ScopeGrab - Fluke ScopeMeter Screen Capture


ScopeGrab is a Unix utility for capturing the screen of a Fluke ScopeMeter. It requires a cable to be connected between the serial port of the Unix machine, and the optical port of the ScopeMeter.

I have only tested this software and the optical cable using a Fluke 123 Industrial ScopeMeter. I cannot guarantee that it will work correctly with other ScopeMeter models. If you try it with another model, please let me know.

Sample screenshots:

ScopeGrab can save the screen in one of two formats, either Postscript or X11 bitmap format. The Postscript output defines it's own BoundingBox allowing easy insertion into other documents. Samples of each output are shown below:

Serial Cable:

The Fluke ScopeMeter has an optically isolated serial port, and uses a pair of infrared LEDs to transmit and receive data. A suitable serial cable can be manufactured using a conventional DB9 plug at one end, and by attaching a small PCB with an IR transmitter and receiver at the other end of the cable.
