How Do I Export the Oscilloscope Data?

To copy the trace data into a CSV file:

  1. Display the softscope
  2. Ensure the channels you want to export are Enabled and Visible
  3. Start the data collection
  4. Wait for the probe data you want to save to be collected
  5. Stop the data collection
  6. Click the Export... button
  7. Select where you want to save the CSV file
  8. Click the Save button

Channels start recording a few cycles after the previous channel, based on resources. To see all channels at same time you need to wait until data is being sent from all channels. If you start the capture at the first cycle the exported data will not line up. The first table below shows aligned data of the channels from starting the program. Note how it takes several cycles for the data to be captured. The second table shows hohis data would appear in a CSV file. Note how the time columns do not match. Waiting for all channels to be recording will eliminate this.

You can now import the data into Microsoft Excel.


  • The Export operation is possible even when acquisition of samples is in progress. But in that case, the latest exported data are the data collected when you have defined the CSV file.


  • The acquisition of samples is limited to 100 s when the cycle time is set to 1000 µs (respectively 50 s with 500 µs, and 25 s with 250 µs)

Each channel takes 2 columns: one for the time and the other for the value. This allows exporting channels with different time-base.

The List separator and the Decimal symbol are hard-coded (they are not bind to the regional settings)

  • List separator is comma (,)
  • Decimal symbol is dot (.)

  • If your regional settings are different, then you have to specify explicitly those two characters in Microsoft Excel to correctly import the CSV file
