3.2 Signal Connection
Depending on the mode of operation (PE or PMU), there are 3 leads per pin:
1.
Force-High (FH)
2.
Low (L)
3.
Sense-High (SH)
For PMU mode, Force-High and Low signals are where voltage and current are generated
during source or sink operation. Sense-High signals are high impedance paths. Connect these
lines as close to the DUT terminal as possible for more accurate voltage source or measure
operations. Presence of Sense lines at the DUT terminals is known as 4-wire, remote-sense, or
Kelvin operation.
For PE mode, Sense-High lines do not play any role. Digital signals are travelling via Force-High
and Low lines.
