Abstract

A conductor is formed in a serpentine path on a flexible sheet. The sheet is easily wrapped around a cable with the lengthwise direction of the wires parallel to the length of the cable. The ends of the conductor are connected to a device that produces a signal that simulates electrical noise. If the cable is susceptible to electrical noise in normal operation, an observable fault will occur in the apparatus associated with the cable.

Wrap On Coupler for Cables for Test of Electrical Noise Susceptibility

A conductor is formed in a serpentine path on a flexible sheet. The sheet is easily wrapped around a cable with the lengthwise direction of the wires parallel to the length of the cable. The ends of the conductor are connected to a device that produces a signal that simulates electrical noise. If the cable is susceptible to electrical noise in normal operation, an observable fault will occur in the apparatus associated with the cable.

The electrical cables that interconnect apparatus of a data processing system may pick up electrical signals that cause faults in the apparatus. Test devices simulate various sources of electrical noise. Conventionally, a coil of wire is connected to be energized by a test device and is held or clamped to the cables with the wires of the loop parallel to the length of the adjacent section of the cable so that the loop is capacitively and inductively coupled to the cable. If the cable is susceptible to electrical noise, the test will produce faults in the operations of the data processing apparatus. When a cable is identified that causes a fault during this test, it is further shielded or its location is adjusted until no further faults occur during the test.

The drawing shows a sheet of material 2 and the conductor 3. The sheet can be made of flexible dielectric, such as nylon.
