Description

The 4033 and 4034 are high performance pro- grammable pulse generators for testing digital systems and circuits based on TTL, CMOS, or ECL technolo gies. Both instruments generate clean and accurate pulses at up to 6 digits reso- lution with a repetition rate up to 50 MHz, vari- able pulse widths from 10 ns to 10 s, and pulse delays from 0 ns to 10 s. Output levels are adjustable from -10 V to +10 V, with pulse amplitudes settable from 0.1 Vpp to 10 Vpp into a 50 ohm load. All parameters, modes, and functions are programmable via the front panel or remote control commands. Additionally, the pulse generators provide selectable complemen- tary pulse and double pulse generation in contin- uous, triggered, gated, and counted burst modes.

M odels 4033 & 40 34 Front Panel Interface For added flexibility, variable rise and fall times can be programm ed from 6 ns to 100 ms. Various shapes of pulses can be obtained for applications where parameters such as linearity, switching times, or reflection times must be ana - lyzed. Programmable rise and fall times could be used to measure operational amplifier slew rates and easily test thresholds of devices and circuits. Variable Transitions In the external width pulse mode, pulse period and width are determ ined by an externally applied signal. The pulse generator then applies transition and level parameters to this signal in order to generate the pulse. A pow er supply designer for exam ple could use this feature to shape the width and period of the output signal to drive the power supply’s FET transistors while rem aining synchronized with its control circuits. External Width These generators use a menu-driven front panel keypad and control knob to adjust all parameters. The bright, easy-to-read display shows all rele - vant parameters along with a graphical represen - tation of the output pulse. If an entered parame - ter is not compa tible with the existing setup sta - tus, the operator is informed by an error mes - sage. U sers can conveniently select predefined ampli - tude levels for TTL, ECL, and CMOS signals, or choose a custom am plitude level for specialized applications.
