Oscillation

frequency

of

N

anoV

N

A

The

N

anoV

N

A

measures

the

reection

coecient

and

transmission

coecient

at

101

points

in

the

measurement

frequency

band.

The

local

frequency

of

N

anoV

N

A

is

kHz

to

MHz.

Frequencies

above

this

use

harmonic

mode.

The

fundamental

wave

is

not

attenuated

even

in

harmonic

mode.

The

usage

modes

for

each

frequency

are

as

follows.

Up

to

MHz:

fundamental

wave

From

MHz

to

MHz:

rd

harmonic

MHz

to

MHz:

th

harmonic

Especially

when

checking

the

gain

of

the

amplier,

it

is

necessary

to

be

careful

that

the

fundamental

wave

is

always

input.

The

input

is

in

each

case

converted

to

an

intermediate

frequency

of

kHz.

The

signal

is

analog-to-digital

converted

at

kHz

sampling.

The

digital

data

is

processed

by

the

MCU.
