DIGITAL STORAGE PC OSCILLOSCOPE KIT (K7103) Kit - Assembly Required

Any hobbyist's laboratory needs an oscilloscope but funds are usually insufficient for acquiring such a device. This kit represents a very good and cheaper alternative to anyone who already has a computer. 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. The oscilloscope has two completely independent channels (2nd channel is optional & not included) with a sampling frequency of 32 MHz. 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. The kit comes complete with housing (Assembly is required).

Hints
With some computers the scope does not seem to work. On certain parallel ports (especially on portable computers) pull up resistors have been omitted. You can add them on the PC scope. Connect two 4K7 resistors between lines 14-16 of the parallel port and the +5V supply.

If you experience communication troubles (frequency readout is not correct or samples seem to be missing) between the scope and the computer try adding a 120 pF capacitor between DB2 and ground. Be sure to mount the capacitor as close as possible to R56.
