• Optical Module Specifications

The BNC Plug-In Model 040 is used with the BNC Model 6040 Optical Pulse Generator Mainframe in photodiode detector testing, fiber optics testing and other applications blue-light applications. The Model 040 is similar to the Model 065 and 085 with a different center wavelength (405-420nm) and peak power (5mW CW, Pulse).

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).
External Drive 0 to 200 MHz, pulses with zero baseline; 0 to 300 MHz, pulses with nonzerobaseline; 300 mV min. amplitude; 50 ohm input.
External Modulation 100 Hz to 700 MHz (-3 dB); 100mV rms/mW sensitivity (typical); 50 ohminput.
Module Delay 10 ns typical (fixed) mainframe's Pulse Out to Light Out. Jitter 100ps rms.


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.


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


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


Same as Model 6040 mainframe.
