B&K Precision 4034 – 50MHz Dual Channel Pulse Generator

• Repetition rate of 0.1 Hz to 50 MHz
• Both channels offer full functionality and all parameters such as pulse width and transition time can be set independently
• Synchronize both channels with the push of a button
• Saves cost and bench space
• Pulse width programmable from 10 ns to 10 s

A high performance programmable pulse generators. The instrument generates pulse with a repetition rate to 50 MHz, width from 10 ns, variable delay, variable transition times and amplitude.

The 4033 and 4034 are high performance programmable pulse generators for testing digital systems and circuits based on TTL, CMOS, or ECL technologies. Both instruments generate clean and accurate pulses at up to 6 digits resolution with a repetition rate up to 50 MHz, variable 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 complementary pulse and double pulse generation in continuous, triggered, gated, and counted burst modes.

External Width

In the external width pulse mode, pulse period and width are determined by an externally applied signal. The pulse generator then applies transition and level parameters to this signal in order to generate the pulse. A power supply designer for example could use this feature to shape the width and period of the output signal to drive the power supply’s FET transistors while remaining synchronized with its control circuits.

Variable Transitions

For added flexibility, variable rise and fall times can be programmed 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 analyzed. Programmable rise and fall times could be used to measure operational amplifier slew rates and easily test thresholds of devices and circuits.

Straightforward User Interface

These generators use a menu-driven front panel keypad and control knob to adjust all parameters. The bright, easy-to-read display shows all relevant parameters along with a graphical representation of the output pulse. If an entered parameter is not compatible with the existing setup status, the operator is informed by an error message. Users can conveniently select predefined amplitude levels for TTL, ECL, and CMOS signals, or choose a custom amplitude level for specialized applications.
