Pattern Header

The second section following the file header is Pattern Header. It contains the order information for the pattern parameters. The parameter items are located in the parameter table area of the Pattern Library form's Pattern Details. The CSV file's Pattern Header section must begin with the keyword PATTERN_HEADER_BEGIN, and end with the keyword PATTERN_HEADER_END. The pattern header items include the following:

When you import an older CSV file, all of the Hop pattern properties will be set to their default values. There is no effect on existing signals. When you export, the Hop properties are placed after the Antenna Radiation Properties in the CSV file.

As shown in this example of a CSV file's partial ClosedPattern Header section, the header items are listed in a single row between the keywords with one header per column.

The pattern header items are organized into five main groups. Each group contains sub-groups of related parameters as shown in the following figure. While you may reorganize the header items, Keysight recommends that you not do so, since the Export Pattern command uses the order shown here. If you eliminate pattern header items from an imported file, Pulse Building will use default values. See Pattern Items for details.

An easy way to prepare a CSV file that lists the pattern header items in the recommended order, is to create a new pattern in Pulse Building using several pattern parameters, then export the pattern using the menu item (File > Export Pattern).
