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.
- SM: For Smart modules connected to a channel, a status is displayed. 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.
- 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.
- Sample rate: Select the desired channel sample rate. If the sample rate changes, all dependent computed channels and DataModes™ are changed automatically.
- Measurand: Enter an optional measurement type.
- Input mode: Select the digital input mode from the options presented. In the channel edit dialog, a wiring diagram for the selected input mode is available for reference.
- 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.
- 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.
- 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.
- Network node: A CPU serial number shows for a module or camera channel's network node.
- Custom column information: For each column to be used, enter a unique name for the column header. Select either the “Text” or the “Numeric” sorting option.
- 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. For EBRG and EHLS channels, they are used to set the programmable gain and D/A offset to maximize the resolution of the data.
- 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.
