Use of Macros

Overview of Macros

The E4991A is loaded with a macro function. A macro program allows you to

automatically execute a series of multiple commands by performing a single command. A

macro allows you to combine the steps in a complicated procedure into a single step for a

wide variety of applications as well as to control peripheral equipment.

E4991A VBA (Visual BASIC for Application), which is based on Microsoft’s Visual

Basic, is the programming language used to execute macro functions. Macro commands

are written with the Visual Basic Editor (VBE). However, this manual does not explain

issues such as basic E4991A VBA programming, standard control, and functions. For more

details, please refer to the E4991A VBA on-line help. You can also find up-to date

information on VB from a variety of recent books, including the official manual issued by

Microsoft Co., Ltd. Another information source is the Internet, including Microsoft’s web

page at the following URL:
