The Model 090 Optical Module is used with the BNC Model 6040 Optical Pulse Generator Mainframe, much like Model 065 or Model 085. The primary difference with this module is that the spectral peak is 650nm.

Overview

Features
  • Trigger Internal 0.01 Hz to 100 MHz; external 0 to 100 MHz
  • Pulse Width 3 ns to 640 s
  • Impulse 400 ps typical (fixed)
  • Delay 0 ns to 640 s (plus fixed delay)
Applications
  • Photo Multiplier
  • Photo Detector
  • Fiber Optics Testing

STORE

A ROM determines the instrument's allowable operating conditions andunits of display applicable for the installed module.
A nonvolatile memory (RAM) in each module stores up to ten complete settings of operating conditions (trigger level, slope, etc.) and output pulse parameters

RECALL

The RAM-stored settings can be manually or bus transferred to the mainframeto produce the pre determined outputs.

WEIGHT

2 Ibs net (0.9 kg); 5 Ibs shipping (2.3 kg). (When installed in a Model 6040 Mainframe, est. 24 lbs. shipping)

AMBIENT

Same as Model 6040 mainframe.
