Service Safety Summary

Only qualified personnel should perform service procedures. Read this Service
Safety Summary and the General Safety Summary before performing any service

procedures.
Do Not Service Alone. Do not perform internal service or adjustments of this

product unless another person capable of rendering first aid and resuscitation is
present.

of the power cord or, if provided, the power switch.

Use Caution When Servicing the CRT. To avoid electric shock or injury, use
extreme caution when handling the CRT. Only qualified personnel familiar with
CRT servicing procedures and precautions should remove or install the CRT.

CRTs retain hazardous voltages for long periods of time after power is turned off.
Before attempting any servicing, discharge the CRT by shorting the anode to
chassis ground. When discharging the CRT, connect the discharge path to ground
and then the anode. Rough handling may cause the CRT to implode. Do not nick
or scratch the glass or subject it to undue pressure when removing or installing it.
When handling the CRT, wear safety goggles and heavy gloves for protection.

Use Care When Servicing With Power On. Dangerous voltages or currents may
exist in this product. Disconnect power, remove battery (if applicable), and
disconnect test leads before removing protective panels, soldering, or replacing
components.

To avoid electric shock, do not touch exposed connections.
X-Radiation. To avoid x-radiation exposure, do not modify or otherwise alter the

high-voltage circuitry or the CRT enclosure. X-ray emissions generated within
this product have been sufficiently shielded.

There are no adjustments or certifiable parameters for the TLA711 Benchtop
Chassis. Refer to the TLA 711 Color Benchtop Controller Service Manual for
more information on adjustment and certification of the controller.

This manual supports and contains all the information needed for periodic
maintenance of the Benchtop Chassis. (Examples of such information are
procedures for fault isolation of a failed circuit board or assembly and for
removal and replacement of same.)

This manual also supports and contains information for corrective maintenance
of this product:

H supports isolation of faults to the failed circuit board or assembly level

shown in the replaceable parts list of Chapter 10

H supports removal and replacement of those boards or assemblies
H supports removal and replacement of fuses, knobs, chassis, and other

mechanical parts listed in the replaceable parts list
This manual does not support component-level fault isolation and replacement.

Specifications

Product Description

This chapter provides a general description of the Benchtop Chassis and a list of
specifications under Characteristics Tables beginning on page 1–3.

The Benchtop Chassis is designed to be used as part of a TLA 700 Series Logic
Analyzer. It is an intelligent, 13-slot chassis with the following features:

H High output power supply
H Intelligent cooling for installed modules
H High quality auto-configurable backplane
H Optional adjustable rackmounts

Standard features are explained in more detail in the following paragraphs. Refer
to the Options chapter for a description of optional features.

Power Supply

Intelligent Cooling

The Benchtop Chassis provides voltages at levels sufficient for the most
demanding TLA 700 Series applications. The power supply has a volt-ampere
capacity of 1660 VA with 872 watts usable by TLA 700 Series instrument
modules at any one time. The chassis accommodates exclusively digital
applications (using the logic analyzer module), exclusively analog applications
(using the DSO module), or combinations of both.

The power supply plugs directly into the rear of the chassis and has no cables to
disconnect. Because of this design, you can replace the power supply in less than
three minutes, keeping downtime to a minimum. The power supply automatical­ly accommodates the appropriate input voltage and frequency; no mechanical
switch is required to select the correct line voltage.

The Benchtop Chassis provides optimal cooling for all installed modules. The
chassis uses an intelligent, adaptive cooling scheme to efficiently remove heat
while maintaining quiet operation. When you set the blower to variable speed
(default), the chassis automatically adjusts the blower speed to keep the
temperature rise above the modules to approximately 10° C, or less. Using a rear
panel switch, you can set the blower to full speed to provide maximum cooling
at all times.

1–1

Specifications

Air is exhausted at the sides of the chassis allowing you to stack the chassis with
other rackmount equipment. You don’t have to to worry about restricting any
airflow out of the top of the chassis or creating a chimney effect.

Cooling is not wasted on empty slots. Card guides automatically direct air to
only those slots containing modules; empty slots are shut off. The chassis directs
airflow across each installed module from the bottom to the top of each slot.
Baffles balance the airflow from the front to back and across occupied slots in
the chassis.

You can replace the blower without disassembling the entire chassis.

Backplane

The Benchtop Chassis has an autoconfigurable, solid-state backplane that uses
electronic jumpering of the IACK and BUS GRANT signal lines. There are no
jumpers to move or install on the backplane. This results in a high quality
backplane that is ideal for automatic test environment systems that must be
reconfigured frequently.

Full differential distribution of the CLK10 signals provide a clean timing source
for your TLA 700 Series instruments.
