Field

Description

Time Unit

Select the time unit that is applicable to the time fields on this tab.

Interval Type

Select an interval type that corresponds with the desired generation of Pulse UDRs.

Fixed - UDRs are generated at a fixed time interval

Linear - UDRs are generated at a linearly increasing or decreasing time interval.

Gaussian - UDRs are generated according to a Gaussian probability distribution.

Poisson - UDRs are generated according to a Poisson process.

Single - A single UDR is generated at workflow start.

Interval

Specify the interval between the pulses according to the Time Unit selected above. 

Interval is available when the selected Interval Type is Fixed.

Start

Specify the start interval between pulses.

Start is available when the selected Interval Type is Linear.

Stop

Specify the final interval between pulses.

Stop is available when the selected Interval Type is Linear.

Rate

Specify the value that is incremented or decremented from the interval when a Pulse UDR is generated. Use a positive value to increment and a negative value to decrement.

Rate is available when the selected Interval Type is Linear.

Central Interval

When the selected Interval Type is Gaussian, enter the median interval between Pulse UDRs in the probability distribution.

When the selected Interval Type is Poisson, enter 1/(expected number of Pulse UDRs per time unit).

Example - Poisson interval type

Expected number of Pulse UDRs is five (5) per second, so 0.2 seconds between UDRs.

Select MILLISECONDS in Time Unit and enter 200 in Central Interval.

Central Interval is available when the selected Interval Type is Gaussian or Poisson.

Width

Enter the standard deviation of the probability distribution. When you use a low value, the intervals tend to be close to the value of the Central Interval. Use a high value to spread the intervals over a wider range.

Width is available when the selected Interval Type is Gaussian.

Field

Description

Random With Range

Select this radio button to populate the Sequence field in the Pulse UDRs with a random integer. The range of the values is specified in the Range fields.

Sequential

Select this radio button to populate the Sequence field in the Pulse UDRs with a value from an infinite sequence starting at 0. The sequence is reset when a workflow is restarted.

Sequential With Range

Select this radio button to populate the Sequence field in the Pulse UDRs with a value from a finite sequence. The range of the values is specified in the Range fields. The sequence is reset when a workflow is restarted or when the end value is reached.

Range

Enter the start and end value of the sequence. You can use negative values but the end value must be greater than the start value.

Random Data

Select this radio button to generate random data in the Data field of the Pulse UDRs. The data is generated when the workflow starts and each UDR will contain the same data.

Size

Enter the size of the random data and select the byte unit from the drop-down list.

Fixed Data

Select this radio button to have fixed data in each PulseUDR. Enter the data in the text area that is to be populated in the Data field of the Pulse UDRs.
