1. Installation
1.1 Hardware Installation
The Agilent E4411B spectrum analyzer is rack mounted in a system
cabinet at the factory. The Agilent E4411B measurement cable is
wrapped with the pulse generator (PG) cables and connected to the
Agilent E4411B input port. After installing the Agilent 4072A,
connect the Agilent E4411B measurement cable to an HF port.
Figure 1-1 shows two different Agilent E4411B rack mount
configurations. If the system includes three or more PG units,
the Agilent E4411B is rack mounted in the system controller
position. If the system contains one or two PG units, the Agilent
E4411B is rack mounted it the position of PG3 through PG5.

1.2 Software Installation
1.2.1 Installing the Spectrum Analyzer Control Software
1) Before installing the software, verify:
• Agilent 4070 system software revision B.02.00 or later is
installed.
- 4 -
• More than 5 Mbytes of disk space is available in the /opt
directory.
2) Load the spectrum analyzer control software.
a. Insert the CD-ROM into the drive, and wait until the
indicator stops flashing.
b. Log in as superuser, and open a dtterm window.
c. Mount the CD-ROM on the /SD_CDROM directory with the
command:
# /sbin/mount /dev/dsk/c0t2d0 /SD_CDROM
Here, it is assumed that the SCSI address of the CD-ROM
drive is 2. If it is not, use the proper special device
file expression, instead of the /dev/dsk/c0t2d0 file.
d. Start the SD install utility with the command:
# /usr/sbin/swinstall
The SD Install – Software Selection window and the Specify
Source window will appear.
e. Select “Local Directory” as the Source Depot Type.
f. Type “/SD_CDROM/HP4070_E4411BDRV_X_01_20.DEPOT;1” as the
Source Depot Path and click OK.
g. Select HP4070_E4411BDVR, and choose “Action:Install
(analysis)”. The Install Analysis window will appear and
the analysis will start.
When the HP4070_E4411BDVR is chosen, an error window will
appears to warn you to verify the items in Step 1 above.
h. When the analysis is complete, click OK to start loading
the software.
i. After loading, click Logfile, and check that there are no
errors in the logfile.
j. Exit the SD install utility.
k. Unmount the CD-ROM from the /SD_CDROM directory with the
command:
# /sbin/umount /SD_CDROM
l. Remove the CD-ROM from the drive.
3) Customize the software.
a. Set up the spectrum analyzer GPIB address file with the
command:
# /opt/ringosc/setup_e4411b_hpib
This script requires you to enter the GPIB address of the
Agilent E4411B. The default GPIB address of the spectrum
analyzer is 718.
The script creates the /opt/ringosc/config file, which is
referred to by the start program calibration script.
b. Edit each user’s profile to change the PCS_ADDON_TIMEOUT
value.
Add the following line in the $HOME/.dtprofile.
export PCS_ADDON_TIMEOUT=60
If the DTSOURCEPROFILE parameter in .dtprofile is defined
as true, add the above line to the user’s .profile or
.login, depending on the shell type of the user.
Note that it must be set to 60. Otherwise, the
/opt/hp4070/addon/start script does not run correctly.
If you load the spectrum analyzer control software before
installing Agilent SPECS, simply re-install the spectrum
analyzer control software
4) Verify the software installation.
a. Start the TIS server with the command:
# /opt/hp4070/bin/hp4070 –start
- 5 -
When the TIS server starts, the /opt/hp4070/addon/start
program is executed. The /opt/hp4070/addon/start program
verifies the existence of the Agilent E4411B, and then
calibrates it. The start log is recorded in the
/opt/ringosc/syslogE4411BDVR file.
b. Check that there are no errors in the
/opt/ringosc/syslogE4411BDVR file.

1.2.2 Further Customization Required for the Agilent SPECS User
1) Create a framework using the Plug Framework (RO_PLUG.fwk) and
the standard framework. If you don't use the standard
framework, INIT_SPEANA must be manually added to your
framework after TESTER_START.
1) Configuration file can be found in the /opt/SPECS/usr/fwk
directory with the name consists of framework name followed
by a suffix (.cf).) The GPIB address is written in the
configuration file with “SPANA_ADDR” parameter.
2) The created framework retrieves the Agilent E4411B and GPIB
addresses from a framework configuration file. (The framework
configuration file can be found in the /opt/SPECS/usr/fwk
directory. The filename consists of a framework name followed
by an extension (.cf). The GPIB address is written in the
configuration file with the “SPANA_ADDR” parameter.) Set the
correct GPIB address in the framework configuration file.
The Agilent E4411B drivers can be called from any algorithm, just
like TIS commands. The drivers cannot be called from a test plan.
1.2.3 Software Installation Details
The software installation consists of:
If Agilent SPECS is installed:
a. Fileset E4411BDVR is loaded on the system. The fileset
E4411BDVR includes the following files:

c. (For BASIC ALGTYPE only) BASIC.make is performed to
integrate the drivers, which are included in the
SpDVRe4411_01.20.usrlib, into the BASIC interpreter.
d. (For C ALGTYPE only) The shared library name
(/opt/ringosc/libdvre4411b.sl) is added to the CUSRLIB
parameter in the sysconf file, and the TEMPLATE.mak file
(/opt/SPECS/usr/etc/TEMPLATE.mak) is modified to
incorporate the shared libraries.
e. The /etc/opt/hp4070/modelname file is read to find out the
tester type.
f. The INIT_SPEANA algorithm is merged into the tester
algorithm library.
