Conducted Susceptibility, Power Leads, 30 Hz to 150 kHz
This test procedure is used to verify the ability of the EUT to withstand signals coupled onto input power leads. There are two methods provided for making measurements of the applied signal. The first uses an oscilloscope with a power input isolation transformer. The second uses a measurement receiver together with a transducer. The transducer is intended to electrically isolate the receiver from the EUT power and reduce the signal levels to protect the receiver.
The test equipment shall be as follows:
a. Signal generator
b. Power amplifier
c. Oscilloscope or measurement receiver
d. Coupling transformer
e. Capacitor, 10 μF
f. Isolation transformer
g. Resistor, 0.5 ohm
h. LISNs
i. Transducer for measurement receiver use
MIL-STD-461 CS109 Conducted Susceptibility, Structure Current, 60 Hz to 100 kHz

The test equipment shall be as follows:
a. Signal generator
b. Amplifier (if required)
c. Isolation transformers
d. Current probe
e. Measurement receiver
