Creating and Downloading Waveform Files
Programming Examples
As discussed at the beginning of this section, I and Q waveform data is interleaved into one file in
2’s compliment form and a marker file is associated with this I/Q waveform file.
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.
