Interlude #14: Making BNC to Jumper Pins Cables for My Oscilloscope | In The Lab With Jay Jay

In this video we make two cables for use with my oscilloscope or other devices with BNC sockets. The cables have a BNC connector on one end and two male jumper pins on the other end. This is so that I can easily connect my oscilloscope (or signal generator) to a breadboard.

Equipment which I might use these new cables with includes my Rigol MSO5074 Mixed Signal Oscilloscope and my UNI-T UTG962E Signal Generator.

In the video we use the METCAL PS-900 Soldering Station for soldering.

We use the EEVblog BM2257 Digital Multimeter to continuity test the cables and to check for shorts.

We use the Horusdy Soldering Station with Hot Air Gun for shrinking out heat shrink.

We use the Hakko CHP 3C-SA Precision Tweezers for pulling the heat shrink over the wire.
