8110A 150 MHz Pulse Generator

The Agilent 8110A 150 MHz Pulse
Generator is a test instrument
that provides sufficient speed and
performance for testing designs to
their limits; testing under real­world conditions to verify the
proper function of the design.

· pulses, digital patterns and
multilevel waveforms for testing
current logic technologies

(CMOS, TTL, LVDS, ECL, etc.)

· credible measurements

· easy set-up and operation

· upgrade capability

Real World Pulses

With the pattern feature and the
the optional second channel of
the Agilent 8110A, real world s
ignals, like reflections, distorted
pulses, or three or even four-level
signals can be simulated.

Pattern Based Timing

The Agilent 8110A simulates all
the clock and data signals needed
to test digital designs. Conditions
such as extended delays can be
generated using pattern based
timing features.

Clean Pulses

The Agilent 8110A generates
clean pulses with 10 ps
resolution, low jitter and good
pulse performance across all
operating temperatures or
settings. Parameters and trigger
modes can be changed without
generating unwanted pulses, so
that reliable measurements are
guaranteed.

High Accuracy

Excellent accuracy over a wide
temperature range guarantees
repeatable measurement results.
Frequency accuracy, jitter,
resolution and range can be enhanced
further when the Agilent 8110A is
used with the internal phase locked
loop (PLL) of the Agilent 81106A as
pulse period source.

Delay Calibration

Systematic delays caused by cables,
connections and adapters can be
compensated when the Agilent
81107A is installed. It offers enough
additional delay range to compensate
for 5 m of BNC cable.

External Clock or Reference
Frequency

1

An external synthesizer or system
clock can be used as clock source at
the clock input of the Agilent 8110A
to achieve the frequency accuracy
and required. This
feature is ideal for simulating
digital control signals
synchronously to the clock of the
microprocessor.

Up to 10 channels in parallel

2

Up to 4 Agilent 8110As can be slaved
to a master, so that 10
synchronous channels can be
programmed independently. With the
Agilent 81107A multichannel deskew
installed, the propagation delay of the
set-up can be
compensated, and all other output
channels zeroed to the reference
channel.

Smooth Integration into Automated
Test Systems

The Agilent 8110A can be smoothly
integrated into automated test
systems, ensuring:

· low integration costs

· low costs of ownership

All Digital Waveforms

The waveform and trigger
flexibility of the Agilent 8110A make
it a universal digital
stimulus for any automated test sys­tem.

Reliable Measurements

Accuracy is specified over the whole
temperature range that exists in a
test rack. Setting check and built-in
diagnostics allow you to monitor the
correct operation of the Agilent
8110A in an automated test system.

Easy Rack Integration

The small size of the Agilent 8110A
saves valuable rack space. Rear panel
connectors and rack mount kits are
optional.

Reduced Programming
Investment

The local user interface eases the
transition from manual to
automated measurements and from
the R&D bench to
automated manufacturing test. All
parameters of the Agilent 8110A are
programmable via GPIB. SCPI
(Standard Commands for
Programmable Instruments)
facilitates the standardization of test
programs.

Low Cost of Ownership

The proven hardware reliability of
Agilent test and measurement prod­ucts results in high uptime of test
systems and low maintenance costs.
The Agilent 8110A offers a 3 year
standard warranty.

Easy Set-up and Operation

View all timing parameters for both
channels at a glance. Timing and
level parameters can be entered in
any format, e.g. period as frequency.
The alternative graphic display shows
the timing relationship of all pulse
parameters on both channels
graphically, making setting up the
pulse generator easy - no extra
oscilloscope is required.

Pulses and patterns can be set up
quickly using the convenient
cursor keys, knob and data entry
keys. You can even use the Autoset
Key to resolve all timing conflicts.

Memory Card

Settings can be stored
permanently either internally or on
the memory card for duplication in
another test set-up.

Agilent 81106A PLL/External Clock
for the Agilent 8110A

Can be retrofitted without
recalibration. Useful for
applications which require a phase
locked loop (PLL) or an external
clock:

Locking to an external frequency
reference: the internal PLL is locked

to the 5 MHz or 10 MHz frequency at
the PLL reference input.

High accuracy: the output period is

determined by the internal PLL.
Period accuracy, range, resolution,
and jitter are improved as shown in
the diagram. Asynchronous trigger­ing possible.

Internal triggered burst: the internal

PLL replaces an external trigger
source.

External clock: the output period is

determined by signal at clock input.
Frequency accuracy can be increased
by using a precise external clock.

Trigger synchronously to external
clock:

the output period is
synchronous to the signal at clock
input. The signal at external input is
used for arming.
