Setting Up the HDLM Functions

The table below summarizes the functions that can be set in HDLM. For

details about each function, see

Each function has a default value and a recommended value. If the Options

window of the HDLM GUI or no function is set by the HDLM command's set

operation, the default value is applied for each function. The recommended

values are used as the guideline values when functions are configured.
