Outputs trace data to a file in either binary or ASCII text. The ASCII text file can be loaded directly into Excel, the binary format is for users who wish to write their own data analysis programs.
1. Output is in rows, each row corresponding to one pixel on the display x axis.
2. Each trace is output in a separate column(s).
3. Each Doppler spectrum is output in 256 columns (one column for each frequency)
4. Warning: Doppler spectrums will produce very large text files!
5. If 'no selection' is chosen, then data from left to right of the active view is used (even if the trace ends part way through).
1. Every point (within selection if applicable) is output irrespective of the x axis scale.
2. If a trace is not in the selection (if applicable) then it will not be output.
3. Each complete trace is output one after the other.
4. Data is always output as 'raw' values.
5. File Format: [HEADER] DATA [HEADER] DATA ..... [HEADER] DATA
6. HEADER FORMAT (total 128 bytes):
Table 7-3. Export data Header Format
| type | bytes | description |
|---|---|---|
| long | 4 | no. of x points |
| long | 4 | no. of y points |
| int | 2 | no. of bytes per element |
| int | 2 | '?' (reserved for future versions) |
| double | 8 | x scaling factor |

7. DATA FORMAT For line traces, the data consists of sequential array of elements, the first being the oldest point, the last is the youngest.
For 2D traces, the data is a sequential array of 256 or 64 point arrays.
Each 256/64 point array being one spectrum (0Hz - bandwidth).
