Used in Conjunction with BNC Model 6040 Optical Pulse Generator Mainframe, the Model 155H is similar to the Model 106H, a high power Light Pulse Generator without CW Operation. The pulse wavelengths are selectable by the user and range from 1535nm - 1585nm. Standard power is 50mW, but new laser source may be selected offering up to 200mW. Fiber options exist as well: Single Mode (9/50, 9125) or Multi Mode (50/125).

STORE
A ROM determines the instrument's allowable operating conditions and units 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 mainframe to produce the predetermined 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.
