Testing Performance
Testing Performance
To ensure the logic analysis system is operating correctly, you can perform
software tests (self-tests) on the system. Directions for performing the software
tests are given in this chapter.
This chapter normally tells you how to test the performance of the logic analysis
system against the specifications listed in chapter 1. Because there are no
specifications for the 16700A/16701A/16702A, there are no performance
verification tests.
Self-Tests
The self-tests listed in this chapter check the functional operation of the
mainframe and the expansion frame. Self-tests for the optional modules installed
in the frames are listed in the individual module Service Guides.
There are two types of self-tests: self-tests that automatically run at powerup,
and self-tests that you select on the screen. For descriptions of the tests, refer to
chapter 8, "Theory of Operation."
Perform the self-tests as an acceptance test when receiving the logic analysis
system or when the logic analysis system is repaired.
If a test fails, refer to chapter 5, "Troubleshooting."
Test Interval
There is no recommended test interval for the 16700A/16702A mainframes or the
16701A expansion frame. However, each of the supported modules has
performance verification tests and therefore require a periodic verification of
specifications. Refer to the Service Guides of the individual modules for more
information.

Troubleshooting
To run the self-tests
To run the self-tests
Self-tests identify the correct operation of major functional subsystems of the
instrument. You can run all self-tests without accessing the interior of the
instrument. If a self-test fails, refer to the troubleshooting flowcharts to change a
component of the instrument. To run the self-tests:
1 In the System window, select System Admin.
2 Under the Admin tab, select Self-Test. At the Test Query window, select Yes.
You can run the tests individually, or you can run all of the tests by selecting
Test All at the bottom of the Self Test window. Note that if Test All is selected,
tests requiring user action will not be run. For more information, refer to
chapter 8. These procedures instruct you how to perform the tests individually.
3 In the Self Test window, select System CPU Board.
4 Run the Floppy Drive Test.
a In the Self Test: System CPU Board window, select Floppy Drive Test.
b Insert a DOS-formatted floppy disk with 300 KB of available space in the mainframe
floppy disk drive.
c In the Test Query window, select OK.
The Test Query window instructs you to insert the floppy disk into the floppy disk
drive. The other System CPU Board tests require similar user action to successfully
run the test.
5 In the Self Test: System CPU Board window, select Close to close the window.
6 In the Self Test window, select PCI Board. You can run the individual PCI Board
tests individually without any user action.
7 In the Self Test window, select the Master Frame tab. You can run individual
tests on each installed measurement module and emulation module in the
Master Frame.
8 If an expander frame is installed, select the Expander Frame tab in the Self
Test window. Individual tests can be run on each installed measurement module
and emulation module in the Expander Frame.
Refer to chapter 8 for more information on tests that are not executed. The
service manuals for applicable measurement modules will have information on
tests that are not executed.

Reignite: Re-installing the operating system
Reignite: Re-installing the operating system
Read this section carefully before you attempt to re-install the operating system
using this procedure.
CAUTION
Everything on the hard disk drive will be overwritten, including the user
configuration, data files, and license passwords.
A batch process is used to autoload the software and then reboot the instrument.
The batch process waits for only a short timeout period for user interaction to
abort the process. Otherwise, the hard disk drive will be initialized, the operating
system will be uploaded, and the instrument will reboot.
The Reignite process takes approximately one hour depending on the speed of
the attached CD-ROM.
See Also
"To save the license file" in chapter 6 for information on saving the license
password.
To reignite:
1 Set up the instrument.
a Connect the monitor, keyboard, and mouse to their rear panel ports.
b Connect a SCSI CD-ROM drive to the SCSI port on the rear of the instrument.
Ensure the CD-ROM drive is set to a SCSI address in the range 1-5.
c Apply power to the CD-ROM drive.
d Insert the CD-ROM containing the instrument operating system into the CD-ROM
drive.
Allow a couple of minutes for the CD-ROM drive to settle after inserting the media.
e If the LAN cable is connected, disconnect it from the instrument.
2 Connect the power cord to the instrument, then apply power.
3 If needed, initiate the monitor selection mode.
a When the LED on the NUMLOCK key on the keyboard illuminates and remains lit for
approximately two seconds, press the [ TAB ] key. (This happens very soon after
power is applied).

