ESD Protection SpecificationTuner will be packed with anti - static poly foam to prevent the ESDdamage. Do not touch the tuner pins before grounding yourself. Anyonehandling the tuner must wear a properly grounded anti - static dischargebracelet.4-1. RF ConnectorTest is performed with a voltage discharge from a 150pF capacitor overa 330Ω series resistance in the discharge path. There is a direct contactbetween the test probe head and the RF connector with ± 8 KVDC.4-2. Module PinsTest is performed with a voltage discharge from a 150pF capacitor overa 330Ω series resistance in the discharge path. There is a direct contactbetween the test probe head and pin 1 through 11 with 3 successive ESDdischarges of ± 2 KVDC.
