The Generator stores the learn string in the
memory location designated
by the memory
location code. If the memory location
specified is
99,
the instrument
is programmed to the data
sent in the learn string.
Example:
To program the Generator
to the
Instrument
Preset State:
‘‘LI99BOABAAAAPPJMAAAICAAAAAAAABBOBKDAAAAAPECEAABPEAAABAAC
EBBAGCLKKABAEAM”
Note that the
binary learn string in this example is
the same as the learn string returned from
memory
location
98,
which contains
a
record
of the Instrument Preset State.
Instructions:
1. Convert the hexadecimal
number to a signed decimal number
as follows:
a. Multiply the most significant
hexadecimal digit
by
16.
b. Add the next significant
digit to the value obtained
in step a.
c. Multiply the sum of step
b by
16,
and add in the next hexadecimal
digit until the
least significant
hexadecimal digit has been
added.
NOTE
If
the
hexadecimal number started with an
8
through
F, the number is
negative.
Perform step
d
for negative
numbers.
d. Subtract 16 from the number raised to the power of the number of
digits.
Example
of Instruction 1:
To convert
hexadecimal number IE:
(1
*
16}+ 14
=
30
(Since the
most
significant digit
is
1,
the
number
is not negative.)
To convert
hexadecimal number FF9C:
{{{{(15
*
16)
+
15)
*
16)
+
9)
*
16)
-M2
=
65436
(Since the most significant digit is F, the number is negative.)
Using Step d; 1
6“’
=
65536,
65436
-
65536
=
-100.
The signed decimal equivalent to FF9C is
-
100.
2. Amplitude
quantities have a number and a resolution associated with
them. This
applies to the Displayed Amplitude, Reference Amplitude, and Amplitude Step.
Use the
following procedure
to identify the resolution of an
amplitude quantity;
a. If the resolution is A or B (hexadecimal), the resolution of the number is 0. 1 dBm
or 0.1 dB units.
