Model 6040 pulse generator

BNC Model 625A Signal Generator

The Model 6040 pulse generator provides superior performance characteristics. For example, the timing accuracies of 0.01% for frequency and 0.2% for delay and width are unusual for a pulse generator. The triggering jitter of 25 ps provides synchronizing capabilities usually associated with only the very best digital delay systems. Plug-in modules let you select the output configuration you currently need.

Even the mainframe 6040 without any module provides capable positive and negative outputs. Capabilities of the mainframe with its modules include: single pulse, double pulse, impulse, external drive, external modulation and CW. The modules themselves determine which of these capabilities are available. Some modules can operate to full repetition rate of the mainframe; others are limited to a smaller number.

  • Adjustable rates up to 100 MHz
  • 5V to 900V amplitudes
  • 635, 850, 904, 1064, 1300 and 1550 nm wavelengths
  • 1 ns resolution delay and width control

Modules for 6040

Electrical Modules

These interchangeable modules provide electrical signals from 5V, 180ps risetimes to 900V, 10 ns risetimes. The higher amplitudes have slower risetimes and the slower risetimes result in reduced maximum rep rates.

Optical Modules

These interchangeable modules provide wavelengths of 635 nm, 650 nm, 660 nm, 850 nm, 904 nm, 1064 nm, 1300 nm and 1550 nm. Other wavelength options may be available so check with the factory if you have special needs. The optical modules offer rep rate, delay and width control as well as amplitude adjust essentially providing the optical equivalent of an electrical pulse generator. For all the modules, light is conveniently provided at end of an optical fiber for easy routing on an optical bench or to a test system.
