Description
Overview
GAOTek optical variable handheld attenuators are used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the online testing, therefore, GAOTek optical variable handheld attenuators can be used in the digital system of communication devices (such as PHD, SDH) and in the system of adopting analog modulation (CATV).
Features

- Provide with the function of displaying dB and dBm attenuating value
- The alternative function of 10 minutes Auto-off without operation
- Instrument memorizes attenuating values and steps for system restoration
