Connecting the NI 9770 to a Device Under Test
You can connect the NI 9770 to the equipment under test through
a current transformer. The current transformer provides electrical
isolation between the equipment under test and the NI 9770 and
allows the NI 9770 to measure high-frequency currents flowing
into the ground connection of the equipment under test.
