6 7. Electorstic discharge 7.1 Test Each front-end must be capable of normal performance following its subjection to the following tests: MIL STD 883C HBM Test is performed with a voltage discharge from a 100 PF capacitor over a 1500 OHM series resistance in the discharge path. There is a direct contact between the test probe head and the unit under test, using the test points and conditions detailed below: o Test to pins 1 through 22: 3 successive ESD discharges of +/-2 KVDC between each pin and the front-end frame. IEC Test is performed with a voltage discharge from a 150 PF capacitor over a 330 OHM series resistance in the discharge path. There is a direct contact between the test probe head and the unit under test, using the test points and conditions detailed below: o Test for antenna input socket +/-8 KVDC 7.2 Handling Anyone handling a front-end must wear a properly grounded anti-static discharge bracelet to minimize ESD damage. After each front-end is aligned and tested, it will be packed with anti-static material prior to transportation and storage. This package is to remain in place until the front-end is assembled and soldered onto the receiver main board. May.09,
