Configuring RMS Channels and Mean Channels

Add a channel that applies RMS averaging or mean averaging to the data in an existing hardware channel. The RMS or Mean channel produces a new value based on averaging performed on the data in a channel in the system.

  1. On the Channel Specification toolbar, select Add channel » Calculation » RMS or Mean, depending on the type of averaging you wish to perform.
    FlexLogger opens a configuration dialog.
  2. Click Data source. Select the channel from which you want the RMS calculation or mean calculation performed.

    If no channels appear in the selector, ensure that you have configured channels in your Channel Specification.

  3. Optional: Update the Name and specify a Description for the calculated channel.
  4. Select from the following Scope of calculation options.
    OptionDescription
    Fixed size blocks Perform the calculation for a subset of channel data based on an interval of time in seconds. Specify the interval of time in Requested block size.
    All channel data Perform the calculation using all the data you collected for the channel since starting the test. To use all the data you collected for the channel since opening the project, uncheck Reset when test starts.
    After you configure the calculated channel, you can see the live value reflecting the averaging you applied to your data. You can use the RMS calculated channel or mean calculated channel like any other channel defined in the Channel Specification.
  5. Click Done.
    FlexLogger adds the calculated channel at the top of the Channel Specification.
Note FlexLogger logs data from calculated channels along with all other channels configured in your Channel Specification. For more information on logging data, refer to Defining Your Test Configuration.
