4. esd protectionspecification
tuner will be packed withanti - static poly foam to prevent the esd damage. do not touch thetuner pins before grounding yourself. anyone handling the tunermust wear a properly grounded anti - static dischargebracelet.
4-1. rfconnector
testis performed with a voltage discharge from a 150pf capacitor over a330?series resistance in thedischarge path. there is a direct contact between the test probehead and the rf connector with ± 8 kvdc.
4-2. modulepins
test is performed with a voltage discharge from a150pf capacitor over a 330?series resistance in thedischarge path. there is a direct contact between the test probehead and pin 1 through 11 with 3 successive esd discharges of ± 2kvdc.
