Preparing the Analyzer for Use

	Power Cable and Grounding Requirements
	On the GPIB connector, pin 12 and pins 18 through 24 are tied to chassis
	ground and the GPIB cable shield. The instrument frame, chassis, covers,
	and all exposed metal surfaces including the connectors’ outer shell are
	connected to chassis ground. However, if channel 2 in the IF section is
	not installed, the channel 2 BNC connector’s outer shell is not connected
	to chassis ground.
	DO NOT interrupt the protective earth ground or ‘’float’’ the analyzer.
Warning
	This action could expose the operator to potentially hazardous
	voltages.
	The analyzer is equipped with two three-conductor power cords which

	ground the analyzer when plugged into appropriate receptacles. The
	type of power cable plug shipped with each analyzer depends on the
	country of destination. The following figure shows available power cables
	and plug configurations.
