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.

Specifications
Specifications describe the instrument's warranted performance. Non-warranted values are described as typical. All specifications apply
after a 30 minute warm-up phase with 50 Ω source/load resistance and separate channels. All specifications are valid from 0°C to 55°C
ambient temperature.
Timing Characteristics
Measured at 50% amplitude at fastest transitions in continuous mode and 50 Ω source impedance.
Burst Count: 2 to 65536 (single or
double pulses).
Delay: delay, phase or % of period.
Fixed delay: 34 ns typical
Double pulse and delay:
mutually exclusive.
Duty cycle: set between 0.1% and
94.0% (subject to width limits.
99.9% with overprogramming).
Repeatability: is typ. four times
better than accuracy.
Transition times: leading/ trailing edge
or % of width. Leading and trailing
edges are independent within one of
the following
overlapping segments
(1:20 ratio): 2 ns (3 ns) - 20 ns,
10 ns - 200 ns, 100 ns - 2 ms,
1µs - 20 µs, 10 µs - 200 µs,
100 µs - 2 ms, 1 ms - 20 ms,
10 ms - 200 ms.
Overprogramming: values can be
entered exceeding the specified
range.
