Safety Information
Safety
This is a Safety Class 1 instrument (provided with terminal for protective
earthing). Before applying power, verify that the correct safety
precautions are taken (see the following warnings). In addition, note the
external markings on the instrument that are described under Safety
Symbols. Do not operate the instrument with its covers removed.
Replace fuse only with specified type.
Warning
Before turning on the instrument, you must connect the protective earth
terminal of the instrument to the protective earth conductor of the
(mains) power cord. The mains plug must only be inserted in a socket
outlet with a protective earth contact. Do not negate the protective
action by using an extension power cord without a protective grounding
conductor. Grounding one conductor of a two-conductor outlet is not
sufficient protection.
Service instructions are for trained service personnel. To avoid
dangerous electric shock, do not perform any service unless qualified to
do so. Do not attempt internal service or adjustment unless another
person, capable of rendering first aid and resuscitation, is present.
If you energize this instrument using an auto-transformer (for voltage
reduction), make sure that the common terminal is connected to the
earth terminal of the power source.
Whenever it is likely that the ground protection is impaired, you must
make the instrument inoperative and secure it against any unintended
operation.
Do not operate the instrument in the presence of flammable gases or
fumes. Operation of any electrical instrument in such an environment
constitutes a definite safety hazard.
Do not install substitute parts or perform any unauthorized modification
to the instrument.

What you can do with the
81110A/81104A
This section introduces the basic features and use models of the
81110A/81104A Pulse and Pattern Generators.
Basic Features
The Pulse and Pattern Generators generate all standard pulses, digital
patterns and multi-level waveforms needed to test all current logic
technologies (such as TTL, CMOS, ECL, PECL, LVDS, GTL) and other
digital designs up to 330 MHz.
The instruments provide a reliable and wide range of signals, which can
be used in even more applications than its predecessor, the
Agilent 8110A. This is due to enhancements made in the feature set and
specifications of the Agilent 8110A. The glitch and drop out free varying
of any timing parameter and the timing calibration feature of the Agilent
81110A/81104A contribute to more accurate and confident
characterizations of the DUTs.
Benchtop Testing
The 81110A/81104A feature a graphic display showing all pulse
parameters at a glance. The cursor keys and the modify knob allow fast
and simple operation.
The user interface is designed to minimize the time invested in getting
familiar with the instrument. After familiarization, the instrument
supports quick setups of signals. This leaves you free to concentrate on
the measurement task and testing of the DUT.

Automated Testing
The 81110A/81104A has the same SCPI conform command structure for
the feature sets identical to the Agilent 8110A. As with the Agilent 8110A,
the new product can be easily integrated into all phases of test system
development such as planning rack integration and test program
generation. These benefits along with the low cost of ownership make
the 81110A/81104A an invaluable instrument in a wide range of technical
applications. Programs designed for the Agilent 81104A can be used
without any changes for the Agilent 81110A with Agilent 81111A
10V/165 MHz outputs.

The Agilent 81110A compared to the Agilent 81104A has better accuracy,
up to 330 MHz clock rate, 800 ps typical edges at up to 3.8 V, and a timing
auto calibration.
Upgrade Capability
It is possible to upgrade the instruments with a second channel if only
one channel was originally ordered. There are two output channels
available for the Agilent 81110A. The second channel that is installed
must be the same as channel one.

 The external input (EXT INPUT) can be used to connect an external
arming source (started or gated modes). For details, please refer to
The Mode/Trigger Screen on page 60.
 The trigger signal (TRIGGER OUT) marks the start of the pulse
period or of parts of a pattern (see The Mode/Trigger Screen on
page 60). You can set the output levels according to the used
technology (TTL, ECL, PECL) or enter test-specific values (see The
Trigger-Level Screen on page 96).
 The strobe signal (STROBE OUT) marks beginning and end of a burst
in Burst mode. In Pattern mode, this signal is programmable per bit.
