IUT has constant low noise input:
auto integration not required

There
is no need for
the auto impedance facility,
as the form of the
circuit is known.
RANGE
auto Covers all
input voltage ranges.
COUPLING
dc IUT gives no
dc
component
at Voltage 1 input, therefore
dc
coupling is
used
for minimum
phase
shift.
INPUT

IUT gives no
dc component at CURRENT input,
therefore
