FF-3303 handheld optical variable attenuator is used for continuously variable optical signal attenuation. Attenuator is used in the laser system for online testing, therefore, FF-3303 can be used in the digital system of communication devices (such as PHD, SDH) and also in the system of adopting analog modulation(CATV)
Features
- stepwise attenuating by circumgyrated dial: attenuating step 0.05dB
- Provide with function of displaying dB and dBm attenuating value
- 10 minutes Auto-off function can be activate and deactivate with keypad operation
- After instruments off, the system will have the memorizing of the value and the attenuating step, in order to restore the system back to the previous shut down state when open the instruments next time
- Portable, rugged, lightweight; Easy to use.
