Can I modify an existing mask or create a new mask?

With software revision A. 02. 00 and above you can create a new mask or copy and edit any of the standard masks that are available on the instrument hard disk. Mask files are ASCII text files that can be edited or created on any PC using a text editor such as Microsoft Notepad.You can copy standard mask files from the instrument hard disk using the floppy disk drive (A:) or from any mapped drive connected to the instrument LAN port. Once a custom mask has been created or edited, you can dopy it back to the instrument hard disk then open it, or open it from the floppy disk drive (A:) or from a mapped drive.
