Front-Panel Features

Figure 3-1 Front-Panel Features of the HP 8517B Test Set
Front-Panel Description
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.
This LED is lit when the test set line switch is ON and not lit when the test set line switch is OFF.
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.
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.
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).
