Agilent 81133A and 81134A
3.35 GHz Pulse Pattern Generators
Data Sheet
Version 1.3
81133A and 81134A
3,35 GHz Pulse Pattern
Generators
The need for pulse and pattern
generation is fundamental to
digital device characterization tasks.
The ability to emulate the pulse
and pattern conditions to which
the device will encounter in its
final application, is essential. This
emulation should include both typical
and worst case conditions. Accurate
emulation requires superlative signal
integrity and timing performance
along with full control over parameters that allow specific worst case
testing.
Setting Standards
The Agilent 81133A and 81134A
3.35 GHz Pulse Pattern Generators
provide programmable pulse periods
from 15 MHz (66.6 ns) to 3.35 GHz
(298.5 ps) on all channels. With
frequency ranges this fast, the
transition time performance becomes
critical; the Agilent 81133A and
81134A perfom at less than 60 ps
transition. With a RMS jitter of
1.5 ps (typ), the best signal quality is
assured. The Delay Control Input and
the Variable Crossover Point functionalities allow fast and easy Signal
Integrity measurements, including
emulation of real world signals by
adding jitter to clock or data signals
or by distorting the ‘eye’ for eye
diagram measurements.

Connectors
Main Modes
Front panel connectors
All signal outputs and inputs are
accessible at the front panel.
These are:
•2 (or 4) output connectors for the
1 (or 2) differential channel(s)
•Trigger output
•Clock input
•Start input
•1 (or 2) delay control input(s) for the
1 (or 2) channel(s)
Rear panel connectors
Remote programming interfaces:
GPIB, LAN, USB 2.0 (see also
‘Additional Features’)
Clock Source
Selecting the clock source determines
the origin of the time base. All other
timing parameters are derived from it.
There are two choices:
Internal
Direct mode (direct internal/
direct external)
The direct modes allow changes of
frequency without dropouts in the
range of 1:2. This can be used for
applications, where dropouts would
make a measurement impossible
(e.g.: PLL frequency sweep, micro
processor clock sweep). In both direct
modes, the delay and deskew of all
channels is set to zero (deskewed at
the connectors) and can’t be changed.
Square mode, data mode (NRZ only)
and PRBS mode (NRZ only) are available. In ‘Direct External’ mode the
PLL is bypassed and the instrument
exactly follows the externally attached
frequency.
Frequency/Period
The main frequency is set for all channels. The frequency can also be set as
period length. The frequency range is
15 Hz to 3.35 GHz, equal to 66.6µ to
298.5 ps period. The frequency range
can also be further divided individually
for each channel.
Pulse pattern mode
In Pulse Pattern mode, each channel can be set independently to one
of the channel modes described in
‘Channel Modes’.
Burst mode
Burst mode enables the output of a
burst consisting of data repeated n
times followed by continuous zero
data. It can be started either by:
• applying a signal at the start
input.
• the start button.
• sending a command through
the remote connections.
Repetitive burst mode
This command selects a repeated
burst consisting of data repeated n
times followed by a pause of p times
zeros of the same length as the data
before the data is repeated.
The Clock is derived from the internal
oscillator.
External
The Clock is derived from the external
input. The ext. frequency is measured
once and is thereafter used to
maintain the calculated frequency
dependant values including the pulse
width or phase if set to duty cycle
mode or phase mode respectively.
External 10 MHz reference
A 10 MHz reference clock can be
applied to the clock input. This clock
is used as a reference for all timing
parameters.
Available dividers are 1, 2, 4, 8, 16, 32,
64, 128.

Channel Modes
Timing
Pulse Format
The following channel modes are
available, if the instrument main mode
is set to pulse/pattern.
NOTE: The frequency of each channel
can be optionally divided by 1, 2, 4, 8,
16, 32, 64, 128.
Square
Generates a square wave (clock) of
fixed width (50% duty cycle)
Pulse
Generates pulses with selectable
width or duty cycle.
Data
Generates data in either RZ, R1 or
NRZ format. In RZ and R1 mode, the
pulse width can be selected as either
width or duty cycle.
PRBS
Outputs a selectable PRBS (Pseudo
Random Binary Sequence) polynomial
of either RZ, R1 or NRZ format. In RZ
and R1 mode, the pulse width can be
selected as either width or duty cycle.
Delay
The delay can be set:
• as an absolute value in nano
seconds or pico seconds. The
delay remains unchanged as the
frequency or the period is modified.
• as phase (degrees relative to
period). The phase remains
unchanged as the frequency or the
period is modified.
Deskew
The deskew adjustment allows for
the compensation of e.g. cable delays.
Deskew adjustment is not available in
Direct Mode. In this case, all channels
are factory deskewed at the front
panel connectors.
Width
There are two ways to set the pulse
width:
• as absolute value in nano
seconds or pico seconds. In
absolute mode, the pulse width
stays constant when the frequency
or period is changed.
• as duty cycle (percentage of
period). In duty cycle mode, the
duty cycle stays constant when the
frequency or period is changed.
RZ
Return to zero pulse format. On 0 bit
patterns, the signal remains at the
low level. On 1 bit patterns, the signal
goes high and back to the low level
after the time specified by the pulse
width or the duty cycle parameter.
R1
Return to one pulse format. On 1 bit
patterns, the signal remains at the
high level. On 0 bit patterns, the signal
goes low and back to the high level
after the time specified by the pulse
width or the duty cycle parameter.
NRZ
Non-return to zero pulse format. The
signal remains at the low level or high
level according to the bit level of the
pattern for the entire period.
NOTE: The pulse format selection
is only available when operating
the instrument in the data/pattern
modes.
NOTE: Width adjustment is not
available if data mode is set to NRZ.

