Models 155 provide operating capabilities unavailable from other optical sources. Among them, repetition rates to 100 MHz and precision control of amplitude and time domain.
Combined with the BNC Model 6040 Mainframe, these modules generate fast pulses, subnanosecond impulses, and CW light while maintaining the excellent timing accuracy, low jitter, and nanosecond resolution of the mainframe. In addition, the model 155 has two inputs for stimulus from external signal sources: External Drive and External Modulation.
With External Drive, the optical outputs are fast edge speed, flat-top pulses corresponding to the input signal timing. In External Modulation, an electrical signal is converted into an analog optical form. Thus, it is now possible to transform signals from instruments such as a function or arbitrary waveform generator into their optical equivalents at 1550 nm, as well as the other wavelengths described in the Model 6040 product bulletin.

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 and output pulse parameters (trigger level, delay, width, etc.).
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). (Installed in Model 6040 Mainframe, est. 24 lbs. shipping)
ENVIRONMENT
Same as Model 6040 mainframe.
