Pulse Generators

A pulse generator is either a piece of electronic test equipment or an electronic circuit used to generate rectangular pulses. While pulse generators are used for a wide variety of applications, the majority are used as bench test equipment to improve logic circuits for diverse applications.

The pulses stimulate logic circuits. Implementation of the correct types of pulses requires a substantial proportion of adjustment, such as length, delay, and repetition rate. Many purposes of a pulse generator are comparable to those of an arbitrary waveform or function generator. As a result, uses overlap or intersect, making them multi-purpose test instruments.

Precision Pulse Generator Controls

Precision pulse generators mimic the form of a nuclear particle effect in a scintillation or semiconductor detector. It also operates as a functional pulse generator with pulse processing instrumentation application. It can be calibrated to register immediately in terms of equivalent energy deposition, and the rise time of the pulse may be altered to simulate the collection time constant in the detector. Producing the pulses via a mercury-wetted relay is possible by running it from the line frequency asynchronously. It also enables measurement of spectral broadening caused by rippling in the AC line. Other controls include:

  • Pulse height
  • Relay
  • Voltage
  • Rise time
  • Polarity

Measurement of a pulse generator’s delay and rate is determined by a frequency or period adjustment using an internal or external trigger.

Delay GeneratorsDelay Generator

A digital delay generator is a component of electronic testing equipment that produces accurate delays for syncing, triggering, gating, and delaying outcomes. These types of generators are beneficial in multiple varieties of controls, processes, and experiments where the electronic timing for single or multiple events to a common timing reference is necessary. An incident may trigger the generator or initiate a chain of events. What distinguishes it from conventional electronic timing is the synchronicity of its outputs to the initiating event.


All delay generators count fast clock cycles to estimate and average time intervals. Additionally, most digital delay generators have limited programmable analog delays to generate precise resolution sequence intervals than those that are produced by the clock intervals. It is possible to eliminate timing indeterminacy by measuring trigger events with respect to compensating the analog delays and the internal clock systems. This approach overcomes the jitter and enables the internal rate generator to operate at any pace.


Digital delay generators include many trigger modes. For instance, an internal rate generator can trigger a burst of cycles, a single shot, or a timing cycle. A line trigger functions synchronously with the AC mains while a key press can trigger a single shot cycle. Rear-panel trigger inhibits input, resulting in disabling any of the pulse outputs or triggers during a timing cycle.


The outputs of a digital delay generator can be configured to generate programming defined by a pulse with widths such as falling and rising channel edges. Other features include:

  • Providing precisely defined pulses
  • Trigger holdoff
  • Prescaling

Delay parameters generate separate outputs, allow for a single trigger input, and may be extended and renewed without generation of inaccurate delays.

As a leading manufacturer of pulse and digital delay pulse generator systems, Berkeley Nucleonics Corporation is committed to maintaining a tradition of technical excellence by meeting the needs for precision timing, detector systems, and signal analysis.
