Introduction to the Agilent 81133A/81134A Pulse Generator Benefits and Key Features
14 Agilent 81133A/81134A Pulse Generator User’s Guide, January 2005
Benefits and Key Features
Your ad va nt age s ar e:
• Fast rise times, low jitter and full parameter flexibility
When timing is critical, the 81133A/81134A’s fast rise times, the low
jitter and f ull paramete r flexibili ty make it an id eal pulse, cl ock and
data source.
•PRBS from 2
5-1 … 231-1
You can evaluate the performance of a device in eye diagram
measurements with PRBS from 25-1 … 231-1.
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 patter n 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 25-1 … 231-1
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