external monitor.
Unlike an external monitor, the LCD display will not light up at all unless the
correct resolution and refresh rate are configured. The correct resolution and
refresh rate are configured when monitor mode "21" is entered.
If the display did not illuminate after the procedure in this section completed,
there is a problem with either the cabling or the display. Remove the front panel
and make sure that all cables are properly seated. If the cables are properly
seated, you should suspect the display.

Troubleshooting
To troubleshoot initialization failures
To troubleshoot initialization failures
By the time the logic analysis system reaches the initialization phase during the
boot process, the core subsystems have been tested and are operating. During
initialization, the system is being configured to run the operating system
software.
A FAIL status during initialization does not necessarily mean there is a serious
problem or catastrophic failure of the hardware. Failures are often generated
because of changes in the configuration of the hardware or of the system.
Occasionally a FAIL status is caused by software file corruption.
If the logic analysis system is part of an equipment pool that is shared among a
number of users, then some of the network-related initializations can result in a
FAIL status as some users utilize the networking capabilities of the instrument.
If a FAIL status is reported during initialization, then most likely the system is still
usable if initialization completes, the entire boot process completes, and the
System window appears. If the boot process halts (with or without an error
message), then a system problem must be corrected before the logic analysis
system is usable.
On the logic analysis system display, the initialization phase of the boot process
looks like this:

Troubleshooting
To troubleshoot initialization failures
HP-UX Startup Process
Result or Cause of Failure
Mount file systems
The most likely cause is a hard disk drive hardware failure
that was not found earlier in the boot process. A secondary
cause of a FAIL status is that the hard disk drive cables are
not properly seated in the disk drive or in the PCI board.
Setting hostname
The most likely cause is a change of network configuration.
Enable auxiliary swap space
This is an unlikely failure.
Start syncer daemon
This is an unlikely failure.
Configure LAN interfaces
The most likely cause is a hardware failure of the CPU board
that was not found earlier in the boot process, or a hardware
failure of the PCI board. If a LAN cable is not connected to
the 10BaseT port, or if a 50-ohm termination is not
connected to the 10Base2 port, a FAIL status may also be
reported.
Start Software Distributor
agent daemon
The most likely cause is a networking or port configuration.
A secondary cause of a FAIL status is corrupted software.
Clean up old log files
This is an unlikely failure.
Start system message logging
daemon
This is an unlikely failure.
Configure Ethernet interfaces
The most likely cause is the networking configuration.
Configure LAN interfaces
More LAN configuration is performed here. The failure
modes are the same as mentioned earlier.
Start NFS core subsystem
This is an unlikely failure.
Start NFS client subsystem
A FAIL status is returned when the instrument is connected
to a LAN, the networking configuration is not correct
(especially the IP address and subnet mask), and/or a remote
workstation that was mounted to the instrument file system
configured as Mount Always is no longer available. The
quickest workaround of a FAIL status is to disconnect the
LAN cable if the instrument will not be networked.
Start Internet services
daemon
The most likely cause is the networking configuration.
Start time synchronization
Always returns N/A because this feature is disabled.
Start print spooler
The most likely cause of failure is a hardware failure of the
CPU parallel port. An N/A status is caused when the print
spooler is disabled.

