BNC to 4 mm plug Screened Twisted-Pair Cable

The TA039 screened twisted pair cable is use this cable to connect a signal directly to the oscilloscope. A positive signal will be displayed when you connect the red BNC plug to the more positive signal and the black BNC plug to the more negative signal. If you connect these the wrong way round, the oscilloscope will not be damaged but the signal will appear inverted on the scope display.

Insert the grounding plug into one of the ground sockets on the front of the oscilloscope. This grounds the screen of the cable to prevent it from picking up electromagnetic noise that might otherwise interfere with the signal.
