The following details shall apply: (a) Method of Connection - Attach current and voltage leads where shown in Figure 4. (b) Test Voltage - 20 millivolts DC max open circuit. (c) Test Current - Not to exceed 100 milliamps. 6.2 Ground Terminal to Shield Contact Resistance The ground terminal to shield contact resistance shall not exceed 8 milliohms (14 milliohms after environmental exposure) when measured in accordance with MIL-STD-1344A, Method 3002.1. The following details shall apply: (a) Method of Connection - Attach current and voltage leads where shown in Figure 4. (b) Test Voltage - 20 millivolts DC max open circuit. (c) Test Current - Not to exceed 100 milliamps. 6.3 Shielding System Performance Shielding system performance varies with frequency, and should be evaluated for each special application. The following table is representative of typical responses when measured using a swept frequency response method as described in BUS-03-107. The response from the cable is measured with a current probe sensor with the spectrum analyzer set to the "maximum hold" function. The difference in response from an unshielded reference cable assembly and the shielded cable under test is defined as the shielding performance of the connector.
