81100 Family
Pulse/Pattern Generator
Technical Specifications
Flexible pulses or patterns for digital
designs
Key Features
· Common operation with the easy
to-use 8110A-type graphical user
interface
· Common programming. All 81100
models and the 8110A use the
same GP-IB/SCPI commands
· 100% form/fit compatibility
· User-retrofittable channels for
most models
· Upward compatibility
· Individual solutions for frequencies
up to 50, 80, 165, 330, 400 and
660 MHz
· Pattern mode on all models from
80 MHz. Include pseudo-random
binary sequence
· The outputs of dual-channel
instruments can be added (analog
or EXOR, depending on model).
Introduction to the 81100 Family
All members have the same
programming/user interfaces,
which are compatible with the
well-established Agilent 8110A.
Migration is therefore easy and
cost-effective.
Signals for testing digital designs
and components
The Agilent 81101A, 81104A, 81110A
and 81130A generate all the standard
pulses and digital patterns needed to
test current logic technologies
(CMOS, TTL, LVDS, ECL, etc.).
With the optional second channel on
all of the models from 80 MHz,
multi-level and multi-timing
signals can be obtained using the
internal channel addition feature.
· Variable pulse parameters in
pattern mode as well as in pulse
mode (not on the 81130A)
· Synchronously triggerable
· Simulation of reflections/
distortions (81104A, 81110A)
· Three/four-level codes (81104A,
81110A)

Glitch-free timing changes
Now you can sweep your timing
values without the danger of
spurious pulses or dropouts that
could cause measurement errors.
(Applies to continuous mode,
values < 100 ms, consecutive
values between 0.5 and twice the
previous value on the 81101A,
81104A, 81110A)
Reliable measurements
All models provide clean,
accurate pulses with excellent
repeatability, thus contributing to
measurement integrity.
The Agilent 81110A features selfcalibration for more accuracy. It also
offers a choice of output modules: the
Agilent 81111A 165 MHz, 10 V
module with variable transitions and
the Agilent 81112A 330 MHz, 3.8 V
module which has differential outputs
and two selectable transition times.
The Agilent 81130A offers a choice of
output modules: the Agilent 81131A
400 MHz, 3.8 V module and the
Agilent 81132A 660 MHz, 2.5 V
module which has complementary
outputs.
Easy-to-use
Features such as the clear
graphical display, autoset, help,
store/recall, preset TTL/ECL
levels, selectable units (such as
current/voltage, width/duty-cycle),
and load compensation ensure a high
level of convenience.
Smooth integration into automated
test systems
The Agilent 81100A family can be
integrated easily into all phases of
test system development. Test
programs are 100% upwardly
compatible from the Agilent 81101A
to the 81104A and from the 81104A
to the 81110A, ensuring that growth
with future needs is as easy as just
exchanging the instruments
physically. This results in low
integration costs, in addition to low
costs of ownership through proven
hardware reliability.
Emulate the device's
environment...
Today's devices can require very
complex stimuli. To meet this, the
Agilent 81130A can sequence and
loop its memory for very deep
patterns. RZ (return-to-zero), NRZ
(non-return-to- zero) and R1 (returnto-one) formats are available. Digital
channel addition allows the
generation of signals with two
different pulse widths and delays or
of data rates up to 1.32 Gbit/s in one
single channel.
Frequency range
The Agilent 81130A is designed and
recommended for an operation in the
frequency range of 170 kHz to
400/660 MHz. However it can be
operated in the extended range down
to 1 kHz.
