Thông số kỹ thuật Máy phát xung 0.001 Hz to 20 MHz hãng BNC-Mỹ

The Model 577 Digital Delay/ Pulse Generator represents the latest in timing capabilities. Eight outputs, each configurable with its own pattern, its own trigger, its own gate, its own delay and width settings, make the 577 our most versatile instrument. The 250 ps width and delay resolution and 200 ps internal jitter give gating, triggering, delaying, clocking and synchronizing a precision sufficient for nearly every application. Add to this performance: optical or electrical outputs and inputs, pulse picking capabilities, selectable external clocks and USB/RS232 programming.

I. New Features: 

  • Illuminated Channel Enable Buttons
    • Each channel has a designated enable/disable button. When individual channels are active or enabled the buttons are illuminated. This allows for easy reference and avoids any confusion of output operability. The run/stop indicator on the front panel LCD display as well as an illuminated run/stop button further simplify setup.
  • Two Inputs to Use as Triggers and/or Gates
    • You may choose which channels use a particular trigger or a particular gate. You may select to have the inputs configured as a single trigger and a single gate, as two triggers or as two gates.
  • Optical and/or Electrical Inputs and Outputs
    • You may choose to have all electrical, all optical or a combination of both. In environments with EMI issues, optical signals become a necessity.
  • Selectable External Clock Frequency
    • For synchronizing using your external clock, you may select from a number of frequencies between 10 MHz and 100 MHz in 1 MHz increments. As an example, pulse picking at 80 MHz allows one to select one pulse out of a 80 MHz pulse stream.
  • Individual Synchronized Patterns
    • Each channel may have patterns that may be continuous, a single burst, a series of repetitive bursts, a sub-harmonic of a previous channel, a single timed pulse. All the while the pulses have their own delay and widths. A typical application is to have a channel issue series of pulses to trigger flashlamps or laser diodes. Other channels can trigger Q-switches, detectors and cameras with single timed pulses synchronized to the pulse series in the first channel. Gates can be inserted to further control whether devices are activated.
  • Auto-Save
    • Forgot to save your settings? The Model 577 stores your setup configurations while powering down. Recall is automatic on power-up.
  • Front Panel Optical
    • Many applications benefit from optical signals. For noisy environments, or communications applications, we offer an LED output stage at the front panel. This modular option can be configured for 4 or 8 outputs at 820 nm or 1300 nm
  • High Voltage and 50 Ohm Load Output Modules 
    • The inputs and outputs for the 577 consist of modules that may be changed at the factory. The standard 577 electrical output module provides adjustable amplitudes of 4 V and 20 V from a 50 ohm source impedance. On occasions that one may need a higher voltage into 50 ohms, we offer a 35 V signal into 50 ohms output module as well as a TTL/CMOS into 50 ohms output module. 
  • Electrical and Optical Outputs Simultaneously 
    • Again, the inputs and outputs for the 577 consist of modules that may be changed at the factory. Thus one may select optical, standard electrical or high voltage electrical in pairs for their instrument. For example, a 8 channel unit may have optical, standard electrical and high voltage outputs all on one instrument. Custom or additional output modules may be added as the need arises

2. Field Programmability: 

  • Field Programmability
    • The instrument can now have functions upgraded in the field, such as a special or custom feature upgrade via a fully programmable FPGA. 
  • Pulse Picking 
    • You select the external clock frequency value and insert that frequency into the external clock input of the 577. Now you may set the delay and width of a channel to select a single pulse out of this pulse train. You may select other channels to have differing delays to have them control devices that are synchronized to this single pulse. Also you may try using a second channel identically timed with the first to be a trigger for some of the remaining channels. Many timing options to consider here. 
  • 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.
