WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
These products are not specically designed for use in hazardous environments, for example in
explosive atmospheres. If a product is to be used in hazardous environments we recommend that
the user ensures suitable protective measures are taken.
!
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
These products may contain hazardous voltages. Before removing the products remove all supplies
and disconnect user I/O signals.
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL
Certain semiconductor devices used in this equipment are liable to damage due to static voltage.
Observe the following precautions when handling these devices in their unterminated state, or
sub-assemblies containing these devices:
1. Persons removing sub-assemblies from equipment using these devices must be earthed by a
wrist strap and a resistor at the point provided on the equipment.
2. Soldering irons used during the repair operations must be low voltage types with earthed tips and
isolated from the mains voltage by a double insulated transformer.
3. Outer clothing worn must be unable to generate static charges.
4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in
anti-static bags.
CAUTION - PRODUCT DOCUMENTATION SYMBOL
Suitably qualied & trained users should ensure that the accompanying documentation is fully read
and understood before attempting to install or operate the product.
!
SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user
I/O signals.
• Appropriate manual handling procedures should be followed as dictated by the weight of the individual product or
the combined weight of the relevent products.
• Should a fault occur with the product, unit or chassis, immediately isolate and disconnect the incoming power to the
relevent products, and the user I/O signals.
• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.
• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on
the front of the unit.

pickering SECTION 1 - INTRODUCTION
SECTION 1 - INTRODUCTION
This manual describes a range of products designed to support the implementation of test systems that contain a
Wired Trigger Bus conformant to the LXI standard. The components can be also used in the compliance testing of
LXI Devices with WTB capability and to allow a test bench to be constructed demonstrating the operation of the
WTB.
The key items covered by this manual are:
•60-981. Wired Trigger Probe. The probe allows an oscilloscope or similar device to be used to
monitor the analog waveforms present on the differential pairs that carry the M-LVDS signals. The
probe is particularly useful for diagnosing faults on the WTB and testing component parts in the
system.
•60-982 WTB Adaptor. The adaptor allows signals from LVTTL sources to be transferred to WTB
signals on any of the 8 channels that make up the WTB. The adaptor can be manually congured
or controlled through a digital I/O interface. In addition signals that are present on the WTB are
converted to LVTTL signals. The adaptor is a simple method of connecting trigger signals to and from
products without a WTB capability (including non LXI products).
•60-983 Terminator. Provides a simple terminator required to terminate the WTB transmission lines.
•60-984. Extender. Allows WTB cables to be connected together to extend their length, useful when
the user does not have WTB cables of the right length
•60-985. WTB cables. A variety of different length cables suitable for connecting together LXI devices
with WTB capability.
•60-990. Agilent Scope Adapter. Allows the logical state of all 8 WTB channels to be displayed on
an Agilent 6000 or 8000 series oscilloscope.
More information on the LXI standard and the LXI WTB can be found on the LXI web site www.lxistandard.org . A
tutorial on the LXI WTB is provided in Section 4 of this manual.
LXI Conformance
At the time this manual was created the products described have not been certied by the LXI Consortium as
complying with the LXI Specication. However, they have been tested in association with LXI Devices and it is
believed they that they are compatible with the essential electrical and physical characteristics of the LXI Wired
Trigger Bus. It is anticipated that some devices will be tested for compliance for the Termination aspects of the
standard.
