Creating and Downloading E443xB Waveform Data Using HP Basic for UNIX
On the documentation CD, this programming example's name is "e443xb_hpbasicUx2.txt."
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.
