System configuration > Preferences
System preferences apply to all users of the system. Changes to some of these preferences require a system reboot. For changes that do not require a system reboot, the changes take effect immediately for the user making the changes. Other users already logged in at the time of the change need to log out and log back in for the settings to take effect.
NOTE
The nominal Classic domain sample rates are used for convenience. The actual sample rates are approximately 260 ppm greater than the nominal sample rates. To find the exact sample rate, multiply the nominal sample rate by 8388608/8386425.
NOTE
SomatXR MX modules do not support the Binary domain. Legacy eDAQ layers do not support the Classic domain.
NOTE
Modules named outside of the web interface that do not conform to the naming rules are automatically renamed. In the case of illegal characters, the characters are replaced with underscores. In the case of a name that matches the internal module identifier, the name is prefaced with an underscore.
NOTE
Power failures and user-initiated reboots are not error resets. The system always attempts to restart an interrupted test when either of these events occurs. The user is provided an opportunity to abort the test restart, but only while the restart is in progress – which could be a very short time period.
Custom column names
Four user supplied customizable parameters can be used for a setup's source channel configuration. These can be used for any desired purpose and can contain any desired values. Those with a blank value will not show in the single channel editor.
When a User info name is entered and saved, custom column names are automatically filled in a new Test setup.
Custom column name type
For the Type, select Text or Numeric for sorting channel rows. Text is the default and will allow sorting of rows by the text string entered for the Custom column name. Numeric may be selected and will allow sorting of the rows numerically by the content entered for the Custom column name.
In Numeric sorting, strings that are not numbers are ignored in the sorting algorithm, and will be displayed at the top or bottom of the list in an arbitrary order.
Numeric content is simple number strings, such as positive or negative integers and decimals. Fractions, roots and other mathematical symbols, such as an equation, are not supported and will be sorted to the top or bottom of the list in an arbitrary order.
Calibration options
Use channel calibration dates and locks:
Channel calibration locks are used to ensure that channel configuration parameters are not accidentally changed. This is most significant for channels defined using experimental scaling that can be a time consuming and/or technically challenging process. The associated calibration dates provide a means for assessing the need to periodically rerun experimental scaling measurements. Since some users may find the overhead on using this feature annoying and unnecessary, this System preference is available to disable this functionality.
NOTE
When a new SXR setup is created, the setup inherits this option from this System preference and cannot be changed.
Select the checkbox so new test setups use channel calibration date and locks. In Test configuration, Use channel calibration dates and locks shows True. In a new test setup, a calibration date and the Calibration options... button show for a channel in any Edit channel dialog.
If the checkbox is not selected, a new test setup created in Test configuration will not have channel calibration dates and locks enabled. In Test configuration, Use channel calibration dates and locks will show False.
Allow SIE tests to be run with channels that are not calibrated:
The default is to prevent SIE tests from being run with uncalibrated channels. Select this checkbox to enable a SIE test to be run with a uncalibrated channels.This option is applicable to only a limited set of channel types.
Select the Use system defined sensor scaling filters option to use the system defined sample rates and digital filters for zeroing and experimental sensor scaling for applicable channels (e.g., MXB-R module analog channels). The sample rates and filters are a function of the sample rate domain as defined in the table below. If deselected, the user defined sample rates and digital filters for each channel are used.
Sample rate domain | Sample rate | Filter type | Filter frequency |
---|---|---|---|
Decimal | 100 S/s | FIR Butterworth | 15 Hz |
Classic | 50 S/s | IIR Butterworth | 10 Hz |
Binary | 102.4 S/s | FIR Butterworth | 15 Hz |
NOTE
The MX411B-R does not support FIR filters in High speed mode. In this usage case, the above Classic domain settings are also used in the Decimal domain.
