Agilent 81100 Family of
Pulse/Pattern Generators
The Agilent Technologies 81101A
pulse generator belongs to the 81100
family. All members have the same
programming and user interfaces
that are compatible with the wellestablished Agilent 8110A. Migration
is therefore easy and cost effective.
Signals for testing digital designs
and components
The 81101A generates all of the
standard pulses needed to test
current logic technologies (CMOS,
TTL, ECL, etc.);
• Variable pulse parameters.
• Can be triggered in syncrony.
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).
Reliable measurements
The 81101A provides clean, accurate
pulses with excellent repeatability,
thus contributing to measurement
integrity.
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.
Agilent 8110A user interface.
Variable transitions.
Up to10 Vpp (20 Vpp) into 50 Ω.
3.5 digits timing resolution, best
case 5 ps.
0.01% frequency accuracy.
Fully SCPI programmable.
Broad range of trigger and synchronization capabilities.
Dropout and glitch free change
of any timing parameters.
8.9 cm height, full rack width.
Graphical display.
Smooth integration into automated
test systems
The 81101A can be integrated easily
into all phases of test system development, such as planning, rack integration, and test program generation.
Test programs are 100% upwardly
compatible to the 81104A and 81110A,
ensuring that growth with future
needs is just as easy as exchanging
the instruments themselves. This
results in low integration costs, in
addition to low costs of ownership,
through proven hardware reliability.
Specifications
Specifications describe the instrument’s warranted performance. Nonwarranted 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.

Transition times: These can be entered
as leading/trailing edge or % of width.
Leading and trailing edges are independent within one of the following
overlapping segments (1:20 ratio):

better than accuracy.

Internal triggered:
Internal PLL replaces an external
trigger source.

input: One input (BNC connector at
rear panel) is used for clock input or
alternatively for the PLL.
PLL Reference: The internal PLL is
locked to an external 5 MHz or 10 MHz
reference frequency.
