Creating and Downloading E443xB Waveform Data Using HP Basic for
UNIX
This programming example’s name is “e443xb_hpbasicUx2.txt.” T h is e x a mp l e
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.

Program Comments
10: Program file name.
20 Sets the number of points in the waveform.
30: Defines arrays for I and Q waveform points. Sets them to be integer arrays.
40: Sets HP BASIC to use degrees for cosine and sine functions.
50: Sets up loop to calculate waveform points.
60: Calculates I waveform points.
70: Calculates Q waveform points.
80: End of loop.
160 and 210: The I and Q waveform files have the same name
90 to 300: See the table on page 309 for program comments.
