interface of the Agilent E4991A. For more basic information on the COM interface,
refer to Chapter 18, “COM Interface Reference.”
Chapter 15, “Controlling Peripherals”
This chapter explains how to control peripherals connected to the Agilent E4991A by
using the software (VISA) installed in the instrument.
Chapter 16, “Application Programs”
This chapter gives measurement examples (sample programs) using the HTBasic
program and the instrument’s macro program (E4991A VBA).
Chapter 17, “GPIB Command Reference”
This chapter provides the GPIB command reference of the Agilent E4991A. The
command references are written in abbreviated form and listed in alphabetic order.
Chapter 18, “COM Interface Reference”
This chapter gives COM interface references of the Agilent E4991A classified
according to object.
Appendix A, “Manual Changes”
This appendix contains the information required to adapt this manual to versions or
configurations of the Agilent E4991A manufactured earlier than the current printing
date of this manual. The information contained elsewhere in this manual applies
directly to E4991A units bearing the serial number printed on this manual’s title
page.
Appendix B, “GPIB Status Report System”
This appendix describes the status report system in the Agilent E4991A GPIB
system.
Appendix C, “GPIB Command List By Function”
This appendix lists the Agilent E4991A GPIB commands according to function.
Appendix D, “Table of corresponding 4291B vs. E4991A GPIB commands”
This appendix lists each Agilent E4991A GPIB command along with its
corresponding Agilent 4291B GPIB command. Note that the simple commands
prepared for the 4291B do not have equivalent E4991A commands.
Appendix E, “Complex Operation Programs”
This appendix shows sample programs for implementing complex operations in
Visual Basic and HTBasic.
