connector

located

to

the

right

of

the

EUT

Power

Port

is

for

connecting

the

Spectrum

analyzer

or

EMI

receiver

for

making

conducted

measurements.

6.4

Test

lead

selection

switch

(Line

/

LI

or

Neutral

/

L2)

This

switch

allows

measurement

of

noise

from

each

line.

The

line

that

is

not

being

measured

is

automatically

terminated

internally

by

a

50

Ω

terminator.

However,

the

power
