System preferences apply to all users of the system. Whenever possible, the changes take effect immediately for the user making the changes. Other users already logged in at the time the change need to log out and log back in for the settings to take effect.
Specify the Sample rate domain as either Decimal or Classic. The sample rate domain controls the sample rates and associated digital filter types and frequencies when configuring input channels. This setting determines the sample rate domain for new test setups, which you cannot change. The default setting is Decimal, which includes typical sample rates of 5000, 2500, 1000, and 500 Hz. In the HBM Classic domain, typical nominal sample rates include 4800, 2400, 1200, and 600 Hz.
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 8388608/8388608.
NOTE
Select the applicable Aux connector mode - VBM, Sync Clock or ECM - to specify what type of hardware is connected to the CX23-R auxiliary port.
Select the default Bridge shunt polarities for MX1615B-R bridge channels when installing shunts with a test run in progress or when using the shunt resistor sensor scaling mode. Select either Up scale for positive shunt polarity or Down scale for negative shunt polarity.
NOTE
You cannot change the default polarity for the 3-wire quarter bridge configurations.
In the Exception Handling section, set the Max number of test restarts on error resets. If a test unexpectedly ends or the CX23-R loses power during a test run, the system attempts to rerun the test after a restart. Enter a value between 0 and 5. If the value is zero, the system does not attempt a test restart.

Select the Authentication required option to display the login dialog at the start of a session. If deselected, the default user is automatically logged in. This option is only applicable if the default user credentials have not been changed from the factory settings.
Specify a Minimum password length for new users and future password changes. Existing passwords for current users do not need to conform to this length.
Select the Default language for each new user. Once logged in, users may change the interface language at any time.
Select the Allow test run if warnings exist in setup option to start a test run when warnings are present. If deselected, test runs do not start until warnings are resolved.
Select the Display test duration prompt option to ask for a test duration at the start of each test run. If specified, the test run automatically stops when the duration time elapses.
Select the Use system defined sensor scaling filters option to use the system defined sensor scaling sample rates and digital filters for zeroing and experimental sensor scaling for MX1601B-R and MX1615B-R channels. The sample rates and filters are a function of the sample rate domain as defined in the table below. If deselected, the system uses user-defined sample rates and digital filters.
Sample rate domain | Sample rate | Filter type | Filter frequency |
---|---|---|---|
Decimal | 100 Hz | FIR Butterworth | 15 Hz |
Classic | 50 Hz | IIR Butterworth | 10 Hz |
