Impulse output fixed at 100 uW baseline, 1.5 mW peak (typical). **Custom Peak Power** 065 – 10 mW | 085 – 20 mW | 095 – 20mW **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) ##### Timing **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. ##### 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. #### Downloadable Resources Downloadable resources such as datasheets, firmware, software, drivers and products manuals.
