Exceptional Versatility, Performance and Precision
High Performance Pulses

The Model 550 features variable pulse widths from 10 ns to 10 s, delays from 0 ns to10 s with up to 6 digits resolution and adjustable output levels from –10V to +10V, with pulse amplitudes from 0.5V to 10Vp-p into 50 ohms load.
The Pulse Generator also features selectable complementary pulse and double pulse, in continuous, triggered, gated and counted burst modes.
The Model 550 allows selection of predefined amplitude and offset for critical stimulus and testing of major semiconductor technologies as TTL, CMOS and ECL.

Variable Transitions
To make operation flexible, variable transitions (rise and fall times) can be programmed from 5 ns to 10 ms. With the flexible transition times, various shapes of pulses can be obtained for applications where parameters such as linearity, switching times or reflection times must be analyzed. Operational amplifiers slew rate can be measured or thresholds of devices and circuits can be easily tested using programmable rise and fall times.

Fast and Easy Operation
To make operation easy, Model 550 interface with the operator in a straight- forward manner by which the front panel display always shows the parameter being varied and its value. If a new parameter just entered is not compatible with the existing setup status, the operator is informed via an error message. Test setups, up to 99 locations, can be stored and recalled. This feature allows simple test sequence development as well as no need for a controller in repetitive tests, with reduced bus traffic in ATE applications. Last user setup is also retained at power down.

Internal Calibration
The Pulse Generator Model 550 is self- calibrating itself by means of internal time and voltage reference. With no need to open the case, the Pulse Generator benefits of improved accuracy, extended calibration interval and low downtime.

GPIB Programming
The Model 550 has been designed for use in ATE systems. All parameters, modes and functions are programmable and fully compatible with IEEE-488.2 and the Standard Commands for Programmable Instruments (SCPI) language.
