FULL 2-PORT Displays the

series of

menus used

to perform

a complete

calibration to

measure

all

four

S-parameters of

a two-port

device.

This is

the most

accurate calibration

for measurements

two-port devices

.It

eectively reduces

all correctable

systematic errors

(directivity,

source

match,

load match,

isolation, reection

tracking, and

transmission tracking)

in both

the

forward

and

the

reverse direction.

Isolation correction

can be

omitted for

measurements of

devices with

limited

dynamic range
