Installation

Precautions

WARNING If this product is not used as speciﬁed, the protection provided by the

equipmentcouldbeimpaired. Thisproductmustbeusedinanormalcondition

(in which all means for protection are intact) only.

Electrostatic

Discharge

CAUTION The millimeter-wave controller and the test heads are sensitive to

electrostatic discharge (ESD). Ground your work station before unpacking

and installing the test heads. See “Electrostatic Discharge” on page 5-2 for

more information.

System Voltages All instruments in the 8510XF system must be set to the same voltage as the

system rack (either 120 Vac or 220 Vac). 120 Vac is the factory setting.

CAUTION The cabinet fans may be permanently damaged if a 120V system is plugged

into a 220V ac power outlet. The cabinet fans can be wired for either 120V

or 220V, but not both. Therefore, a system wired for 120V operation cannot

be switched to 230V operation simply by changing the voltage selection

switches on individual instruments.

Test Port Inputs

CAUTION Input power to the test ports must not exceed +27 dBm. Input power in

excess of this level will damage expensive components. Observe proper

precautions, especially when measuring ampliﬁers with gains of 20 dB or

greater.

Cleaning

WARNING To prevent electrical shock, disconnect the E734X/E735X mains before

cleaning. Use a dry cloth or one slightly dampened with water to clear the

external case parts. Do not attempt to clean internally.
