Multiple Loads

If you are using local sensing and are connecting multiple loads to

one output, connect each load to the output terminals using separate

connecting wires as shown in the following figure.

This minimizes mutual coupling effects and takes full advantage of

the power system's low output impedance. Keep each pair of wires as

short as possible and twist or bundle them to reduce lead inductance

and noise pickup.

Note that Agilent Models N678xA SMU have additional wiring

restrictions as discussed under “Agilent N678xA SMU Wiring

Requirements”.

If load considerations require the use of distribution terminals that

are located away from the instrument, connect the output terminals

to the remote distribution terminals by a pair of twisted or bundled

wires. Connect each load to the distribution terminals separately.

Remote voltage sensing is recommended under these circumstances.

Sense either at the remote distribution terminals or, if one load is

more sensitive than the others, directly at the critical load.
