You can choose the rate at which your aligned CSV data is exported. For example, if you specify 1000 Hz, all data exported is aligned to 1000 Hz.

You can do this in either of these ways:

- [Set the default output rate for subsequent downloads](#DefaultOutputRate).

or

- [Set the output rate for a single download](#SingleOutputRate).

The Output Rate applies to both aligned CSV and X1D files to align all data to this rate.

If you don't set the Output Rate, the data is aligned to the highest capture rate (ie, High g acceleration), so all data aligns to 1600 Hz.

Set the default output rate for subsequent downloads

1. On the **Settings** tab, select the required export options (for example, the location, raw data (CSV), and aligned data (X1D and CSV)).
2. Select **Output Rate** and in the text box, enter a value between 25 and 3200 Hz.
  The specified output rate is applied to all trials subsequently downloaded, unless you change the settings, either on the **Settings** tab again or via **Edit & download** (see [Set the output rate for a single download](#SingleOutputRate)).

Set the output rate for a single download

1. On the **Process** tab, select the **Edit & download** option for the required trial.  
The **Preview** tab is displayed, showing the currently specified options for **Aligned Outputs**:
  - If you haven't set the default output rate (see [Set the default output rate for subsequent downloads](#DefaultOutputRate)), the Aligned Output options are not selected and the Output Rate is blank.
  - If you have set the default output rate, the values you selected populate the Aligned Outputs options and you can choose to either leave them as they are or change them.
2. Set the required export options (for example, specify the required **Save to** location, raw data (**CSV**), and aligned data (**X1D** and **CSV**)).
3. Select **Output Rate** and in the text box, enter a value between 25 and 3200 Hz.
4. Click **Download** to apply the specified output rate to the selected trial.
