Solartron 1260 - Assigning Fixed Values

3.6 SCALING
FUNCTION EXAMPLE
A practical
example
shows how
scaling
functions work.
In this
particular
case
the
open-loop
gain
(A) of an amplifier
is
computed from
the
closed-loop
gain
(A
'),
using
the function
where
A-
A’
1 -RA'
and
A*
=
V
o
v~
R.
R
input
R
feedback
Note
that all
functions
use
vector
arithmetic,
i.e. VI
=
a
+
jb
3.6.1 Assigning
Fixed
Values
Fixed
values
are assigned
to a function from
stored
results
(Sn)
and
user-defined
constants
(Cn). In the present
example,
therefore, the
values
"1”
and
R are
stored
as
constants.
This
is done before
entering the function
itself.
The
procedure is:

Press the
CONSTS

assign
the
intended
constant
a number...
...i.e. 1.
Enter the number...
...and the
form of
the intended
constant
is
displayed.
