Input channel generic parameters
Many parameters are common across all channels and are displayed in the All channels tab:
- Connection: A unique hardware identifier created by the system.
- TEDS: For MX module channels with TEDS sensors connected, an icon is displayed with the TEDS status. Not in edit dialog. See Configuring TEDS sensors for more information.
- SDB: For MX module channels with HBM sensor databases applied, an icon is displayed with the SDB status. Not in edit dialog.
- Reading: Current value of the channel. Show the readings by selecting the desired channels and clicking
Live update. Not in edit dialog.
- Units: For most channel types, the user can enter the physical units as desired; however, for some channel types (i.e., most temperature channels, and any bridge channel that uses the Strain gage scaling mode), the user can only select an option provided in the drop down list box presented.
- Name: The channel name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<' and '>'). Invalid channel names are 'true' and 'false' (case sensitive).
- Description: Enter an optional detailed description of the channel.
- Measurand: Enter an optional measurement type.
- Data type: The format of the channel data output (read only).
- Collect: Select the Collect checkbox to write the channel data to the SIE data file during a test run.
- Sample rate: Select the desired channel sample rate. If the sample rate changes, all dependent computed channels and DataModes™ are changed automatically.
- Filter type: For applicable channels, select the type of filter for the channel to None, Linear phase (FIR), Butterworth (FIR), Butterworth (IIR) or Bessel (IIR).
- Filter frequency: Set the frequency of the selected filter. The options vary based on the filter type.
- Custom column information: Enter the desired information. The system treats all input as free formatted text. This means it will sort alphabetically, but not alphanumerically (e.g., input values of “1”, “2”, “11”, will be sorted descending as “1”, “11”, “2”). Use leading zeros to realize alphanumeric sorting.
- Range min / Range max: Enter the desired full scale range min and max values in physical (engineering) units. For all channels, they are used as the default min and max bounds for histogram DataModes.
- Alarm min / Alarm max: Enter the desired values for min and/or max alarms as a physical units value or as a % of Range min/max value.
- Warning min / Warning max: Enter the desired values for min and/or max warnings as a physical units value or as a % of Range min/max value.
- Chart type: Set the default chart type for the channel. Not in edit dialog.
- Decimals: Select the default decimal places for channel displays. Use the “Auto” option to apply the settings defined in the User Preferences. See User preferences > General > Decimal point handling for more information.