Replacing Assemblies
This chapter contains the instructions for removing and replacing the assemblies
of the logic analysis system. Also in this chapter are instructions for returning
assemblies.
WARNING
Hazardous voltages exist on the power supply. To avoid electrical shock,
disconnect the power from the instrument before performing the following
procedures. After disconnecting the power, wait at least six minutes for the
capacitors on the power supply board to discharge before servicing the
instrument.
CAUTION
Damage can occur to electronic components if you remove or replace
assemblies when the instrument is on or when the power cable is connected.
Never attempt to remove or install any assembly with the instrument on or with
the power cable connected.
Replacement Strategy
These replacement procedures are organized as though you are disassembling
the complete instrument, from the first assembly to be removed to the last. Some
procedures tell you to remove other assemblies of the instrument, but do not give
complete instructions. In these cases, refer to the procedure for that specific
assembly for the instructions.
CAUTION
Electrostatic discharge can damage electronic components. Use grounded wrist
straps and mats when performing any service to this logic analysis system.

To save the license file
To save the license file
Before doing any major repairs to the instrument, it is recommended that you
back up the license file if possible. You will need a backup copy if you encounter
any problems that require a software Reignite.
The license file has all of the licenses for the toolsets and user registration. If, for
some reason, you lose the license file, you can obtain new license codewords from
the Agilent Technologies Password Center.
To save the license file:
1 Obtain a formatted floppy disk and insert it in the floppy disk drive.
2 In the System window, select File Manager.
3 In the “licensing” subdirectory, copy the license.dat file to the floppy disk.
To recover passwords
The password file /logic/licensing/license.dat file may be lost under any of the
following circumstances:
•
Catastrophic failure of the hard disk drive.
•
Software Reignite.
•
User error.
•
Instrument sent to an Agilent Technologies Service Center with Secure mode enabled.
To avoid losing the license.dat file, back up the file onto a floppy disk and keep
the disk in a safe place. The license.dat file can also be archived in any DOS or
HP-UX environment.
If the license.dat file (which includes the passwords) is lost, any activated
toolsets will become unavailable and the User Registration window will again
become visible. To recover the passwords and re-create a license.dat file, you
must contact the Agilent Technologies Password Center. Provide the instrument
ID number to the Password Center, and they will re-issue your passwords.
An Agilent Technologies Service Center can contact the Agilent Technologies
Password Center after an instrument repair to recover toolset passwords. The
Agilent Technologies Service Center must provide the instrument ID number to
the Agilent Technologies Password Center to recover the toolset passwords.
However, you must contact the Agilent Technologies Password Center to recover
your User Registration password.

procedures, see "16701A Expansion Frame Assembly/Disassembly."
To remove and replace optional modules or filler panels
The procedures for removing and replacing optional modules or filler panels is
the same for the 16700A/16701A/16702A.
1 Remove power from the instrument.
a Exit all logic analysis sessions. In the session manager, select Shutdown.
b At the query, select Powerdown.
c When the "OK to power down" message appears, turn the instrument off.
2 To reconfigure your system later in this procedure, note the configuration of
your system now.
Some modules for the logic analysis system require an operational accuracy
calibration if you move them to a different slot.
3 Starting from the top, loosen the thumb screws on filler panels and cards in the
mainframe or the expansion frame. Starting from the top, pull the cards and
filler panels out.
All multi-card modules will be cabled together. To prevent damage to the cables
and connectors, pull all multi-card modules out together.
4 To replace the modules, reposition all cards and filler panels so that the
endplates overlap properly.
5 Firmly seat the bottom card into the backplane connector of the mainframe.
Keep applying pressure to the center of the card endplate while tightening the
thumb screws finger tight. Repeat for all cards and filler panels in a bottom-totop order.
For correct air circulation, filler panels must be installed in all unused card slots.
Correct air circulation keeps the instrument from overheating. Keep any extra
filler panels for future use.

