(1)

Line Switch

This switch turns the test set on or off. When the side of the switch labeled “0” is depressed, the

 

 

test set is OFF; when the side labeled “1” is depressed, the test set is ON.

 

 

 

(2)

Line LED

This LED is lit when the test set line switch is ON and not lit when the test set line switch is OFF.

 

 

 

(3)

Active LED

This LED lights about two seconds after power is turned on, following the successful conclusion of

 

 

the self-test. If the test set is used with other test sets (Option 001) and is not addressed by the HP

 

 

8510C, then this light remains off.

 

 

 

(4)

Port 1

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

 

 

RF energy from the DUT. The reflected RF energy is coupled to a sampler within the instrument.

 

 

Connections made to this input must be torqued to 90 N-cm (8 in-lb), and no more.

 

 

 

(5)

Bias Fuse

The fuses that limit bias applied to Port 1 and Port 2 are located in these holders (see the

 

 

instrument front panel or the replaceable parts list for the fuse values).
