Introduction to the Agilent 81133A/81134A Pulse Generator Benefits and Key Features
14 Agilent 81133A/81134A Pulse Generator User’s Guide, August 2002
Benefits and Key Features
Your advantages are:
• Fast rise times, low jitter and full parameter flexibility
When timing is critical, the 81133A/81134A’s fast rise times, the low
jitter and full parameter flexibility make it an ideal pulse, clock and
data source.
•PRBS from 2
5
-1 … 2

-1
You can evaluate the performance of a device in eye diagram
measurements with PRBS from 2

-1.
• Full signal manipulation
You can add jitter to clock or data signals with the Delay Control
Input and deform the eye with the Variable Crossover feature.
• Predefined levels
You can use the predefined levels to easily set up channels for
commonly used logic families. These are: ECL, LVPECL, LVDS.
• Data can be 8 kB of pattern memory
You can create large data patterns with 8 kB of pattern memory.
Key Features Overview
The key features are:
Frequency Divider The freqency of the output signals must always be > 15 MHz. This
limits the available range for the frequency divider (for example, for a
32 MHz signal, for the frequency divider, 2 (= 16 MHz) is available, but
not 4 (= 8 MHz)).
Frequency Range 15 MHz – 3.35 GHz
Clock Jitter < 2 ps RMS
Voltage Amplitude 50 mV … 2.00 V
PRBS 2

Transition Times 20% - 80%
(10% - 90%)
< 50 ps (< 80 ps)
Delay Modulation Range (Jitter) ± 250 ps, ± 25 ps selectable
Data 8 kBit memory, RZ, NRZ,
Burst Capability
Delay Range -5 ns … 230 ns
Frequency Divider 1, 2, 4, ... 128