This chapter contains information for identifying and ordering replaceable parts
for your logic analysis system.
Replaceable parts ordering
Parts listed
To order a part on the list of replaceable parts, quote the Agilent Technologies
part number, indicate the quantity desired, and address the order to the nearest
Agilent Technologies Sales Office.
Parts not listed
To order a part that is not on the list of replaceable parts, include the model
number and serial number of the module, a description of the part (including its
function), and the number of parts required. Address the order to your nearest
Agilent Technologies Sales Office.
Direct mail order system
Within the USA, Agilent Technologies can supply parts through a direct mail
order system. The advantages to the system are direct ordering and shipment
from the Agilent Technologies Part Center. There is no maximum or minimum on
any mail order. (There is a minimum amount for parts ordered through a local
Agilent Technologies Sales Office when the orders require billing and invoicing.)
Transportation costs are prepaid (there is a small handling charge for each order)
and there are no invoices.
In order for Agilent Technologies to provide these advantages, a check or money
order must accompany each order. Mail order forms and specific ordering
information are available through your local Agilent Technologies Sales Office.
Addresses and telephone numbers are located in a separate document at the
back of the Service Guide.
Exchange Assemblies
Some assemblies are part of an exchange program with Agilent Technologies.
The exchange program allows you to exchange a faulty assembly with one that
has been repaired and performance verified by Agilent Technologies.
After you receive the exchange assembly, return the defective assembly to
Agilent Technologies. A United States customer has 30 days to return the
defective assembly. If you do not return the defective assembly within the 30
days, Agilent Technologies will charge you an additional amount. This amount is
the difference in price between a new assembly and that of the exchange
assembly. For orders not originating in the United States, contact your nearest
Agilent Technologies Sales Office for information.

Theory of Operation
This chapter tells the theory of operation for the logic analysis system and
describes the self-tests. The information in this chapter is to help you
understand how the logic analysis system operates and what the self-tests are
testing. This information is not intended for component-level repair.
8-2
Block-Level Theory
The block level theory includes the theory of operation of the 16700-series logic
analysis system in terms of the major subsystems.
The 16700-series logic analysis system
The system level block diagram shown here includes the following subsystems:
•
CPU Board
•
PCI Board
•
Interface Board
•
Measurement Module Backplane
•
Emulation Module Interface
•

