Agilent Technologies
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-l evel 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
(return-to-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 i n the extended range
down to 1 kHz.

Pattern and Sequencing
Pattern length: 65504 bit/channel. If

PRBS is used: (65503-PRBLength)
Pattern formats: NRZ (non-return-to ­zero), DNRZ (delayed non-return­to-zero), RZ (return-to-zero) and
R1 (return-to-one) can be selected
(see figure 1)

On/off: Relays connect/disconnect
output (HiZ).

Sequencing: A sequence is a
succession of segments. One outer
loop running once or continuous,
and one nested loop can be
applied. The nested loop can be set
from 1 to 2^20 repetitions.
Segment: The memory can be divid­ed into maximal 4 segments.
Segment length resolution: This is the
resolution for which the segment
can be set dependent on the maxi­mum data rate. (see table 1)

Limit: Programmable high and low
levels can be limited to protect the
device-under- test.

Segment types: Pattern, PRBS,
high and low segments ( "0" or "1"
levels segments selectable).
Note: If one channel is set to PRBS
the other channel can only be high
or low segments, or PRBS type.
Random Pattern: PRBS 2^n-1,
n = 7,8,...,15 (CCITT 0.151)

Digital Channel Addition

Channel 1 can be logically
combined with channel 2 (XOR) as
shown in Figure 2 . The source
impedance remains 50 Ω. Output 1
is still available in this case.

Trigger Modes
Continuous: Continuous pulses, bursts

or patterns.
External started: Each active input
transition (rising, falling edge)
generates pulses, bursts or patterns.
External gated: The active input level
(high or low) enables pulses, bursts
or patterns. On an external gate
signal the output is immediately
stopped, that means the last cycle
will not be completed.
Manual: Simulates an external input
signal with push of a front panel
button.

Ordering Information - 81100 Family

The minimum configuration for a working instrument consists of a mainframe and one output module.
The second output module can be added later. Output modules can be exchanged and retrofitted by
the user. The English Quick Start Guide (811xx-91010) and Reference Guide (811xx-91011) is supplied
with each mainframe for all configurations. A memory card is not included.

Each Agilent 81101A includes just
one output channel (in
comparison to the other models of
the Agilent 81100 family). The out­put module of the 81101A does not
need to be ordered separately.
