Getting Started
This chapter provides information to help get you started so that your local oscillator source is
serviced properly.
This chapter answers the questions \What Is Servicing?" and \When Is Servicing Needed?". It
then describes the procedures used to return your local oscillator source to Hewlett-Packard for
servicing.
Getting Started 1-1
What Is Servicing?
Servicing includes testing, adjusting, calibrating, troubleshooting, and repairing.
There are dierent categories of testing available. These categories are module veri cation
tests, system veri cation of operation tests, and system performance tests.
Module Module veri cation tests are used to test modules so that when assembled
Veri cation Tests into a system, the system meets the system's speci cations. These sets of
tests are used during servicing.
System System veri cation of operation tests are used to verify the proper
Veri cation of operation of an instrument and to verify that the instrument meets
Operation Tests approximately 80% of its measurement related speci cations. These sets of
tests are subsets of system performance tests.
System System performance tests are used to verify the proper operation of a
Performance complete modular measurement system (MMS) to full system speci cations.
Tests
This service guide provides information related to testing, adjusting, calibrating,
troubleshooting, and repairing your local oscillator source; it also provides information on
module veri cation tests. These sets of tests are used during servicing.
For information related to system veri cation of operation tests, refer to the HP 70000 Modular
Spectrum Analyzer Installation and Veri cation Manual, and for information related to
system performance tests, refer to the documentation for HP 11990A system performance test
software.
When Is Servicing Needed?
Servicing is needed:
if error messages are displayed on your HP 70000 Series display
if an ERROR LED or FAULT LED is on
to perform repairs or adjustments or both
to verify the correct operation of your local oscillator source
or, if applicable, when upgrading rmware
If you determine that your local oscillator source needs servicing, you can perform
the servicing yourself using the information in this manual or, you can return your
local oscillator source to a Hewlett-Packard service center.
1-2 Getting Started
If You Want Hewlett-Packard to Service Your
Local Oscillator Source
Before calling Hewlett-Packard or returning your local oscillator source for service, please read
your warranty information. Warranty information is printed at the front of this service guide.
In any correspondence or telephone conversations, refer to the local oscillator source by
its full model number and full serial number. With this information, the Hewlett-Packard
representative can determine whether your unit is still within its warranty period.
Determining Your Local Oscillator Source's Serial Number
When a module is manufactured by Hewlett-Packard, it is given a unique serial number. This
serial number is attached to a label on the front frame or front panel of the module. A serial
number label is in two parts. (Refer to Figure 1-1.) The rst part makes up the serial number
pre x and consists of four digits and a letter. The second part makes up the serial number
sux and consists of the last ve digits on the serial number label. The serial number pre x is
the same for all identical modules; it only changes when a change in the electrical or physical
functionality is made. The serial number sux, however, changes sequentially and is dierent
for each module.

Returning Your Local Oscillator Source for Service
Hewlett-Packard has sales and service oces around the world to provide complete support
for your local oscillator source. To obtain servicing information or to order replacement parts,
contact the nearest Hewlett-Packard sales and service oce listed in Table 1-1.
Use the following procedure to return your local oscillator source to Hewlett-Packard for
service:
1. Fill out a service tag (available at the end of this service guide) and attach it to the
instrument. Please be as speci c as possible about the nature of the problem. Send a copy
of any or all of the following information:
any error messages that appeared on the HP 70000 Series display
a completed Performance Test record
any other speci c data on the performance of the local oscillator source
CAUTION Damage can result if the original packaging materials are not used. Packaging
materials should be anti-static and should cushion the local oscillator source on
all sides.
Never use styrene pellets in any shape as packaging materials. They do not
adequately cushion the instrument or prevent it from moving in the shipping
container. Styrene pellets can also cause equipment damage by generating
static electricity or by lodging in fan motors.
2. Place the local oscillator source in its original packaging materials.
If the original packaging materials are not available, you can contact a Hewlett-Packard
sales and service oce to obtain information on packaging materials or you may use an
alternative packing material referred to as \bubble-pack". One of the companies that makes
bubble-pack is Sealed Air Corporation of Hayward, California, 94545.
3. Surround the local oscillator source with at least 3 to 4 inches of its original packing material
or bubble-pack to prevent the local oscillator source from moving in its shipping container.
4. Place the local oscillator source, after wrapping it with packing material, in its original
shipping container or a strong shipping container that is made of double-walled corrugated
cardboard with 159 kg (350 lb) bursting strength.
The shipping container must be both large enough and strong enough to accommodate your
local oscillator source and allow at least 3 to 4 inches on all sides for packing material.
5. Seal the shipping container securely with strong nylon adhesive tape.
6. Mark the shipping container \FRAGILE, HANDLE WITH CARE" to help ensure careful
handling.
7. Retain copies of all shipping papers.

Series 200/300 controllers. Minimum RAM requirement is 2.5 megabytes.
HP 9816 HP 9920 (with HP 35721A monitor)
HP 9836 HP 9000 Series 300 controller
When using an HP 9000 Series 300 controller, a medium-resolution monitor and either an
HP 98203C or an HP 46020A keyboard are required. A high-resolution monitor will preclude
printing graphical test results. Due to the various keyboards supported, some minor text
dierences appear in the menus and softkeys displayed on-screen. (Refer to \Alternate Key
Labels" for an explanation of keyboard dierences.)
Alternate Key Labels
For simplicity in this document, we assume that you are using an HP 9000 Series 200 controller
keyboard. Refer to the list below if your keyboard key labels do not match the ones used in
text.

