The S240 RTSA application allows you to capture and export signal data to a CSV file for playback or further processing by another application. All recorded data is stored on the PC that is hosting the S240 RTSA application.
By default, the system stores the file (csv-0000.csv) in the pyrf/RTSA/Scripts/dist directory.
- Click the Save Data button to access the Save Data soft panel.
- Optionally, enter a comment in the Comments box. The text you enter is added to the top of the saved .csv file.
- Click folder icon to confirm the storage location or specify a path, then click on Save Data. The RTSA application begins saving signal data to the CSV file.
- If you do not want to use the default name for the CSV file, click on Save Data As and specify a file name in the CSV File window, then click Save. The RTSA application begins writing the signal data to the CSV file.
- To stop saving signal data to the CSV file, click Stop Saving. The RTSA application stops writing the signal data to the CSV file.
The stored CSV file contains the following information about the captured signal:
| Parameter | Description |
| mode | The RFE mode of the device during signal capture. Possible values are: ZIF (100 MHz instantaneous bandwidth) SH (40 MHz instantaneous bandwidth) SHN (10 MHz instantaneous bandwidth HDR (100 kHz instantaneous bandwidth) DD (Baseband, 0-50 MHz instantaneous bandwidth; no tuning) |
| fstart | The start of the frequency range (Hz) |
| fstop | The end of the frequency range (Hz) |
| size | Number of data points (power values) captured for the signal in the CSV file |
| timestamp | ISO time-stamp representing time at which the data was displayed in the S240 GUI |
| <data> | A series of integers representing the power value of the captured signal for each sample. The number of data samples corresponds to the value specified in the size parameter. |
