Once
all
desired
changes
have
been
made
,
the
program
will
ask
if
you
want
to
store
the
data
just
entered.
A
specic
4-character
le
name
sux
can
be
provided
if
more
than
one
conguration
is
required.
Leaving
the
le
name
blank
will
result
in
the
default
le
name
of
\Cfg

If
the
program
nds
only
one
cong
le
,
that
le
will
be
loaded
automatically
.
If
more
than
one
is
discovered,
the
program
will
list
the
le
names
found
and
allow
you
to
choose
one
.
At
this
point
the
program
will
also
ask
you
if
a
hardcopy
printout
is
desired.

After
the

been
generated,
the
proper
data

containing
the
correction
values
must
be
generated.

CAL
DATA
ENTRY
.
Y
ou
will
be
shown
a
list
including:
3
sensors
a
step
attenuator
two
20
dB
attenuators
(pads)
Y
ou
will
need
to
enter
the
correction
data
for
every
piece
of
test
equipment
included
in
this
list
that
you
will
be
using
to
test
the
analyzer
.
Select
the
desired
item.
Sensors
.
All
sensors
require
both
frequency
and
cal
factor
data.
Frequencies
must
always
be
in
MHz
and
cal
factors
in
percent.
The
rst
entry
requested
will
be
the
last
four
digits
of
the
serial
number
.
The
computer
will
search
for
a
current
conguration
le
containing
this
information.
If
one
is
present,
the
program
will
query
you
to
either
view
or
edit
the
old
values
.
Assuming
you
are
editing
the
data,
the
50
MHz
reference
cal
factor
will
be
requested
next.
This
value
must
use
percent
as
its
units
and
be
within
the
range
of
50
and
150
percent.
After
the
cal
factor
is
entered,
the
program
will
request
that
all
frequency/cal
factor
pairs
be
entered.
Y
ou
must
start
with
the
lowest
frequency
for
which
you
have
data
and
sequentially
enter
higher
frequencies
until
done
.
Each
entry
must
consist
of
both
a
frequency
in
MHz
and
the
cal
factor
in
percent,
separated
by
a
comma
(e
.g.
500,98.6).
Each
frequency
entered
must
be
higher
than
the
previous
entry
.
These
cal
factor
values
must
be
between
75
and
125
percent.
If
a
mistake
is
made
,
you
can
back
up
one
entry
and
re-enter
a
value
by
entering
a
negative
frequency
.
If
you
accidentally
enter
only
the
frequency
(instead
of
a
frequency/cal
factor
pair),
the
computer
will
wait
for
the
cal
factor
to
be
entered;
however
the
only
prompt
will
be
a
\?".
Each
entry
is
shown
on
the
CRT
.
When
all
entries
are
completed,
enter
\0,0"
to
exit
the
data
entry
portion
of
the
program.
At
this
point
the
program
will
re-display
all
values
entered
and
ask
if
you
want
to
store
them.
Note
Even
if
you
nd
a
mistake
,
it
will
be
easier
to
answer
yes
,
then
go
back
and
re-edit
the
values
,
otherwise
you
will
have
to
re-enter
all
values
again.
20
dB
Attenuators
(P
ads).
A
procedure
similar
to
the
sensor
data
entry
procedure
previously
described
is
used
to
enter
the
frequency/attenuation
values
for
the
20
dB
attenuators
.
V
alid
entries
for
the
20
dB
attenuator
range
from
17.5
to
23.5
dB
.
Step
Attenuator
.
Step
attenuator
data
is
only
measured
at
30
MHz
so
only
one
value
needs
to
be
entered
for
each
nominal
attenuation
step
.
All
values
are
relative
to
the
0
dB
setting,
which
is
dened
as
zero
(i.e
.
the
program
does
not
care
about
insertion
loss
at
the
0
dB
setting).
V
alid
entries
are
within
3
dB
of
the
nominal
attenuation
setting.
The
program
will
request
data
up
to
110
dB
of
attenuation.
