575 | 0.001 Hz to 10 MHzDigital Delay / Pulse Generator

모델 575는 매력적인 가격으로 다중 채널 250ps 해상도 타이밍, 지연, 게이팅, 펄스 및 동기화 기능을 제공합니다. 기존의 디지털 지연 및 펄스 발생기 모드 외에도 많은 실제 작동 모드와 기능이 있습니다. 유용성과 가치를 위해 – 비교할만한 것은 없습니다.

각 채널은 지연과 폭을 모두 제공합니다. 2 채널 모델 575는 경쟁적인 4 채널 장치와 동일한 지연 및 폭 기능을 제공합니다. 575는 옵션 이더넷, 고전압 및 이중 입력 트리거 옵션과 함께 2, 4 및 8 채널 구성으로 제공됩니다. 최고의 정밀 타이밍을 나타내는이 디지털 지연 / 펄스 발생기는 최대 1000 초 동안 250ps 해상도로 정밀한 지연 및 폭을 제공합니다. 내부 클록 (50ps)과 외부 트리거 (800ps)를 모두 사용하는 낮은 지터는 많은 장치를 제어하는 ​​데 필요한 타이밍을 사용자에게 제공합니다.

이는 여러 펄스 또는 게이트 신호가 서로 또는 공통 트리거에 대해 지연되고 시간이 필요한 경우에 특히 유용합니다. 한 채널을 다른 채널의 트리거 참조로 사용하여 필요할 때 타이밍 지연을 잠글 수도 있습니다.

Field Programmability

Customer 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.

Summary of Electrical Outputs

  • AT20 – The standard 575 provides a selectable TTL or 20V into a high impedance from a 50 Ω source impedance. The TTL level is fixed; the 20V level is adjustable down to 2V. The risetime is 3 ns.
  • TZ50 – Choose this option on 2, 4, or all 8 channels to get TTL levels into 50 Ω. The standard output provides 4V pulses from 50 ohms which becomes 2V into a 50 Ω load. The TZ50 provides 4V into 50 Ω. The risetime is 3 ns.
  • AT45 – Choose this option to get 45V into 50 Ω. This option provides an adjustable 3-45V pulse into 50 Ω. The risetime is a respectable 2 ns. This is our newest option and will replace the AT35 in many applications unless price sensitivity makes the AT35 more attractive **Due to the power consumption and heat restrictions, only a maximum of four AT45 channels can be added on a single unit.
  • AT35 – This is our standard high voltage module. Order 2, 4, or all 8 channels. This gives you 35V into 50 Ω. This option provides an adjustable 35V pulse into 50 Ω. The risetime is 30 ns.
  • TZ35 – This is a combination of AT35 and TZ50 module. Order 2, 4, or all 8 channels. This gives you 35V into 50 Ω and TTL (4V) into 50 Ω. This option provides an adjustable 35V pulse into 50 Ω. The risetime is 30 ns.

Summary of Optical Outputs

  • L82 – 820nm Optical Output
  • L130 – 1300nm Optical Output

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 an 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
