ESD Protection Specification Tuner will be packed with anti - static poly foam to prevent the ESD damage. Do not touch the tuner pins before grounding yourself. Anyone handling the tuner must wear a properly grounded anti - static discharge bracelet. 4-1. RF Connector Test is performed with a voltage discharge from a 150pF capacitor over a 330Ω series resistance in the discharge path. There is a direct contact between the test probe head and the RF connector with ± 8 KVDC. 4-2. Module Pins Test is performed with a voltage discharge from a 150pF capacitor over a 330Ω series resistance in the discharge path. There is a direct contact between the test probe head and pin 1 through 11 with 3 successive ESD discharges of ± 2 KVDC.
