Input/Output
CAUTION When operating in dc coupled mode, ensure protection of the input
mixer by limiting the input level to 0 Vdc, +30 dBm.
CAUTION To prevent damage to the EMC analyzer from power line switching
transients:
— Disconnect the receiver input from the LISN (or current clamp)
output prior to connecting or disconnecting the mains to the EUT.
— Disconnect the receiver input from the LISN (or current clamp)
output prior to turning the EUT on or off.
— If you are using a switchable LISN, disconnect the receiver input
from the LISN output prior to switching the LISN between lines.
— Disconnect the receiver input from the current clamp output prior to
attaching or detaching it to a powered EUT main.
