Introduction to the Agilent 81133A/81134A Pulse Generator The Agilent 81133A and 81134A Pulse/Pattern Generators are high- end, easy-to-use tools for generating pulses, patterns and data at speeds up to 3.35 GHz. They are ideal instruments for testing logic devices (for example, ECL, LVDS, LVPECL) and other digital devices with clock rates from 15 MHz to 3.35 GHz. You can use the Pulse Generators for applications where timing and performance are critical and full control over signal jitter is required. The instruments are ideal data and pattern sources for eye diagram measurements. 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 25-1 ... 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 pattern memory You can create large data patterns with 8 kB of pattern memory.
