  • Name: Enter a name for the channel. The name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<', '>').
  • Collect: If selected, the channel data is written to the SIE data file during a test run.
  • Description: Enter an optional detailed description of the computed channel.
  • Measurand: Enter the quantity being measured or the type of measurement associated with the computed channel.
  • Units: Enter the physical units of measurement for the computed channel.
  • Range min and Range max: Enter the expected extreme values of the computed channel output.

All input channels to a single Signal Calculator channel must have the same sample rate, which also determines the computed channel sample rate.

Double-click or drag and drop a channel or operator to add it to the expression. Alternatively, build the expression using keyboard entry. All operators and referenced input channels are case sensitive.

NOTE
If using drag and drop to select channels and functions, the item is dropped at the current position of the cursor.
