9. Electrostatic Discharge
9.1 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 Ω 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:
• Test to pins 1 through LAST PIN:
3 successive ESD discharges of 2 KVDC between each pin and the front-end
frame.
IEC 1000-4-2
Test is performed with a voltage discharge from a 150 PF capacitor over a 330 Ω series
resistance in the discharge path. There is a direct contact between the test probe head and
the unit under test, using the test p
oints and conditions detailed below:
• Test for antenna input socket ± 8 KVDC
9.2 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 poly foam or
material prior to transportation and storage. This protective foam is to remain in place until
the front-end is assembled and soldered onto the receiver main board.
