Configuring: Wave Generator

Generate a dataset with a defined number of fields, each containing data that will conform to a selected wave form. Also configure the amplitude, period and number of rows each dataset will have. Each wave configured represents a generated field.

Worked example: Wave Generator

Steps to configure

Wave types: Select the wave form you would like generated by the data.
Number of rows: Define the size of the wave generated in terms of row numbers (index based) or time.
Configure the wave properties: Configure the amplitude and period of the waves. Each type of wave form and each additional field of the same wave form needs to be configured in terms of field name, amplitude and period.
Execute: A dataset of fields is generated, the values of which take the shape of the wave form specified.

Step 1: Wave types

Select the wave form you would like generated by the data.

Wave shapes are graphically depicted next to each wave form.
Select as many wave forms as required by clicking in the relevant checkboxes.
Default: no wave form is selected.
Minimum configuration: at least 1 wave form is required. Each wave form represents a field to be generated in the dataset.

Step 2: Number of rows

Define the size of the wave generated in terms of row numbers (index based) or time.

Default: Index based is selected with one row entered.
Minimum configuration: value limits need to be defined for each required field.

Index based:

Define the number of rows which will influence the size of the wave generated.
The number of rows entered must be > 1.

Time based:

Define the time window for data values, which will influence the size of the wave generated.
There are 3 different ways to define the window start and end values - select the appropriate radio button.
Start + End:
- The duration of the interval selected will be shown in the duration window.
- The end date of the interval can never be before the start date.
Start + Duration:
- Set the duration of the interval selected in the duration window.
- The end date of the interval will change automatically.
Duration + End:
- Set the duration of the interval selected in the duration window.
- The end date of the interval will remains constant as selected from the calendar.
- The duration of the data window must be > 0 seconds.
The sampling period entered must be > 1.
The number of rows that will be generated is a calculation based on the duration divided by the sampling period.

Step 3: Configure the wave properties

Configure the amplitude and period of each wave to be generated.

Each type of wave form added and each wave of the same form added generates a field in the created dataset.
Each field needs to be configured individually in terms of field name, amplitude and period.
Field name: Specify the name of the field that will be generated.
- No spaces between words are accepted.
Amplitude: Define the required amplitude for each wave.
- This amplitude does not need to be confined to the number of rows in the dataset. An amplitude of greater than the number of rows generated will mean that the complete wave form will not be seen.
Period: Define the length of the wave.
- Index based: The period of the wave is defined in terms of number of rows.
- Time based: The period of the wave is defined in terms of a duration.
Default: All values are left empty.
Minimum configuration: It is necessary to add at least one set of properties for each wave type selected.

Step 4: Execution

A dataset of fields is generated, the values of which take the shape of the wave form specified.
