(6) a1 LED

This LED indicates that the test set is internally switched to the S11 or S21 mode and source power

 

is switched to Port 1.

 

 

(7) a2 LED

This LED indicates that the test set is internally switched to the S22 or S12 mode and source power

 

is switched to Port 2.

 

 

(8) Port 2

This test port transmits RF energy from the source to the DUT and receives reflected or transmitted

 

RF energy from the DUT.

 

 

 

Rear-Panel Features

Figure 3-2 Rear-Panel Features of the HP 8517B Test SetTable 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).
