Reading a Measurement
5-16.
To read a measurement from the counter to a calculator, the counter must first be
addressed to talk and the calculator to listen. The examples below indicate how a calculator may
read a measurement from the counter.

Note that the data output string from the
5328A
may includea leading
"0"
when a counter
measurement overflows. The
9830A
example above includes the format specification
"X"
so that
calculator will skip over the first character and not be confused by the letter
"0".
The examples
that follow show how a calculator may also read in the value of the leading character:
5-18.
In these examples,
A
contains the decimal value of the leading character; B contains the
valueof the reading. If the leading character
is
"SP" then
A=32;
if the character
is
"0"
then
A=79.

PROGRAMMING EXAMPLE
5-20.
The following program illustrate how the HP
982OA/2lA
and
983OA
calculators can control
the
5328A
counter. Both programs cause the counter to make a series of frequency measure-
ments. The calculator reads the measurements into memory and prints the results. The programs
assume the counter talk address is
"J"
and listen address
"*".
