In order to connect a Pin PMU to the corresponding DUT pin the Pin
PMU relay has to be closed (see also
Connect Sequence" on page
The Pin PMU returns pass/fail signals to the test processor. Two
compare voltage levels received from the level generator are used as
thresholds.
In addition the DC signal may be converted into a digital value in order
to do an analog measurement rather than a pass/fail measurement.
However taking analog readings is not optimized for highest
throughput, 16 channels share the analog to digital conversion unit, as
shown in

PPMU can operate in all four quadrants that are possible when forcing
voltages or currents (sinking or sourcing currents at positive or nega-
tive voltages).
