Creating and Downloading E443xB Waveform Data Using HP Basic for
UNIX
This programming example’s name is “
e443xb_hpbasicUx2.txt
.” This example
is not included on the Documentation CD.
The following program shows you how to download waveforms using HP
BASIC for UNIX. It is similar to the previous program example. The difference is
the way the formatting for the most significant bit (MSB) on lines is handled.
First, the I waveform data is put into an array of integers called
Iwfm_data
and
the Q waveform data is put into an array of integers called
Qwfm_data
. The
variable
Nbytes
is set to equal the number of bytes in the I waveform data.
This should be twice the number of integers in
Iwfm_data
, since an integer is
represented 2 bytes. Input integers must be between 0 and 16383.
In the
Output
commands,
USING “#,K”
formats the data. The pound symbol
(
#
) suppresses the automatic EOL (End of Line) output. This allows multiple
output commands to be concatenated as if they were a single output. The “K”
instructs HP BASIC to output the following numbers or strings in the default
format.
