Section 4: Measurement Options Model 6517B Electrometer User’s Manual
EXTERNAL: Test will start when a trigger pulse (via EXT TRIG IN connector) is received
by the Model 6517B.
TRIGLINK: T
est will start when a trigger pulse (via TRIG LINK connector) is received by
the Model 6517B. You will also be prompted to s
elect the input line for the
trigger.
Connections
Test sequences use the force voltage measure current (FVMI) technique as shown in Figure 4-8.
This connection scheme assumes that V-Source LO is
internally connected to ammeter LO. This
connection is controlled from the METER CONNECT option of the CONFIGURE V-SOURCE
menu (see V-Source). Note that Figure 4-8 does not meet the exact connection requirements for
all the tests. It is only intended
to show the general concept. More specific connection diagrams
are provided in the Reference Manual.

WARNING Hazardous voltages may be present on the output and guard terminals. To
prevent electrical shock that could cause injury or death, NEVER make or
break connections to the Model 6517B while the output is on. Power off the
equipment from the front panel or disconnect the main power cord from the
rear of the Model 6517B before handling cables connected to the outputs.
Putting the equipment in standby mode does not guarantee that the outputs
are not powered if a hardware or software fault occurs.
