The purpose of this device is to create hard or even impossible to trigger pulses.

It supports 3.3V and 5V voltage levels using a analog multiplexer chip.

The protoboard is available at elecfreaks.com - quite good stuff.

Tektronix 314 - back cover removed

I heard a strange noise when I used it the last time. Something was sliding back and forth in there. Still I used it last time. After removing the back cover it turned out that 2 metal screws were completely loose.

As you can see in the photo, they could have shorted out quite a lot of things in there. Call me stupid.
