The receptor probe (calibrated for use with oscilloscope) is assembled with a hinged construction allowing it to be placed around the cable under test. The design of this probe includes a calibrating resistor mounted in the housing. This resistor has been adjusted so that the display on the associated oscilloscope accurately indicates the value of spike current detected.
Solar Electronics 7541-1 ApplicationsThe design requirements for electrical equipment on board the Space Shuttle vehicle include cable induced currents, called “indirect lightning effects” as described in Rockwell International Specification MF0004-002. A system for providing “component number one” described in Figure 15(b) of that specification has been developed and include the 7541-1 Spike Receptor Probe.
