DPS Personal V-Scope Vectorscope / Waveform Monitor 

Model DPS-560 WVF (Rev3) for Analog NTSC Standard Definition (SD) signals

Comes in original box (but not original packing) with Amiga software floppy disk

The Personal V-SCOPE is a combination waveform monitor and vector scope which provides precise real time monitoring of video signals. The V-SCOPE produces a digitally synthesized waveform/vector display, including graticules, which can be displayed on any video monitor. The V-SCOPE features a variety of display modes including simultaneous waveform and vector displays in either overlay or split screen modes.

The Personal V-SCOPE card is designed to work in an ISA expansion slot. The card only uses the slot to obtain power, no signals are passed. 

The Personal V-SCOPE has a single video input, a buffered video output, a waveform/vector superimpose output, and a full-time waveform/vector output.

The various display modes and features of the V-SCOPE can be controlled via software, but the only software I have found is for Amiga computers. Included is an original Amiga software disk. I have no idea if the disk is readable, but if not the software can be found online on the Amiga Hardware Database.

If you don't have an Amiga, the card can be set for its various display modes by setting DIP switches on the card. Again, search for the Amiga Hardware Database for settings.
 
This card has been tested and is working (see last photo).
