Buffered Mult with integrated cable tester and manual gate
The Bufftest is an extremely accurate buffered mult with a clever little circuit that lets you turn it into a cable tester at the push of a button. It can also be patched as 3x manual gates and, if you can find a use for it, 3x negative gates. Bi-colour LEDs indicate voltage.
To use as a cable tester, patch cable to be tested from any of the top outputs to the bottom input. When the test button is pressed the top LED will light green to indicate a positive voltage output, the bottom LED will indicate the state of the cable being tested. Green indicates the signal is good, red indicates the signal is broken and off indicates signal and ground are shorted.
Following user feedback from the LRMSMSLR the BuffTest has a footprint for a shrouded power header. Reverse power protection is provided by a pair of diodes.
Front panel is PCB material with black soldermask and ENIG gold lettering. Secondary labelling is printed in the copper under the soldermask so it looks embossed. Also lightning bolts.