Theory of Operation
Subsystem overview theory
Subsystem overview theory
This section discusses the subsystems and the components that make up each
subsystem.
CPU Board
The CPU is a 150 MHz PA-RISC workstation processor. The CPU board, working
with both the PCI board and Interface board, manages the data flow between the
mainframe components and both the measurement modules and emulation
modules.
The CPU is supported by the following components:
Clock Circuitry
A 30 MHz on-board crystal oscillator is on the CPU board. The 30 MHz frequency
is divided by 2, then upconverted to by a PLL clock distribution IC to also create
60 MHz and 150 MHz. The 15 MHz, 30 MHz, and 60 MHz frequencies are utilized
by buses and backplanes. The 150 MHz frequency is utilized by the processor.
8-4
Theory of Operation
Subsystem overview theory
System RAM
A total of 64 MB of system RAM is available in the factory default configuration.
32 MB of base on-board system memory is present, plus a 32 MB proprietary
memory daughter card is added.
I/O
Most of the I/O ports are directly managed by the CPU board. These include the
LAN (10BaseT twisted pair), PS/2, RS-232-C, Centronics, floppy disk drive, and
the display. Proprietary ASICs are used as device interfaces to the I/O
components.
Graphics
The Graphics, or display, is a proprietary graphics accelerator ASIC supported by
2 MB of Synchronous Graphics RAM. The Graphics ASIC has two video outputs.
One video output is an RBG signal routed to the I/O Board. The second video
output is a digital video signal which is routed to a connector on the CPU board.
The digital video signal is utilized by the 16702A mainframe flat panel display.
PCI Board
The PCI board bridges the PCI backplane of the CPU board to an instrument
backplane that interfaces with the measurement modules. Instrument backplane
control is managed by the PCI board.
8-5
Theory of Operation
Subsystem overview theory
PCI control functionality includes:
•
Intermodule bus (IMB) with fixed and mixed trigger event inputs, module ARM, and
port in/out
•
2 ns data time correlation across measurement modules
•
Intermodule signaling bus
•
Interframe signaling bus
•
Target control bus
•
Synchronous module data acquisition
Additionally, the PCI board provides I/O port capability that is not available on the
CPU board. The I/O port capability is extended to the I/O board. I/O port
capability includes:
•
External single-ended SCSI
•
Internal SCSI
•
LAN (10Base2)
•
Port In/Out
Because it is the interface between the CPU and the instrument measurement
front end, the PCI board hardware is suspect in the event the PV software (SelfTest) fails to load when initiated.
8-6
Theory of Operation
Subsystem overview theory
Interface Board
The interface board distributes most of the signals from both the CPU board and
the PCI board throughout the system. Additionally, the interface board provides
additional functionality not found on either the CPU or PCI board.
The interface board includes circuitry to synchronize the 100 MHz backplane
module sample clock with the 500 MHz sample correlation clock to improve
sample time correlation. It also includes the audio beeper and the fan speed
control.
8-7
Theory of Operation
Subsystem overview theory
Measurement Module Backplane
The measurement module backplane is the same backplane used in the Agilent
Technologies 16500-series logic analysis system. Consequently most of the
16500-series modules existing at the time of the Agilent Technologies 16600series and 16700-series releases will operate in those mainframes. Additional
enhancements are also present to accommodate newer 16700-series modules.
Enhancements include a common sample clock to improve measurement time
correlation and an optional handshaked transfer and 16-bit multiplexed address/
data bus transfer to speed data transfer from the modules to system memory.
Emulation Module Interface
Processor run control, provided by the Emulation Module, is used to control the
target system processor execution and allow access to target system resources.
Target system processors viable for use with the Emulation Module will include
some form of N-wire control. Access to the Emulation Module will be through the
mainframe interface.
The Emulation Module is a Motorola 68332 system. The 68332 processor is used
to control the N-wire and JTAG protocols for the target system processor.
The Emulation Module will physically reside on the measurement module
backplane. Communications between the mainframe CPU and the Emulation
Module is managed by a run control server on the CPU board. The server
manages the interrupts to and communications with the 68332 processor on the
Emulation Module. Memory-mapped I/O allows the CPU to communicate with
the Module for data transfers.
Power Supply
The power supply provides all power to the logic analysis system. The input
voltage is autoselecting with respect to both voltage and frequency. The DC
output voltage provided includes -12 V, -5.2 V, -3.25 V, +3.4 V, +5.1 V, and +12 V.
The mainframe itself consumes 100 W of power. Each measurement module has
an 80 W power budget, and each emulation module has a 25 W power budget.
Maximum power consumed in a fully loaded mainframe is 630 W. The flat panel
display in the 16702A mainframe consumes only 6 W of power.
8-8
Theory of Operation
Subsystem overview theory
Power Control
The front panel power switch does not directly control the line voltage. The
power switch manages a control circuit through the CPU. When power is applied,
the control circuitry immediately responds to input from the power switch.
When the instrument is turned off without initiating a Shutdown, the power
switch asserts an interrupt to the CPU. The CPU then begins system cleanup in
preparation for powerdown. When system cleanup is completed, the instrument
then powers down.
Note that if the front panel switch is disconnected from the interface board, the
instrument will never power down.
Power Sense
The Power Sense circuitry, managed by the CPU, directly controls the state of the
power supply. A control signal is directed to the power supply through the power
sense cable. When the control signal is asserted, the power supply will activate.
The power supply will then deactivate when the control signal is de-asserted.
Note that if the power sense cable is disconnected from the interface board, the
instrument will never power up.
8-9
The Power-Up Routine
When power is applied to the 16700-series logic analysis system mainframe, a
series of tasks called the power-up routine is performed to initialize and to verify
operation of the mainframe. The mainframe display reports the progress and
status of the power-up routine. Each of the tasks of the power-up routine is
scrolled onto the mainframe display as the task is being performed.
The following is a complete listing of the power-up routine dialogue (or boot
dialogue). The parts of the power-up routine dialogue are then discussed. Some
of the details may vary slightly depending on the firmware revisions.

