Description Item
Cyclic commands only—Sets the command frequency. Frequency
The maximum frequency is limited to 20% of the system rate.
Cyclic commands only—Sets the command wave shape. Wave Shape
Monotonic commands only—Sets the end level of the command. Each
channel can have a different end level. End Level Type
The end level value depends on the end level type selection, which may be
Absolute or Relative. Absolute values are relative to zero. Relative values
are relative to the current output.
The end level value can be changed while a test is running, but the end level
type cannot. End Level value
Monotonic commands only—Defines the ramp of the command. The
command ramp can be defined in terms of time or as a ramp rate. The ramp Time/Rate
starts at the current actuator position and ends at the specified end level.
Each channel can have a different time/rate. The time/rate value can be
changed while a test is running, but the end level type cannot.
Specifies a compensator for your command signal. Compensator
Start Action specifies a system action at the beginning of a test. Done Action
specifies a system action at the end of a test. For information about system
actions. Start Action
Done Action
The specified action executes only if a predefined test endpoint is reached,
as defined by a preset cycle count, or the end levels for each monotonic
channel have been reached.
About the Data Acquisition Tab
Use the Data Acquisition tab to configure how data is acquired during your test. The Basic TestWare application
supports four types of data acquisition: timed, peak/valley, running max/min, and level crossing.
Note:
In the Signals Available list, Date is an integer number of days since Jan 0, 1900, Time of Day is a
fraction of a day since midnight. Both signals are float values that can be imported into Microsoft Excel,
formatted as separate date and time columns, and added together to form one date/time column. Both
signal values correspond to time stamps in the station log.
Timed Data Acquisition
Timed data acquisition records the values of selected signals at user-specified time intervals as Time Between
Points or as a frequency (Sample Rate). For example, if you want to acquire data for the selected signals
every second, set the Time Between Points value to 1 second.