CS80* GRAPH IO MS
DISKy GRAPHX KBD PDEVz
*Optional { supports Winchester disk drives.
yOptional { supports micro
oppies and older Winchester disk drives.
zOptional { provides debugging features for program development.
In a shared resource management (SRM) environment, the following BIN les are also required:
DCOMM
SRM
Note If you have set up some RAM memory for speci c usage, be aware that this
program uses RAM memory Volume \:MEMORY, 0, 15". Move any information
stored at this Volume to another location before running Module Veri cation
Software.

Printer Compatibility
Module Veri cation Software supports any HP-IB printer; however, many of the printed test
results require a graphics printer. Graphical test results are not output to a non-graphics
printer.

Con guring the Hardware
1. Connect the HP 70000 Series modular spectrum analyzer system to the computer port
determined by the following criteria:
For computers with an HP 98624A HP-IB interface, connect your spectrum analyzer to the
port labeled HP-IB SELECT CODE 8. Check that the address switch on the HP 98624A
HP-IB interface board assembly matches the HP-IB controller device address. If needed,
refer to the HP 9000 Series 200/300 controller Peripheral Installation Guide, Volume 1.
For computers without an HP 98624A HP-IB interface, connect the HP 70000 Series
modular spectrum analyzer system to the port labeled HP-IB SELECT CODE 7.
2. Connect the HP-IB cables from the test equipment to the computer's HP-IB SELECT CODE 7
port.
3. Use a 0.5 meter HP-IB cable (HP 10833D BNC 0.5 meter HP-IB cable, or similar cable) to
connect the external disk drive's HP-IB to the HP-IB SELECT CODE 7 port.
Note Occasionally disk drives exhibit unpredictable behavior when sharing the
HP-IB with instruments. If you nd this occurring, connect the disk drive to a
separate HP-IB interface.
4. Set the external test equipment and the HP 70000 Series modular spectrum analyzer system
line switches to ON. Allow the equipment to warm up as speci ed for the veri cation tests
or adjustment procedures.
5. Turn the disk drive (if used) and computer ON.

Installing Module Veri cation Software
Use the following steps to get the program loaded and running. Later sections of this chapter
contain more speci c program-operation information.
Two assumptions are made with the Module Veri cation Software. One is that you are using
standard HP-IB addresses for the active devices of the microwave test station. The second
is that all passive devices for the microwave test station are available. If either of these
assumptions is inaccurate, you are prompted for data during program execution.
1. View the version number of the software program after loading the rst program disk.
Look in the right-hand side of the initial display. Speci c numbers vary, but the version
number looks like this: Rev. A.02.00
2. Locate the program part number printed on the disk labels.
3. Load HP BASIC 4.0 or later, with the appropriate binaries, into an HP 9000 Series 200/300
controller. If necessary, refer to an HP BASIC reference manual.
CAUTION Make backup copies of all write-protected disks. If the program data on an
individual disk should become altered, it cannot be ordered separately. The
entire set of disks must be ordered to replace any single disk.
4. Assign the MSI (mass storage is) to the drive you will use as the default drive. As an
example, assigning the MSI to a disk drive looks like this: MSI ":,700,0"
5. Insert Executive Disk 1 into the assigned default drive. Type the following command line:
LOAD "MOD_VERF",1
6. Press 4EXECUTE5. The software version number appears in the screen that is next displayed.
7. Follow the on-screen prompts and load Executive Disk 2. Press 4CONTINUE5. Loading
Executive Disk 2 may require up to two minutes.
Note Be sure the Executive Disk 3 you load is the disk that belongs with the module
you wish to test.
8. Replace Executive Disk 2 with Executive Disk 3, then press PROCEED . If the date and time
NNNNNNNNNNNNNNNNNNNNNNN
prompt appears, enter the date and time in the speci ed format. (This message appears
only if date and time are not current.)
9. If you are using your module's software for the rst time, a message appears stating that
mass storage data is needed. Press PROCEED and follow the on-screen prompts to create a
NNNNNNNNNNNNNNNNNNNNNNN
mass storage data le. Once mass storage data is stored, this message will not reappear.
10. An error message may be displayed at this point. If the DUT (device under test) does not
match the module listed in the HP-MSIB Address Map, or if the software you are using
belongs to another module of your system, refer to \Error Messages" at the end of this
chapter to determine a course of action.
11. Load the Operating Disk as directed. The Operating Disk probably needs to remain in the
drive speci ed as the MSI default drive. Load the Driver Disks into the drive speci ed
on-screen.
12. Load all Driver Disks. Insert each Driver Disk and press PROCEED . This process may
NNNNNNNNNNNNNNNNNNNNNNN
require up to six minutes.
13. If you have not entered serial numbers for passive devices that require calibration data for
test purposes, on-screen prompts request the data now. Enter the data via the Calibration
Module Veri cation Software 2-5
Data screen. Press CREATE to access this screen. For a detailed explanation of entering
NNNNNNNNNNNNNNNNNNNN
calibration data, refer to \Edit Calibration Data" under \Menus" in this chapter. Enter
the serial number for each device speci ed, or bypass the device to continue if it is not
used now. After entering and storing data for passive devices, this prompt screen will not
reappear.
Note In the future, you can access calibration data stored on Operating Disks, rather
than enter the data for passive devices of a given serial number each time you
