Berkeley Nucleonics’ 500 series Delay Generators offer industry-leading precision in a multitude of user-friendly form factors. Our Model 575 offers, 2, 4, or, 8 independent outputs that are designed to provide cutting edge and cost-effective solutions. Our DDG’s generate and synchronize multiple pulses for a wide range of applications. The delay and pulse width for each channel are independent and digitally controlled which makes the instrument ideal for situations that require synchronizing several different events, all making the 575 one of the most flexible delay generator on the market with a host of optical/electrical inputs and outputs.

Field Programmability

Custom Output Modes

Custom Modules such as the TZ-50 give users an expand list of capabilities with the Model 575. One example is our TZ-50 option, which allows customers a TTL signal into 50 ohms expanded. 

Negative Delay

Use the handy negative delay feature to reference one channel with respect to another channel in positive or negative time increments. By allowing a channel to reference another channel as its trigger, you can synchronize the channels with respect to each other.

Note that Negative Delay cannot trigger a channel before your initial trigger. It is intended to complement the channel referencing option.

Feature Summary Optical Inputs and Outputs

Berkeley Nucleonics provides the option of having combinations of optical and electrical inputs and outputs. For example, one may have an eight-channel unit with electrical input and four optical and four electrical outputs. One may also order all-optical inputs and outputs.

Some advantages of optical fiber

  • EMI Immunity
  • Level translation – Move triggers from one potential to another
  • No sparks and no high voltage pulses to overcome noisy environments
  • Smaller size and much less weight than copper cables
  • Span longer distances without signal degradation
  • Can easily fit in existing installations

Wavelengths, connectors, and fiber considerations

  • Commercially available transmitters and receivers to facilitate your interface
  • One may select either 820 or 1300nm
  • ST is the standard connector with 0.2dB typical
  • Compatible with 50/125 um, 62.5/125 um, 100/140 um and 200 um HCS fibers.
  • Distances up to 1.5 km using these receivers and transmitters
