Text (Tab delimited)
Sharing Data With Other Applications
You can save 89600 VSA traces or recordings as a tab delimited ASCII file (*.TXT). You can recall the file into any program/application that supports text files (for example, Microsoft Excel).
For real data, each line in the file contains a single value. For complex data, each line contains two values, with the real part first, followed by a tab and the imaginary part. The number of lines depends on the number of frequency points in the measured data.
If you save the Data Header with the trace (Save > Save Selected trace > Save Options > Save header with data), it appears in the file above the data, with the variable name first, followed by a tab and the variable's value. Also, the channel data sections will be prefixed with the corresponding data header variable (see Data Header Variables for more information).
The NextItemArray data header variable is an important datatype attribute for efficient reading of large CSV and TXT files and is included in saved trace files even if Save header with data is not selected in the Save > Save Selected trace > Save Options dialog.
When a recording is saved as a text file without the data header and there are multiple channels, the channel data is listed in increasing channel number and there are no markers to indicate where one channel's data stops and another channel's data starts. To separate the data for multiple channels, divide the list of data values into as many equal sections as there are channels in the recording. An alternative is to save the recording with the data header, which separates the data for different channels with the appropriate data header variable.
You can generate a signal in Text format using another application and recall the signal as a recording into the 89600 VSA for analysis.
