Table 3-2 Rear-Panel Descriptions

(1)	Line Module	Houses the line cord connector, line fuse and line voltage selector. Pull out the right side
		of the line module cover to replace or change the fuse or to change the voltage selection.
		Remove the voltage selector drum to rotate it to a different voltage setting. Recommended
		fuse values are printed on the rear panel.
(2)	RF Input	A 2.4 mm connector that receives RF energy from the source. Connections made to this
		input must be torqued no more than 90 N-cm (8 in-lb).
(3)	J10 Test Set Interconnect	Used only in test sets with Option 001. It allows connecting another test set to the option
		001 test set. Up to four test sets can be serially connected to the analyzer. The HP 8510C
		system automatically selects the IF output from the chosen test set for processing and
		display. Refer to “Controlling Multiple Test Sets” in this chapter for more information.
(4)	J11 Test Set Interconnect	Transmits the IF signal from the test set to the HP 85102 IF detector. It also transmits
		control signals bi-directionally.
(5)	HP 8510 System Bus Address Switch	A five-pole binary-weighted switch sets the test-set’s system bus address. The binary
		weight of each pole is indicated on the rear panel. So are the On and Off positions. The
		default setting is decimal twenty (off-off-on-off-on, from left to right).
