5.7.4.5 How to Manually Create a Waveform Using Tag File Format
As described in Chapter 5.7.2.1, "Waveform Files Sources", on page 297, you can
generate waveform files internally, with the built-in function, and externally. For descrip-
tion on how to generate waveform files internally, see Chapter 5.7.4.2, "How to Create
Waveform Files with the Built-In Generate Waveform File Function", on page 313. This
section provides an example on how to create a waveform externally. The waveform
file is created manually; the tag-oriented file format is used.
The provided example uses a sine function in the I channel and a cosine function in the
Q channel, each with 20 points. The example uses a short program written in the pro-
gramming language C to calculate the sine and cosine values (see Example "C-pro-
gram for creating a waveform file" on page 321). They are saved in the file SICO.txt.
The decimal values in SICO.txt are normalized such that they are between –1.0 and
