System Overview
Control (PC) System
The commands for each measuring instrument and spinstand all come from the PC. The
commands being sent by the PC to each module of the VXI mainframe passes through the
IEEE-1394 interface.The triggers synchronizing with the index signal are generated from
Agilent E5035B Spinstand Interface Module to all modules and instrument. The Agilent
E5037C/D Data Generator Module of the VXI mainframe sends its write data as controlled
by the Write Gate to the head amplifier from Agilent E5035B Spinstand Interface Module.
The same procedure applies for piezo, HLM and head amplifier. The command passes
through the Agilent E5035B Spinstand Interface Module.
The box type measuring instrument (Oscilloscope) is controlled by the PC through GPIB
cable. Also, the trigger to start measurement from Agilent E5035B Spinstand Interface
Module are received to start measurement.
The stages of the spinstand and spindle as controlled by the spinstand controller, this is
controlled by the PC through RS-232C.
NOTE If your E5023A has Windows 95 operating system, you must turn off the power
management mode to avoid performance (speed) deterioration. For Windows 2000
operating system shipped with the latest version of the E5023A, you don’t need to care the
power management mode because Windows 2000 does not have such mode.
Software
The PC of Agilent E5023A uses an English version of the Windows 2000. Windows
98, Windows Me, Windows NT, Windows XP and other language version of
Windows 2000 are not supported by the system.
The following items have been installed at the factory before shipment.
• Agilent E5023A Measurement Library
• Agilent I / O Library
• Agilent VEE
• Agilent E5023A Test Environment (VEE-based graphical operating program)
• Sample Program (Visual Basic)
• Adobe Acrobat Reader
Agilent E5023A Measurement Library
The Agilent E5023A Measurement Library is a dynamic link library designed to facilitate
measurement programming. This creates an environment that makes the Agilent E5023A
into an integrated system rather than a rack-and-stack set of instruments, which allows the
instruments to perform at a higher level as a system.
The configuration information for head amplifiers and HGA cassettes is stored in the
directory “c:\Program Files\Agilent\e5022\config” as XML files (or “c:\Program
Files\Agilent\e5022\bin” as DLL files).
Agilent I/O Library
Agilent I/O library is a general I/O library to control the instrument. This includes Agilent
VISA library. It is not necessary to care about this library because the Agilent E5023A