Variable Crossover
Data Polarity
For each channel, the cross over
of the NRZ signal in PRBS or data
mode can be adjusted. This is used
to artificially close the eye pattern
simulating distortion. Figure 1 shows
the normal and complement output
with cross over point set to 50% and
70% respectively.
NOTE: Variable Crossover feature is
available in NRZ mode only.
Pattern
There are two types of patterns
available:
Data
Arbitrary data up to the maximum
available memory per channel can be
setup as pattern data.
In pattern mode the polarity of the
data can be set to either normal or
inverted. When set to inverted, a
logical ‘1’ will become a logical ‘0’ at
the output and vice versa.
Levels
Pre-defined levels
Pre-defined levels allow the easy
setup of the channels for commonly
used logic families. These are: ECL,
ECLGND, LVT, LVPCL and LVDS.
Custom levels
Levels can be set to custom values in
either of two ways:
• low level and high level
• amplitude and offset
50%
50%
70%
30%

PRBS
Predefined PRBS of 25-1 to 231-1 can
be setup as pattern data.
Level protection
Output levels can be limited to a user
defined range to protect the device
under test. Level protection can be
switched on and off.
Level polarity
Level polarity can be set to either
normal or inverted. Set to inverted, the
low level and the high level values are
interchanged.
Outputs enable/disable
Outputs can be switched on and
off independently for each channel
and for each normal/complement
connector.

Auxiliary Channels
Store/Recall
Outputs
Trigger output
The trigger output can be enabled
or disabled. The levels of the trigger
output can be set as high level or low
level pair.
The trigger output can be set to one
of the following modes:
• Trigger on clock
The frequency of the trigger
output is identical to the
system frequency. It can be
further divided by n (n= 1, 2, 3, 4,
5, 6, 7…2
• Trigger on data
One Trigger pulse occurs on
the first part of the repetitive
data pattern.

-1).
Inputs
Note: The built-in input and output
terminations eliminate the need for
external bias networks and prevent
a degrading of the input/output
sensitivity
Allows permanent storage of instrument settings, including all signal
parameters and data settings. Data
patterns up to 8K bit length are also
stored. The instrument provides
memory for 9 different settings.
In addition, the 81133A and 81134A
stores the current settings at
shutdown and restored them on next
power-on.
For data patterns with more than 8K
Bit length, it is recommended to use
the special PC-based pattern editor.
Overprogramming
Many parameters can be programmed
to values that exceed the specified
ranges.
Clock input
The clock input can be ‘AC’ or ‘DC’
terminated. The ‘DC’ termination
voltage can be set. See also ‘Clock
Source - external’.
Start input
The start input can be used to start
the instrument. After being armed,
the instrument waits for the selected
edge of the applied signal.
Parameters:
• Threshold (voltage)
• Edge (rising/falling)
• Termination voltage

Pulse Pattern and Data Functionality
The 81133A and 81134A can generate an 8 KBit digital
pattern in NRZ, RZ and R1 mode. Furthermore, the 81133A
and 81134A can provide a hardware generated pseudo
random binary sequence (PRBS) from 25 - 1 to 231 - 1.
Jitter Emulation (Delay Control Input)
Full control over the signal quality of pulse and data
signals provides the Delay Control Input. With an external
modulation source (e.g. Agilent 33250A) the amount and
shape of signal jitter can be varied for stress tests or to
emulate real world signals. The external source for jitter
modulation is applied to this input. Jitter modulation can
be turned on and off individually for each channel. Either
one of two fixed sensitivities can be selected ± 25 ps or
± 250 ps resulting in a total of 50 ps or 500 ps. The amplitude of the modulated jitter is set by the voltage level of
the signal applied to the Delay Control Input. The Variable
Crossover Point feature provides additional control over
the signal quality.
