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 904nm and power can be selected up to 10mW from a single mode 9/125 fiber.
|Spectral Peak||904nm +/- 15nm (nominal)|
|Spectral Width||less than 5nm (nominal)|
|Power Levels||0 to 2 mW baseline, 100 uW to 2 mW peak (Custom up to 10mW); independently adjustable. Impulse output fixed at 100 uW baseline, 1.5 mW peak (typical).|
|Resolution||10 uW, 100 uW to 2 mW pulses; 0 to 2 mW in External Modulation and CW.|
|Transition Times (20% to 80%)||500 ps rise time, 1.5 ns fall time (pulses with zero baseline) 1 ns rise time, 1 ns fall time (pulses with non zero baseline).|
|Dynamic Range||13 dB, pulses with zero baseline; 20 dB, pulses with nonzero baselineExternal Modulation and CW.|
|Accuracy (Nonzero Baseline)||Absolute: +/- 1 dB, 200 uW to 2 mW. Relative: +/- 0.5 dB, 200 uW to 2 mW pulses;+ 30 uW, 200 uW to 2 mW for External Modulation and CW.|
|Temperature Coefficient||0.05 dB/°C.|
|Fiber||6/125 Single Mode Fiber standard (Contact Factory for custom); 0.21 NA.|
|Connector||ST Standared (Contact Factory for custom)|
|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 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.
The RAM-stored settings can be manually or bus transferred to the mainframe to produce the predetermined 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.