If the system was previously powered down abnormally, then the file system
would include a journal file. The instrument would then replay the detected
journal file in an attempt to recover the instrument state prior to the abnormal
shutdown. During the remainder of the boot routine in this case, the text "Log
replay in progress" appears repeatedly in the boot dialogue.
The system memory is again tested. If 64 MB of system memory was installed,
the following message appears:

Physical: 65536 Kbytes, lockable: 39088 Kbytes, available 47856 Kbytes
For the remainder of the isl boot stage, the file system is further checked. The
devices on the backplane are also checked and configured.
Initialization
During initialization, all of the hardware subsystems and supporting software
processes are initialized and started. Most failures at this point will be caused by
software or configuration errors.

Logic Analysis System load
After the instrument core subsystems are tested and configured, the final stage of
the power-up routine begins. During the final stage, the logic analysis system
software is loaded. The logic analysis system software includes the mainframe
and module software, and toolset licenses.
The system is ready. Starting Logic Analysis System ...
The CPU and the devices on the CPU backplane that form the infrastructure of
the system are tested and are operational. Now the CPU polls the devices on the
measurement module backplane. After reading the ID codes of the installed
modules, the CPU then loads the appropriate measurement module software
from the boot device into system memory. After the module software is
downloaded into memory, the modules are initialized and calibration factors are
loaded (for modules requiring cal factors from an operational accuracy
calibration).
The session manager autolaunches, which in turn autolaunches a local logic
analysis session. When the System window appears, the instrument is ready for
use. Any module configuration errors appear in a status window when the
System window is opened.
8-17
Self-Tests Description
Performance Verification, or Self Test is made up of a series of software routines
that exercise instrument subsystems to verify that the subsystems are
operational.
Performance Verification is performed at two levels: on boot, and using the
performance verification software (PV software). The two levels of performance
verification are designed to be complimentary. That is, if a subsystem is tested
during boot, there will not be a user-initiated performance verification test in the
PV software to operationally verify the same subsystem. Likewise, the PV
software is designed to test the operation of instrument subsystems that have not
been tested on boot.
When you initiate the PV software, the measurement session will be exited,
discarding all measurement configurations. You will be warned of this prior to
entering the PV software to give you the opportunity to cancel loading of the
software. The measurement session is exited since the PV software tests will
leave the hardware in an unknown state. Restarting the measurement session
after running the PV software is required to properly re-initialize the hardware to
again run measurements.
Performance Verification on boot
During powerup, both the CPU and system memory are tested as part of the
initial firmware execution. This occurs very early in the power-up boot routine.
After the CPU and memory tests are complete, the display will show that the
firmware recognizes both the CPU and system memory.
When the memory has been tested and passes, the display will show the following
message:
Memory Test/Initialization Completed
When the CPU has been tested and passes, the display will show the following
report about the CPU:
Processor
--------0
Speed
-------150 MHz

