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
to 660 MHz, multi-level and multitiming 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
Timing values can now be swept
without the danger of misleading
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. Along with 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-c ycle),
and load compensation ensure a
high level of convenience.
Stimulate 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- ze ro) 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 u p 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.

device-under- test.
Trigger Modes
Continuous: Continuous pulses, dou-
ble pulses or bursts (single or double pulses).
External triggered: Each active input
transition (rising, falling or both)
generates a single or double pulse
or burst.
External gated: The active input level
(high or low) enables pulses, double
pulses or bursts. The last single /
double pulse or burst is always
completed.
External width: The pulse shape can
be recovered whilst the period and
width of an external input signal
are maintained. Levels and transitions can be set.
Manual: Simulates an external input
signal.
Internal triggered: Internal PLL
replaces an external trigger source.

PLL Reference: The internal PLL is
locked to an external 5 MHz or 10

determined by the signal at CLK
input.
