer using the computer screen as the oscilloscope display. All standard oscilloscope functions are available from the DOS program supplied. Operation seems like a normal oscilloscope with the one difference that most operations are performed using the mouse. A big advantage are the markers for indication of frequency and voltage.
Connection is via the parallel port of the computer.
Any waveform on the screen can be stored in TIFF format so that it may be later retrieved for use in documentation or for comparison to other waveforms. With some computers the scope does not seem to work. You can add them on the PC scope. Be sure to mount the capacitor as close as possible to R56.