--------------------Active
Available memory (bytes)
:
Good memory required (bytes):
Coprocessor State
----------------Functional
Cache Size
---------64 KB
67108864
67108864
This shows that 64 MB of system memory is installed and recognized by the boot
ROM. If 160 MB of system memory is installed, then the number of available
bytes would be 167772160. However, if the CPU system memory daughter card is
not installed or not properly seated, then only the base 32 MB system memory
would be recognized, and the boot dialogue would show only 33554432 bytes
available.
8-18
Theory of Operation
Performance Verification using the PV software
The hard disk drive is then tested during this phase of the power-up boot
routines. During the initial firmware execution, the hard disk drive is searched
for. When the hard disk drive is found, the display will report:
Trying Primary Boot Path
-----------------------Booting...
The instrument then attempts to boot from the hard disk drive. Operation of the
hard disk drive is verified, after which the instrument loads the operating system.
The following message is displayed when the operating system begins to load:
ISL booting hpux
boot
disk(8/16/5.6.0.0.0.0.0;0)/stand/vmunix
3526196 + 315392 + 298272 start 0x192368
When the above message appears, it implies that the instrument central
processor, system memory (RAM), and hard disk drive are operational. If any of
these subsystems are not operational, an error message will appear and the boot
process will halt. Refer to the troubleshooting flowcharts for more information
on boot errors.
Performance Verification using the PV software
The PV software (Self Test) provides additional confidence in the operation of
the instrument by verifying subsystems that are not tested as part of the boot
routines. The tests are divided between System Tests and Frame Tests.
System Tests
The System Tests verify the operation of the logic analysis system core that have
not been tested during power-up boot routines. Verified during the System Tests
are the PCI board and parts of the CPU board not tested during boot.
When "Test All" is selected, some of the tests will not run, and will return a "Not
Executed" status because operator action is required. You must select and run
these tests individually. When the tests requiring user action are run, you are
prompted for the specific action that is needed for successful completion of the
test. When the indicated user action is performed, and the tested subsystem is
operational, the specific test will return a "Passed" status.
8-19
Theory of Operation
Performance Verification using the PV software
For the CPU board, the tests that require user action are:
Test:
User Action:
Floppy Drive Test
External SCSI Test
Parallel Port Test
A DOS-formatted floppy must be in the drive.
A powered-up CD-ROM drive must be on the bus.
A parallel port loopback connector must be installed.
Passing the System Tests (CPU Test and PCI Test) implies that the CPU board is
fully operational and can communicate with the rest of the instrument, with
peripherals, and with other networked devices.
Front Panel Tests (16702A only)
Because the 16702A mainframe includes a front panel keypad and display, a front
panel test is included as part of the system tests. The front panel test is not
launched when Test All is selected. User action is required to launch the test.
When the front panel test is launched, a graphic of the front panel is displayed on
the instrument display. You then press each of the front panel keys, which
toggles the color of the corresponding key graphic. At the conclusion of the test,
you determine whether the test passes or fails.
Frame Tests
The Frame Tests verify the operation of the measurement modules installed in
the logic analysis system.
In the 16700-series, module tests are available for modules installed in the
mainframe and in the expander frame (if installed). In the Self Test window, one
tab is labeled Master Frame. A second tab, labeled Expander Frame, appears if
an expander frame is installed in the system. The slots are designated:
Master Frame tab
Slots A-E - Installed Measurement Modules
Slots 1,2 - Installed Emulation Modules
Master Frame tab
Slots F-J - Installed Measurement Modules
Slots 3,4 - Installed Emulation Modules
The installed measurement modules are listed under the selection tabs. Each
module can be selected to yield a list of tests available for that module. Some of
the measurement modules are composed of multiple cards, where one card is
called the master and the other cards are called expanders. PV for a multiplecard set is always tested through the master card. Test results for the expander
cards will track results for the master card. In some cases, the PV software can
distinguish between problems on the expander cards and the master card. In this
8-20
Theory of Operation
Performance Verification using the PV software
case, the failure counts shown on an expander card may differ from those shown
for a master card. For more information, refer to the service manual of the
specific measurement module of interest.
When "Test All" is selected, some of the tests will not run and will return a "Not
Executed" status because operator action is required. You must select and run
these tests individually. When the tests requiring user action are run, you are
prompted for the specific action that is needed for successful completion of the
test. When the indicated user action is performed, and the tested subsystem is
operational, the specific test will return a "Passed" status.
For the Agilent Technologies 16610A Emulation Module, the test requiring user
action is:
Test
User Action
Internal PV Test
A loopback connector must be installed.
For the existing 16500-series measurement modules, the tests requiring user
action are:
16517A Timing Module
Test
User Action
Skew Adjust
Not a test; used for operational accuracy calibration (de-skew).
16522A Stimulus Module

Test
User Action
ADC Test
There must be no stimulus on the scope inputs.
16550A State and Timing Module

Not a test; provides continuous output of signal input levels.
Passing the Frame Tests implies that all installed measurement modules are fully
