This
field
is
always
set
to
use
“Auto”.
Auto
mode
will
automatically
decide
which
converter
to
use
based
on
the
selected
frequency
list.
The
12
‐
bit
converter
is
used
if
all
frequencies
in
the
list
are
less
than
100
MHz.
A
switching
algorithm
is
used
for
a
list
that
contains
frequencies
ranging
from
307
kHz
‐
100
MHz.
Fundamental —
Enter
a
custom
generator
frequency
or
select
from
the
list
of
generator
frequencies
commonly
used
in
the
semiconductor
industry.
Note:
Select
all
other
options
for
the
fundamental
before
adding
it
to
the
list
of
selected
frequencies.
Options
include
harmonic
selection,
intermod
selection,
and
tolerance
settings.
F2 Frequency —
Select
another
fundamental
from
the
list
to
use
as
the
“F2”
frequency
in
an
intermodulation
product.
Note:
The
F2
frequency
must
have
already
been
added
to
the
selected
frequencies
list.
Note:
An
intermod
is
combination
of
two
frequencies
in
the
form:
IMD
=
F1+nF2,
where
n
is
one
of
{
‐
3,
‐
2,
‐
1,1,2,3}.
